Long Essay on Noise Pollution in English 500 words

The long essay on Noise pollution is suitable for students of class 7, 8, 9, 10, and competitive exam aspirants.

Noise pollution or sound pollution refers to the dangerous and unwanted level of disturbance caused by noise. Noise is measured in decibels or dB. A sound more than 85db is said to be a damaging level of sound that, over time, can causing hearing loss. Noise pollution is a problem faced all over the world.

There are numerous sources of noise pollution. One of the primary causes is industrialization, especially in urban areas. Industries use heavy equipment such as generators, compressors, mills, etc. that make high pitched sounds that are very unpleasant and cause a disturbance. Road traffic is another major contributor to noise pollution. Increased transport of cars, motorcycles, trucks, etc. have to lead to increased noise disturbance on the road.

Construction of roads, buildings, apartments, highways, etc. uses heavy equipment such as excavators, compressors, hammers, etc. These create a lot of noise, causing disturbance to its surroundings. Poor urban planning such as congested living spaces, large families living in a small area, parking spaces, etc. causes many fights as they are competing for the same resources. The use of firecrackers during festivals is also a source of noise pollution. These crackers generate very high pitched and sudden sounds. They are contributing to noise as well as air pollution. Another source of noise pollution includes playing loud music, especially during social events like marriages. Low flying aircraft of the military also cause noise pollution. Ocean sound pollution is caused due to submarines. Other sources of noise pollution include household equipment, air conditioners, kitchen appliances, etc.

Noise pollution primarily affects a person’s hearing, leading to hearing impairment to even permanent loss of hearing. It causes an increase in blood pressure, hypertension, fatigue, and cardiovascular diseases. Noise pollution also disturbs a person’s state of mind causing disturbed sleep patterns, stress, aggressive behavior, decreased concentration, and poor quality of life. Noise disturbance is extremely dangerous to elderly people and pregnant women.

Noise pollution also affects wildlife and marine life. Animals have a more advanced hearing. Noise pollution can impact their listening skills and cause changes in their behavior, starting with a pet at home. It leads to changes in their hearing due to which their communication also becomes affected. They are unable to hear properly during migration as they require sound to find their way. Noise pollution also affects crop production. Ocean sound pollution causes internal damage such as cardiovascular problems and physical problems such as hearing impairment in marine life. They are forced to leave viable habitats.

There are noise pollution preventive measures available. Soundproof walls and windows are one way to prevent noise pollution from entering the premise. Faulty equipment must be checked and repaired regularly. Needless honking must be discouraged. Many hospitals and schools are silent zones to ensure that disturbance does not occur. Rules to prevent noise at certain hours are in place, which many governments have implemented. Using earplugs and switching off appliances when not required, can also help. Planting trees can also help as they absorb noises. International Noise Awareness Day is witnessed every year, usually on the last Wednesday of April. This day was marked on April 29 in 2020.

Short Essay on Noise Pollution in English for Kids 200 words

ENCYCLOPEDIC ENTRY

Noise pollution.

Noise pollution can cause health problems for people and wildlife, both on land and in the sea. From traffic noise to rock concerts, loud or inescapable sounds can cause hearing loss, stress, and high blood pressure. Noise from ships and human activities in the ocean is harmful to whales and dolphins that depend on echolocation to survive.

Noise pollution is an invisible danger. It cannot be seen, but it is present nonetheless, both on land and under the sea. Noise pollution is considered to be any unwanted or disturbing sound that affects the health and well-being of humans and other organisms.

Sound is measured in decibels . There are many sounds in the environment, from rustling leaves (20 to 30 decibels ) to a thunderclap (120 decibels ) to the wail of a siren (120 to 140 decibels ). Sounds that reach 85 decibels or higher can harm a person’s ears. Sound sources that exceed this threshold include familiar things, such as power lawn mowers (90 decibels ), subway trains (90 to 115 decibels ), and loud rock concerts (110 to 120 decibels ).

Noise pollution impacts millions of people on a daily basis. The most common health problem it causes is Noise Induced Hearing Loss (NIHL). Exposure to loud noise can also cause high blood pressure, heart disease, sleep disturbances, and stress. These health problems can affect all age groups, especially children. Many children who live near noisy airports or streets have been found to suffer from stress and other problems, such as impairments in memory, attention level, and reading skill.

Noise pollution also impacts the health and well-being of wildlife. Studies have shown that loud noises can cause caterpillars' dorsal vessels (the insect equivalent of a heart) to beat faster, and cause bluebirds to have fewer chicks. Animals use sound for a variety of reasons, including to navigate, find food, attract mates, and avoid predators. Noise pollution makes it difficult for them to accomplish these tasks, which affects their ability survive.

Increasing noise is not only affecting animals on land, it is also a growing problem for those that live in the ocean. Ships, oil drills, sonar devices, and seismic tests have made the once tranquil marine environment loud and chaotic. Whales and dolphins are particularly impacted by noise pollution . These marine mammals rely on echolocation to communicate, navigate, feed, and find mates, and excess noise interferes with their ability to effectively echolocate.

Some of the loudest underwater noise comes from naval sonar devices. Sonar , like echolocation , works by sending pulses of sound down into the depths of the ocean to bounce off an object and return an echo to the ship, which indicates a location for object. Sonar sounds can be as loud as 235 decibels and travel hundreds of miles under water, interfering with whales’ ability to use echolocation . Research has shown that sonar can cause mass strandings of whales on beaches and alter the feeding behavior of endangered blue whales ( Balaenoptera musculus ). Environmental groups are urging the U.S. Navy to stop or reduce using sonar for military training.

Seismic surveys also produce loud blasts of sound within the ocean. Ships looking for deep-sea oil or gas deposits tow devices called air guns and shoot pulses of sound down to the ocean floor. The sound blasts can damage the ears of marine animals and cause serious injury. Scientists believe this noise may also be contributing to the altered behavior of whales.

Among those researching the effects of noise pollution is Michel Andre, a bioacoustics researcher in Spain who is recording ocean sounds using instruments called hydrophones . His project, LIDO (Listening to the Deep Ocean Environment), collects data at 22 different locations. Back in the lab, computers identify the sounds of human activities as well as 26 species of whales and dolphins. The analysis aims to determine the effects that underwater noise is having on these animals. Andre hopes his project will find ways to protect marine animals from the dangers of ocean noise.

Prolonged exposure to loud noises can result in permanent hearing damage. According to the Centers for Disease Control and Prevention (CDC), about 24% of adults in the United States have some degree of noise-induced hearing loss. This is a significant concern, as hearing loss can affect our ability to communicate and enjoy life fully.

The Need for Regulations

To address noise pollution, governments and communities have implemented regulations and noise control measures. These may include setting noise limits for vehicles, enforcing quiet hours, and soundproofing buildings. These efforts aim to reduce noise pollution and protect our health and environment.

Personal Responsibility

While regulations help, we can also take personal responsibility for reducing noise pollution. Simple actions like lowering the volume of our music, using headphones in public places, and maintaining our vehicles to minimize noise emissions can make a difference.

Conclusion of Essay on Noise Pollution

In conclusion, noise pollution is a real and often underestimated problem that affects our health, environment, and quality of life. It can disrupt our sleep, hinder our learning, harm our wildlife, and even lead to permanent hearing loss. Recognizing the impact of noise pollution is the first step in finding solutions. By advocating for quieter environments, supporting regulations, and being mindful of our own noise, we can work together to reduce noise pollution and create a quieter, healthier world for everyone. It’s time to turn down the volume and appreciate the importance of peace and quiet in our lives.

Introduction

Noise as one of the greatest hazards of this world, noise pollution in law, application of methods in real life, the truax model, works cited.

Little sound and noise we all require to live in the society but when this noise and sound becomes unbearable and very loud, it turns to noise and sound pollution. The word noise originated from the Latin term “nausea”, meaning uncalled for. “Noise is defined as unwanted sound; sound, which pleases the listeners is music and that which causes pain and annoyance is noise”. (Jaiswal & Jaiswal, 327) However, “Sound is a kind of energy that allows the particles in the air, a liquid or a solid to vibrate”. (Occupational Health Clinic for Ontario Workers, Online)

For all living inside the arena of the technological world and amidst the cities and towns, noise has become a part of life except for all those fortunate who are still living in the laps of nature away from any busy roads, screaming industries and factories, sounds of loud music, etc. Twenty hours a day we have to bear these sounds and we have increased our toleration level and endurance towards them, but amidst this too when sound becomes too loud, it becomes unbearable causing health hazards.

In the early years of the 1890s, journals of America and London raised the people’s consciousness towards noise as one of the greatest hazards of this world, but people had already got aware to the noise problem during the time when “Epic of Gilgamesh” was written and read in the 3 rd millennium BC. In the Sumerian account of the flood, it was written, “in those days the world teemed, the people multiplied, the world bellowed like a wild bull, and the great God was aroused by the clamour. Enlil heard the clamour and he said to the Gods in council, “the uproar of mankind is intolerable and sleep is no longer possible by reason of the babel. So Gods in the heart were moved to let loose the diluge”.

Now the noise problem is no doubt has become a matter of grave concern for politicians, environmentalists, and basis for legal actions and a topic for health-conscious people. But rarely it is considered as a human problem that is a part of the system acoustic communications. Sound creates a relationship between the individual and environment whereas noise becomes a mediator but creates a negative impact on such mediations and makes the contact between the individual and communicator impossible; it also creates hindrance on the part of effective communications. But what constitutes noise and when sound becomes noise, the concept of this since Helmholtz has been, “the physical acoustic definition of noise has been that it is a non-periodic vibration, by comparison to musical sound, which has a periodicity and therefore a pitch”. (Traux, 95).

However, music can also become a source of irritation and become a noise for someone who is unaccustomed and annoyed by it. As per law, the quantitative noise is defined functionally as regards to the sound’s intensity level to determine the extent to which it could be acceptable or not. The problem with the legislation law is finding out the right level above which the sound becomes unacceptable enough to be considered as noise. (Traux, 95) The noise pollution should be considered by the duration of the sound, the frequency of noise, and whether there is any control to the sound or not. The British Columbia Workers’ Compensation Board (WCB) has fixed the limitations of sound to be 85 decibels in the workplace and above it is harmful. If sound reaches 120 decibels, it becomes very painful and at 140, it is very harmful. However, at home the noise level above 50 decibels is quite normal and above 55 is serious. While in hospitals and schools, the safe level of sound is 35 decibels. (Ban the Canons, Online) The noise if reaches above the safe level cause tremendous impact on health like increase in stress, high blood pressure, loss of sleep, inability to concentrate and learn and loss of productivity. Noise pollution can impair hearing in children; reduce their attention level and cause negative impact on them.

We are staying in British Columbia and near the villages where farmer’s blast their cannons from dawn to dusk and they are very loud. They have the devices like leaf blowers that reciprocate the novel that reaches to the level of 75 or 80 decibels. The noise of the boom cars can reach till 100 decibels, but propane cannons can go to the range of 130 decibels. Though these canons are regulated by the British Columbia, they begin at 6: 30 am and blast until 8: 00 pm. And the areas, which are not regulated, farmers blast their cannons from dawn to dusk. The blast of propane cannons is like a shotgun, ranging between 120-130 decibels. From our home we often have to hear two blasts every single minute and many have to hear five to six blasts every single minute. These blasts occur during the berry season, which stretches from the month of late June to the whole month of October. It is claimed that these propane cannons are neither very necessary nor are very effective and the farmers are breaching the Langley Township Noise Bylaw. (Ban the Canons, Online).

I did some thought-provoking methods to deal with the situation. I along with my neighbors prepared some brochures and campaigning plans and went personally to the farmer’s houses to explain them how much they are causing noise pollution and they should substitute these propane canons with some other method that do not make too much noise and are economically feasible too. Secondly we went to visit the local MLA to personally administer the farmer’s use of propane cannons and govern the farmers towards reducing the noise immersing from the use of cannons. Still the noisemakers are ignoring and bent on using the cannons above the normal decibels. Then I decided to contact the Minister of Agriculture, and the Farm Industry Review Board (FIRB). They have responsibility to pursue the right to Farm Legislation, which has the clause to allow the farmers to the use of the propane cannons. But, if they want they are entitled to modify or make changes in this legislation to check the farmers to control their use of cannons. Many of these issues like that of noise pollution comes under the Vancouver Charter whereby the powers of Council would be exercised by bylaw. The bylaws governing city of Vancouver are numbered beginning with by-law No 1 that is the law, which was enacted first and then continued subsequently. The first by law was passed on 18 th May 1886 and then over many years around 10,000 laws have been passed. The Noise Bylaw of city controls and legalizes construction works, vehicles and noise immersing from households. (SoundSmart, Online) People also formed Urban Noise Task Force. This is a group of citizens, who with the help of the city staff and councilors recommends and makes suggestions to the city for making improvements in Vancouver’s soundscape. There is also on the anvil the Vancouver Transportation Plan. It had proposed that reviews should be conducted on the most important arterial roads in the city for their performance and the way they are dealt with and are being used in relationship to the neighbors. The city is also planning for the quite payment towards most important transportation corridors. The Urban Noise task force has been created to check on the increasing noise in the city and the extent to which it is affecting the daily lives of Vancouver.

In Canada, there are very few laws at the national, provincial, or state levels to govern the noise pollution. As a result, most of the Canadian and EU countries regulations of the law are governed at the municipal level. There are different noise laws and ordinances in municipalities among different areas. The laws constitute certain ordinances that may prohibit persons against creating noise or may place certain guidelines on the level of noise allowed for certain time duration. There is slight difference between the laws in the cities and villages as regards the control of noise pollution is concerned. In cities, there are several laws and governing bodies to check the lawbreakers while in the villages of British Columbia, either MLA can put a control on the noise pollution or there is right to Farm Legislation whose discretion is in the hands of the Minister of Agriculture, and the Farm Industry Review Board (FIRB). Particularly for British Columbia, there is one law, which is the Langley Township Noise Bylaw. For e.g. “the law states that the number of discharges from any noise scare device is limited to a maximum of one discharge in any three minute period of time”. (Noise Control by law 1988 No 2573, Online) The difficulty in the provision of the law is inability on the part of the province to control the direct use of the devices.

Sounds, which exceed the level more than determined, become noise. What makes one sound a noise is determined by the intensity of the volume of sound. It depends on the listening capacity of the people also. For many people what constitutes sound could be noise and for many what is noise is sound and for many, sound is a pleasure. When we look at the day-to-day to life, it is very simple to determine what constitutes sound and what constitutes noise. For e.g. when we listen to the music, it would sound very appealing to the ears and give soothing effect and if this music is interrupted by the other sounds like unnecessary playing of drums, or shouts of children or sounds of traffic on the roads, it would become a noise, which could be very irritating. But it is very difficulty to consider the same in case we have to determine sound and noise in theoretical terms and on the basis of its established set norms and prescribed limits. The legislation of each area or place has considered the proximate level of sound and if the sound reaches above that level, it becomes noise requiring strict consideration. The problems come in legislation in determining the nature of sound and in determining if really this sound is noise. If someone is typing something on a typewriter, it could be very annoying to someone even if its sound is low. It is also not necessary that unpitched sound is noise; it could be a sound from music as well.

The Truax model understands the relationship between the listener and the sound. This model describes the relationship between the listener and its environment, which is interfered with the help of the sound and triangular relationship, is therefore created. Any change occurring due to any one of the components either due to habituation, or any other disturbances has an effect on the soundscape and that what happened in this process.

The above example I cited is related to the environmental acoustics. “This acoustics studies show different frequencies behave during propagation. When the sound waves comes into contact with objects, its energy is transmitted through the object, absorbed within it, or reflected from it with varying degrees of efficiency depending on efficiency.” (Traux, 5) This happens when the cannons blow. They reciprocate the sound waves above the level prescribed. These sounds create a disturbance between the relation between the listener and its environment.

Every now and then we are facing the noise pollution and as it is difficult to analyze, more difficult is to follow the legislation. In Canada, the noise pollution is controlled at the Federal, provincial and municipal levels and government has adopted different roles and responsibilities as regards to the noise pollution issues. For e.g. Federal government has responsibility for ensuring noise pollution does not occur in case of consumer products, equipment, and vehicles. But, these regulations do not follow when these products are sold and after they are used and depleted. The sold and depleted products often exceed the prescribed sound levels, for which federal government is not responsible. The federal government has also mentioned about the guidelines for control of pollution through provincial transportation systems including aircraft, trains and waterways. As a part of its provincial role, government fixes rules in the area of land use planning. They help the municipalities in pursuing the noise control by-laws to decrease the sources of noise pollution. They also have provisions to check the noise levels immersing from consumer products, equipments and vehicles. And in municipal level role too, municipalities see to it that noise control bylaws are followed adequately in the provincial areas. (CBC News, Online).

The complexities of the noise immersing from the different corners of our lives create hurdles in the path of the government at different levels for effective application of the legislation.

What is Noise pollution?

Noise pollution is a type of pollution that does not directly affect the environment but has adverse effects on the hearing abilities of the inhabitants of our ecosystem.

Hearing of an organism is directly linked to the nervous systems internally.

Hence noise pollution affects the mental health and disturbs the delicate balance of an individual in case of over-exposure to noise levels beyond a certain decibel.

There may have been many instances, especially when you’re living in a city, that you’ve been so annoyed with the noise around you, that you lose your composure. You grab your ears and just wait for the noise to stop.

That is the essence of noise pollution. It comprises of all the loud noises around you, caused by vehicular traffic, heavy machinery in factories and sometimes, the disturbance of trains and aeroplanes, if you live near an airport or railway station .

The blaring sounds from loudspeakers and high speakers are not to be left behind, especially when there are processions or big festivals taking place.

Let us ponder over a few examples for better understanding.

Whales are known to emit their call louder when they detect a submarine since a submarine uses SONAR and other sound oriented devices for communication and navigation.

The SONAR dampens the whale’s call, making it less effective, which in turn might lead to some members not hearing it and missing some vital signal, like a hunting call.

Causes of noise pollution

Let us first begin by trying to understand how noise is generated technically.

Noise basically is a mixture of all sounds around us. These sounds originate from various sources.  Inside the waveform of a noise, we can find overlapping waveform indicating mixed and jumbled outputs rendering ‘noise’.

The outcomes may contain undesirable and irritating waveform called noise. Noise pollution is more prominent in urban areas than in rural areas.

This is because rural areas have only half the amount of vehicles, minimal amount of factories and other sources producing loud noises.

It is more discomforting and annoying in particular to senior citizens, who seek a calm and peaceful atmosphere in their days of retirement. In India, festivals are a crucial part of our culture and thus, are given utmost importance.

But the celebrations and proceedings involved with these festivities result in noise pollution on a wide scale.

This scenario especially gets worse when people disregard the fact about patients in hospitals, nursing mothers, pregnant women and ill patients who need relief from such blaring noises.

Similar is the case with wedding celebrations. Nowadays, almost everyone holds a wedding procession which involves the bride and groom, either walking or on horses or carriages, slowly proceeding towards the groom’s house.

Celebrations take place on a large scale involving huge loudspeakers and noise from trumpets and drum beats causing inconvenience to residents and other establishments, including schools, colleges, hospitals and other religious establishments like temples and churches.

Well known incidences of noise pollution occur during festivals, normal, everyday traffic on the road, etc.

During festivals like Ganesh Chaturthi , Diwali etc the occurrence of sound pollution is really high.

Diwali causes noise as well as Air pollution , people celebrate Diwali for their joy, and indeed they burst crackers that create massive noise.

Traffic on the road is the primary reason for sound pollution in big cities. There are many other factors too that cause the deadly noise pollution.

Effects of noise pollution

Our human ear can detect sounds in the frequencies between 20Hz to 20 KHz. But constant exposure to sound beyond certain intensity is harmful to the ears.

We already know that sound intensity is measured in Decibels, also denoted as dB. In a normal airport, a plane that is landing or leaving the run way creates a noise exceeding intensities of 120 dB.

There are chances of irreversible damage to the human ear when exposed to noises above 80 dB. Instances of noise have been recorded from the ancient times in the cities of Rome, on account of the dawn of industrialization.

Poorly planned cities and towns are another reason where residents have to become victims of noise pollution. If the city is near an industrial area, then the residential areas face heavy instances of noise pollution.

Though the human ear’s maximum capacity of tolerating noise cannot be exactly measured, it is believed that the intensity is about 80 dB.

Continuous exposure to sounds of intensities higher than this may lead to a myriad of health problems. It may lead to physical as well as psychological changes.

A person shows increased levels of stress and becomes prone to mental illnesses if he is prone to irregular levels of noise.

Every person’s tolerance is inbuilt differently and the ability of a person to tolerate noise provides him stability from within. Beyond that threshold level, the mind senses disturbance and gets irritated by the effects of noise.

This irritability is then transferred to the inner regions on the brain wherein complex reactions alter normal functioning of brain components.

When this process happens over long periods of time, the brain functioning itself gets altered and that’s when we say that an abnormality has occurred in the mental well being of a person.

The chances of a cardio vascular disease are also highly elevated. It is not just humans who are affected, but animals in the vicinity too face disturbance.

Dogs, with a higher sense of hearing, may get their ears damaged by exposure to higher levels of noise pollution.

Wildlife is adversely affected, as the loud man-made noises drown the mating calls, warning alarms and threat noises that animals use normally to communicate with one another.

For example in birds, the bird robin is observed to sing more likely at night, in a heavily noise polluted area since, in the day time, the noises are significantly louder.

Solutions for noise pollution

The threat of noise pollution is being realized and the governments are taking measures to reduce them.

In India too, certain rules and regulations have been set up regarding noise generation and emission. But the enforcement of these laws is not incorporated on strict terms and thus the defaulters escape scot-free.

It is good to know that there are many NGOs (non-government organizations) that have taken the initiative to reduce noise pollution and so far they’ve made tremendous progress, especially in the urban areas.

The rural areas, unfortunately, still face the wrath of noise pollution. It is up to us, the educated urban crowds, to control and prohibit the curse of noise pollution.

It’s also good to create awareness among the rural inhabitants regarding the ill effects of noise pollution.

Today, everyone has come to know the deadly effect of noise pollution. The government has taken some of the crucial steps to reduce the sound pollution.

The noise of Loud Speakers should be limited and should not cross beyond a certain decibel. An individual or group isn’t permitted to use loud speakers in the vicinity of schools, colleges, and hospitals.

Government has imposed strict restrictions and posed limitations on the use of loudspeakers during festivals. It has posted a big list do’s and don’ts and applied the rules at appropriate regions of high noise traffic.

The effects of noise pollution is not restricted to human beings alone, it has deadly impacts on lives of animals as well.

To control this type of pollution, people should create awareness on its impact on human health. Airports should be situated far away from residential areas.

Manufacturing industries such as steel and iron establishments should be situated far away from residential complexes.

It’s more of an individual effort to control noise pollution.  We may not be able to totally stop noise pollution , but we can definitely take steps to reduce it by a great level.

noise pollution , unwanted or excessive sound that can have deleterious effects on human health, wildlife, and environmental quality. Noise pollution is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highway, railway, and airplane traffic and from outdoor construction activities.

Sound waves are vibrations of air molecules carried from a noise source to the ear. Sound is typically described in terms of the loudness ( amplitude ) and the pitch ( frequency ) of the wave . Loudness (also called sound pressure level, or SPL) is measured in logarithmic units called decibels (dB). The normal human ear can detect sounds that range between 0 dB (hearing threshold) and about 140 dB, with sounds between 120dB and 140 dB causing pain (pain threshold). The ambient SPL in a library is about 35 dB, while that inside a moving bus or subway train is roughly 85 dB; building construction activities can generate SPLs as high as 105 dB at the source. SPLs decrease with distance from the source.

The rate at which sound energy is transmitted, called sound intensity , is proportional to the square of the SPL. Because of the logarithmic nature of the decibel scale, an increase of 10 dB represents a 10-fold increase in sound intensity, an increase of 20 dB represents a 100-fold increase in intensity, a 30-dB increase represents a 1,000-fold increase in intensity, and so on. When sound intensity is doubled, on the other hand, the SPL increases by only 3 dB. For example, if a construction drill causes a noise level of about 90 dB, then two identical drills operating side by side will cause a noise level of 93 dB. On the other hand, when two sounds that differ by more than 15 dB in SPL are combined, the weaker sound is masked (or drowned out) by the louder sound. For example, if an 80-dB drill is operating next to a 95-dB dozer at a construction site, the combined SPL of those two sources will be measured as 95 dB; the less intense sound from the compressor will not be noticeable.

Frequency of a sound wave is expressed in cycles per second (cps), but hertz (Hz) is more commonly used (1 cps = 1 Hz). The human eardrum is a very sensitive organ with a large dynamic range, being able to detect sounds at frequencies as low as 20 Hz (a very low pitch) up to about 20,000 Hz (a very high pitch). The pitch of a human voice in normal conversation occurs at frequencies between 250 Hz and 2,000 Hz.

Precise measurement and scientific description of sound levels differ from most subjective human perceptions and opinions about sound. Subjective human responses to noise depend on both pitch and loudness. People with normal hearing generally perceive high-frequency sounds to be louder than low-frequency sounds of the same amplitude. For this reason, electronic sound-level meters used to measure noise levels take into account the variations of perceived loudness with pitch. Frequency filters in the meters serve to match meter readings with the sensitivity of the human ear and the relative loudness of various sounds. The so-called A-weighted filter, for example, is commonly used for measuring ambient community noise. SPL measurements made with this filter are expressed as A-weighted decibels, or dBA. Most people perceive and describe a 6- to 10-dBA increase in an SPL reading to be a doubling of “loudness.” Another system, the C-weighted (dBC) scale, is sometimes used for impact noise levels, such as gunfire, and tends to be more accurate than dBA for the perceived loudness of sounds with low frequency components.

Noise levels generally vary with time, so noise measurement data are reported as time-averaged values to express overall noise levels. There are several ways to do this. For example, the results of a set of repeated sound-level measurements may be reported as L 90 = 75 dBA, meaning that the levels were equal to or higher than 75 dBA for 90 percent of the time. Another unit, called equivalent sound levels (L eq ), can be used to express an average SPL over any period of interest, such as an eight-hour workday. (L eq is a logarithmic average rather than an arithmetic average, so loud events prevail in the overall result.) A unit called day-night sound level (DNL or L dn ) accounts for the fact that people are more sensitive to noise during the night, so a 10-dBA penalty is added to SPL values that are measured between 10 pm and 7 am . DNL measurements are very useful for describing overall community exposure to aircraft noise, for example.

Noise is more than a mere nuisance. At certain levels and durations of exposure, it can cause physical damage to the eardrum and the sensitive hair cells of the inner ear and result in temporary or permanent hearing loss , known as noise-induced hearing loss. Hearing loss does not usually occur at SPLs below 80 dBA (eight-hour exposure levels are best kept below 85 dBA), but most people repeatedly exposed to more than 105 dBA will have permanent hearing loss to some extent. In addition to causing hearing loss, excessive noise exposure can raise blood pressure and pulse rates, cause irritability, anxiety , and mental fatigue, and interfere with sleep , recreation, and personal communication. Children living in areas with high levels of noise pollution may suffer from stress and other problems, such as impairments in memory and attention span. Noise pollution control is therefore important in the workplace and in the community.

Noise pollution also impacts wildlife. A wide range of animals, including insects , frogs , birds , and bats , rely on sound for a variety of reasons. Noise pollution can interfere with an animal’s ability to attract a mate, communicate, navigate, find food, or avoid predators and thus can even be an existential threat to vulnerable organisms. The problem of noise pollution is especially serious for marine animals, particularly those that rely on echolocation , such as certain whales and dolphins , and much of the world’s oceans are polluted with chaotic sounds from ships, seismic tests, and oil drills. Some of the loudest and most detrimental sounds in the sea are from naval sonar devices, whose noise can travel hundreds of miles through the water and is associated with mass strandings of whales and dolphins.

Short Essay on Noise Pollution

Noise pollution is a growing problem in today’s society. It is defined as unwanted or excessive sound that can have detrimental effects on the health and well-being of humans and animals. There are many sources of noise pollution, including traffic, construction, industrial activities, and even everyday household items such as lawn mowers and power tools.

The effects of noise pollution can range from minor annoyances, such as difficulty sleeping or concentrating, to more serious health problems like high blood pressure, heart disease, and hearing loss. Children and the elderly are particularly vulnerable to the negative effects of noise pollution.

One of the biggest sources of noise pollution is traffic. Cars, trucks, buses, and trains all contribute to the problem, especially in urban areas. In addition, construction and industrial activities also generate significant amounts of noise. Even activities that we may not think of as being loud, such as leaf blowers and power tools, can contribute to noise pollution.

To combat noise pollution, there are several steps that can be taken. One way is to use sound barriers or insulation in buildings to reduce the amount of noise that enters. This can be especially effective in areas near highways or airports. Another approach is to regulate the use of loud equipment and vehicles, such as implementing quiet hours or stricter emissions standards.

Individuals can also take steps to reduce noise pollution. For example, using earplugs or noise-cancelling headphones can help to protect your hearing. Additionally, you can also reduce your own noise by using quieter appliances and equipment, and by being mindful of the noise you create when outside of your home.

In conclusion, noise pollution is a serious problem that can have negative effects on our health and well-being. To combat it, we need to take a multifaceted approach that includes regulations and individual actions. By working together, we can reduce noise pollution and create a quieter, healthier world.

Long Essay on Noise Pollution

Introduction.

Noise pollution is one of the most commonly overlooked types of pollution. It is often considered a nuisance rather than a serious environmental issue. However, noise pollution can have far-reaching and detrimental effects on both our physical and mental health.

Excessive noise can cause physical pain and damage to our ears. It can also lead to sleep deprivation, anxiety, and cardiovascular problems. In extreme cases, it can even lead to death.

There are a number of sources of noise pollution, including construction sites, traffic, aircraft, and industrial facilities. Even everyday household items like vacuums and blenders can contribute to noise pollution.

Reducing noise pollution will require a concerted effort from both individuals and businesses. Some simple steps that we can all take to reduce noise pollution include: using quieter appliances, turning down the volume on our TVs and stereos, avoiding honking our horns unnecessarily, and wearing earplugs or other forms of hearing protection in noisy environments.

Causes of Noise Pollution

There are many causes of noise pollution. Some of the most common include:

• Traffic : One of the most common and persistent sources of noise pollution is traffic. Whether it’s cars honking their horns, tires squealing, or engines revving, traffic noise can be a real nuisance.
• Construction : Another major source of noise pollution is construction work. The constant sound of jackhammers, saws, and other equipment can be very disruptive, especially if it’s happening near your home or workplace.
• Industrial machinery: Many factories and industrial plants operate 24 hours a day, which means that the noise they generate can be a real problem for nearby residents. The loud humming of machinery can cause headaches, insomnia, and other health problems.
• Loud music : We’ve all been there – trying to enjoy a quiet night at home only to have our peace disturbed by loud music from a neighbor’s party or from a car driving by with its stereo blaring. Unfortunately, loud music is also a form of noise pollution that can damage your hearing over time.

Types of Noise Pollution

There are many different types of noise pollution, all of which can have negative effects on our health. Some common types of noise pollution include:

• Traffic noise : This is one of the most common forms of noise pollution, and it can come from both cars and trucks. Traffic noise can cause hearing loss, stress, and sleep problems.
• Construction noise : Construction sites are often very loud, and the noise can travel for long distances. This type of noise pollution can cause hearing loss, stress, and anxiety.
• Airplane noise : Airplanes produce a lot of noise when they take off and land. This type of noise pollution can cause hearing loss, stress, and sleep problems.
• Industrial noise : Factories and other industrial facilities often produce loud noises. This type of noise pollution can cause hearing loss, stress, and anxiety.

Effects of Noise Pollution

Noise pollution has become a growing problem in many parts of the world. It is a type of environmental pollution that is most commonly caused by loud sounds. Noise pollution can be very harmful to humans and animals. It can cause a variety of health problems, including hearing loss, sleep deprivation, anxiety, and high blood pressure. In some cases, noise pollution can even lead to death.

Noise pollution is most commonly caused by man-made sources, such as construction equipment, loud music, and car horns. However, it can also be caused by natural sources, such as thunder or earthquakes. Regardless of its source, noise pollution can have serious consequences for both human health and the environment.

One of the most serious effects of noise pollution is hearing loss. Exposure to loud noise can damage the delicate hair cells in the inner ear that are responsible for translating sound waves into electrical signals that the brain can interpret. This damage can cause a permanent loss of hearing. In fact, noise-induced hearing loss is one of the most common occupational injuries in the United States. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), about 15% of Americans aged 20-69 have suffered from noise-induced hearing loss.

In addition to causing hearing loss, noise pollution can also lead to other health problems, such as sleep deprivation and anxiety. Loud noises can disrupt normal sleep patterns and make it difficult to get a good night’s rest.

Solutions to Reduce Noise Pollution

There are many ways to reduce noise pollution. Some solutions require changes at the individual level, while others need to be implemented at the government or organizational level.

Individuals can take steps to reduce noise pollution in their everyday lives by being aware of the sources of noise pollution and taking action to minimize exposure. For example, turning off electronics when not in use, using headphones when listening to music or watching TV, and avoiding loud environments when possible.

Governments and organizations can also play a role in reducing noise pollution. They can pass laws and regulations to limit noise from certain sources, such as construction sites and vehicles. They can also create public awareness campaigns to educate people about the effects of noise pollution and how to reduce it.

Benefits of Reducing Noise Pollution

There are many benefits to reducing noise pollution. One benefit is that it can help reduce stress levels. Studies have shown that exposure to high levels of noise can increase stress hormone levels, which can lead to health problems such as high blood pressure, heart disease, and stroke.

Another benefit of reducing noise pollution is that it can help improve sleep quality. Exposure to loud noise can disrupt sleep, causing people to wake up feeling tired and unrested. This can lead to a number of health problems, including fatigue, headaches, and difficulty concentrating.

Reducing noise pollution can also help protect the environment. Noise pollution can disturb wildlife and cause them to flee their habitats. This can have a negative impact on the ecosystem as a whole. In addition, noise pollution can cause hearing loss in humans and other animals.

Examples of Successful Noise Reduction Strategies

1. One of the most effective noise reduction strategies is to use sound-absorbing materials in order to dampen noise. This can be done by installing acoustic panels in strategic locations or using rugs and carpets to help muffle sounds.

2. Another way to reduce noise pollution is to create buffer zones between noisy areas and more sensitive areas. This can be done by planting trees and shrubs, erecting barriers, or constructing sound walls.

3. It is also important to limit the sources of noise whenever possible. This may mean banning loud music in certain areas, enforcing quiet hours, or limiting the use of motorized vehicles.

4. Finally, effective communication and education are critical for reducing noise pollution. By raising awareness about the problem and its solutions, people can be empowered to take action to reduce noise in their own communities.

Noise pollution can be a serious problem in our cities and towns, but it is something that we all have the power to reduce. By taking small steps, like avoiding loud music or asking for quieter routes when travelling, we can make a big difference in limiting noise pollution. We should also remember that not only do we need to take preventative measures against noise pollution, but also support those who are already affected by its consequences. With everyone’s help, noise pollution can become a distant memory.

Noise Pollution – 10 Lines, Short & Long Essay For Children

Key Points To Remember When Writing An Essay On Noise Pollution For Lower Primary Classes

10 lines on noise pollution for kids, a paragraph on noise pollution for children, short essay on noise pollution in english, long essay on noise pollution for kids, how to reduce noise pollution, what will your child learn from an essay on sound pollution.

The sounds produced in nature don’t have an irritating effect on our minds. For example, imagine birds singing, waves crashing, or wind blowing. All these sounds are comfortable to our ears. But the industrial era has introduced us to high-powered machines that produce higher decibel sounds. These machines are all around us, and they cause noise pollution. When writing an essay on noise pollution for classes 1, 2 & 3, we should introduce a background like this to set the tone. In this article, we will try to write an essay on noise pollution.

You must provide basic and simple information when writing an essay for lower primary classes. Please do not indulge in too many details because it can be difficult for kids to learn. Here are some key points on how to write an essay on noise pollution for lower primary classes:

• Explain the meaning of noise. 
• Explain what noise pollution is.
• Add a paragraph about the causes of noise pollution.
• Add a paragraph about the adverse effects of noise pollution.
• Add a paragraph about how to prevent noise pollution.
• You may even add some interesting points for kids to keep them engaged in the essay.
• Do not write bulky paragraphs. Short and sharp sentences should do the trick.

Noise pollution is an underrated form of pollution. The severity of this issue is still unnoticed because it does not cause any immediate health concerns. However, authorities have become a lot more aware today and organise public awareness events to educate people about the harmful effects of noise. Here is an essay for classes 1 and 2 depicted through 10 simple lines:

• The decibels found in nature are much lower than what we experience today.
• When we introduce a loud foreign source into the environment, we cause noise pollution.
• Noise pollution is caused by noisy machines, loudspeakers, vehicles, and other objects producing sound at high decibels. Even rock concerts are a cause of noise pollution.
• Like air and water pollution, noise pollution also adversely affects our health.
• The World Health Organisation recognises noise pollution as a major health hazard.
• The European Environment Agency also monitors the effects of noise pollution on Europeans. They have stated that noise pollution is responsible for a lot of premature deaths.
• When continuously subjected to noise pollution, a person can develop several chronic issues.
• Noise pollution can lead to ADHD and other dangerous health hazards. Initially, the problem may not seem much, but it can lead to bigger problems over time.
• Noise pollution also harms other living beings such as birds, whales, dolphins, bats, etc.
• Noise pollution can be reduced by minimal use of loud machines, controlled loudspeakers, refraining from using horns, etc.

Reading about noise pollution is crucial to know about its negative impacts. Here is how to write a noise pollution essay in 100 words:

Pollution means introducing contaminants into the atmosphere that cause adverse change. When it comes to noise pollution, the pollutants are sources of loud noise, and the negative change is the jacking up of natural decibels. People constantly subjected to noise pollution develop certain health issues like ADHD, irritation, migraine, anxiety, etc. It’s not just humans who suffer the wrath of noise pollution; animals are severely affected by it. Similarly, several birds risk being endangered because their reproduction rate is adversely affected when they dwell close to an environment with noise pollution. We can reduce noise pollution by educating people on the subject and introducing a strict penal system in case of breach of regulations.

Sometimes, teachers ask kids to write a short essay about noise pollution in primary classes. Here’s an example that you can refer to:

We know the adverse effects of water, air, and soil pollution because the hazards show themselves instantly in many cases. But it is difficult to imagine the damage caused by noise pollution because it is not something we can see. It is crucial to note that noise pollution impacts millions of people daily. The commonly reported problem due to noise pollution is hearing loss. Not everyone can afford high-end hearing devices, so it gets tough for people from lower-income strata. Apart from this obvious concern, noise pollution is known to cause hypertension, sleep disturbances, stress, and heart diseases. Thus, finding ways to reduce the overall noise level in all spaces becomes crucial. This can help avoid many health issues and keep everyone’s mental health at par. However, it requires more than just government policies to curb noise pollution — everyone has to put individual efforts.

As the kids reach higher grades at the primary level, they will be asked to write an elaborate essay. Now, let’s structure an essay for class 3:

High noise regions are areas close to airports, railway stations, construction sites, etc. Researchers have also studied the adverse effects of noise pollution on several animals. It has been observed that caterpillars’ hearts beat faster when they are exposed to loud noises. Similarly, it is reported that bluebirds have fewer chicks when exposed to high decibel sounds. We must not forget the natural utility of an atmosphere with clean sounds. Several animals rely on their ability to read sounds from their prey to hunt them. When noise pollution contaminates the wave frequency, it becomes difficult for these predators to survive, which is bad for the ecosystem.

Noise pollution and its impacts are not limited to the land. However, it is pertinent to note here that we are also responsible for noise pollution in the water bodies apart from water pollution.

Causes Of Noise Pollution

Noise pollution is primarily caused by machines that produce high decibel sounds. The machines that use powerful motors are one of the primary causes of noise pollution. In an urban setup, the sound from vehicle engines and horns causes noise pollution. Aircraft and trains are the primary sources of noise pollution for people living near airports and railway stations. Additionally, construction sites have also been identified as one of the causes of noise pollution.

Effects Of Noise Pollution On Human Health

People from all walks of life are susceptible to the adverse effects of noise pollution. Here are some of the impacts of noise pollution on human health:

• Children who live close to loud noise regions sometimes have stunted brain growth. These children often suffer from memory loss, ADHD, reading difficulties, etc.
• Adults have been reported to suffer from migraine when subjected to noise pollution.
• Anxiety, stress disorder, and irritability are quite common among people close to noise sources.

Effect Of Noise Pollution On Animals

Today, there are so many ships that it is hard to imagine a peaceful ocean. Similarly, all the countries are into offshore drilling, producing excessive noise levels. Among all the marine animals, whales and dolphins are the ones that rely on sound frequencies to catch their prey. Hence, they are the most affected by noise pollution in the sea. We know how important echolocation is for marine animals. Here are some adverse effects of noise pollution on animals:

• Many predators use echolocation to communicate and feed. Unusually, loud noises interfere with their sound ecosystem, which is bad for their survival.
• Sound navigation and ranging are used to locate objects underneath the water’s surface, so appropriate safety measures have been taken. Sonar devices send high-frequency sound waves to see if they bounce off an object. If the sound reflects off the surface of an object, its location is pinpointed. The technology is remarkable, but it is detrimental to marine animals because it works exactly like echolocation. Sonar sounds can achieve a peak loudness of 235 dB, which is magnanimous. When whales use echolocation, they are often interfered with by sonar waves, which impairs them.
• Noise pollution is known to have caused alteration in the feeding behaviour of blue whales and dolphins.

We have talked about the negative impacts of noise pollution and its technicalities. Governments have also accepted this issue and implemented ways of reducing noise pollution.

The government has mandated that new houses be built according to the guidelines, which provides for installing soundproof walls if the building is coming up near a high noise region. The government is also running awareness campaigns so people would actively take care of noise pollution. Lastly, the governments have pledged to plant more trees, known to reduce noise pollution by quite a margin.

This noise pollution composition will teach your child the art of writing a structured article. Additionally, this article has plenty of information on noise pollution, which can be used as a teaching module for kids. Your child will learn how to cover the topic by going through the short and long paragraphs.

Noise pollution is a menace we all need to fight to save the environment. We hope this article works as an eye-opening guide for you to take the necessary steps toward curbing this common enemy.

One of the main effects of noise pollution is its impact on human health. Prolonged exposure to high levels of noise can lead to a range of health problems, including hearing loss, stress, sleep disturbances, and cardiovascular issues. Studies have shown that noise pollution can also have a negative impact on mental health, leading to increased levels of anxiety, depression, and irritability. In addition, children exposed to high levels of noise pollution may experience difficulties in learning and cognitive development.

Noise pollution can also have detrimental effects on wildlife. Many animals rely on their sense of hearing for communication, navigation, and hunting. Excessive noise can disrupt these activities, leading to changes in behavior, habitat loss, and even death. For example, marine mammals such as whales and dolphins rely on sound for communication and navigation, and underwater noise pollution from ships and sonar can interfere with their ability to find food and mates.

In addition to its effects on human health and wildlife, noise pollution can also have negative impacts on the environment. Excessive noise can disrupt ecosystems, leading to changes in plant and animal populations. It can also contribute to soil erosion and water pollution, as noise can cause vibrations that disturb the natural balance of the environment.

There are several ways to address noise pollution and mitigate its effects. One approach is through urban planning and design, such as creating buffer zones between noisy areas and residential areas, and implementing noise-reducing measures in buildings and infrastructure. In addition, regulations and policies can be put in place to limit noise levels from sources such as vehicles, machinery, and construction activities.

Individuals can also take steps to reduce noise pollution in their own lives, such as using noise-canceling headphones, turning down the volume on electronic devices, and choosing quieter modes of transportation. By raising awareness about the impacts of noise pollution and taking action to reduce it, we can create a healthier and more peaceful environment for ourselves and future generations.

Essay on Noise Pollution in 1000-1500 Words

Noise pollution is a growing concern in today’s world, as the hustle and bustle of urban life continues to increase. From the honking of cars to the blaring of music, noise pollution is becoming a pervasive issue that is affecting the health and well-being of individuals worldwide. In this essay, we will explore the causes and effects of noise pollution, as well as potential solutions to mitigate its impact on society.

First and foremost, it is important to understand what noise pollution is and how it differs from other forms of pollution. Noise pollution is defined as any unwanted or disturbing sound that interferes with normal activities and disrupts the balance of human and animal life. This can include loud noises from traffic, construction sites, industrial machinery, and even recreational activities such as concerts and sporting events. While noise pollution may not always be visible like air or water pollution, its effects can be just as harmful to both the environment and human health.

There are several factors that contribute to noise pollution, with urbanization and industrialization being the primary culprits. As cities continue to grow and expand, so too does the amount of noise generated by human activities. Traffic congestion, construction projects, and the constant hum of machinery all contribute to the cacophony of sounds that permeate urban environments. In addition, the rise of technology and electronic devices has also played a role in increasing noise pollution, as people are constantly surrounded by the buzz of cell phones, televisions, and other electronic gadgets.

The effects of noise pollution on human health are well-documented and can have serious consequences if left unchecked. Prolonged exposure to high levels of noise can lead to a variety of health problems, including hearing loss, sleep disturbances, cardiovascular issues, and even mental health disorders such as anxiety and depression. In fact, the World Health Organization has identified noise pollution as a major environmental health hazard, with studies showing that it can have a significant impact on overall quality of life and well-being.

In addition to its effects on human health, noise pollution can also have detrimental effects on the environment and wildlife. Animals that rely on sound for communication and navigation, such as birds and marine mammals, can be particularly vulnerable to the disruptive effects of noise pollution. For example, underwater noise from ships and sonar devices can interfere with the communication and feeding patterns of marine animals, leading to disruptions in their natural habitats and potential population declines.

Given the far-reaching impacts of noise pollution, it is imperative that steps be taken to address this issue and mitigate its effects on society. One potential solution is the implementation of noise regulations and guidelines to limit the amount of noise generated by human activities. This can include restrictions on construction hours, noise limits for vehicles and machinery, and zoning regulations to separate noisy industrial areas from residential neighborhoods.

Another approach to reducing noise pollution is through the use of soundproofing and noise barriers to minimize the transmission of sound from sources to receptors. This can include the installation of soundproof windows and doors in buildings, as well as the construction of physical barriers such as walls and fences to block out noise from highways and other sources. In addition, the use of noise-reducing materials and technologies in the design of buildings and infrastructure can help to minimize the impact of noise pollution on surrounding communities.

Education and awareness are also key components in addressing noise pollution, as many people may not be aware of the harmful effects of excessive noise on their health and well-being. By raising awareness about the issue and promoting sound conservation practices, individuals can take steps to reduce their own contribution to noise pollution and advocate for policies that protect the environment and public health.

In conclusion, noise pollution is a significant environmental and public health issue that requires immediate attention and action. By understanding the causes and effects of noise pollution, as well as implementing solutions to mitigate its impact, we can create a more peaceful and sustainable environment for future generations. It is up to all of us to take responsibility for our actions and work together to reduce noise pollution and create a healthier, quieter world for all.

• Sound Pollution Essay

Essay on Sound Pollution

With the increase in population, the pollution causes and the types are only increasing around the world. Many kinds of pollution are causing harm to the environment, like air pollution, water pollution, land pollution etc. The most recent one being sound pollution also called noise pollution that is only rampantly increasing. In a country like ours where there is rapid urbanization, the cities have shown a massive increase in noise pollution. Whose effects have created an impact on the health conditions of the residents as well? In this article for a sound pollution essay in English, we will learn what constitutes it and who it impacts. The formats discussed below are a long essay on sound pollution and a short essay on sound pollution, both of which are helpful for students learning.

Long and Short Sound Pollution Essay in English

Short sound pollution essay.

This essay on sound pollution is a brief explanation of the meaning and reasons that contribute to the cause.

Sound Pollution or noise pollution is now a major concern especially in populous places and metro cities in India is a recent phenomenon and an impactful one at that. While we are aware of other kinds of pollution like air, water and land which is harming the natural bodies of the environment. And slowly affecting the ecosystem leading to humans.

Noise pollution on the other hand has no such significant effects on the environment or the natural bodies of the planet. It directly harms the residing beings that are humans and animals.

All living beings have a certain threshold to certain types of sound which can fall under the range of 0 decibels to 120 decibels. And when a human ear is exposed to sounds ranging above 90 decibels, the damage is caused. The damaging frequency of sound can be from honking in traffic or from loud music at parties. The damage is concerning either way.

Even though in India, laws for no loud music in parties or large gatherings after 10 pm are enforced, the health effects should be also considered and strict road laws must be applied. It can lead to mental illnesses, can turn a person deaf and even high blood pressure. We must all do our bit in controlling what we can and not contribute to the noise whether indoors or outdoors.

Long Sound Pollution Essay

In this type of essay on sound pollution, the reasons and effects are mentioned in detail.

Sadly all the causes of pollution are man-made like air pollution which is because of harmful emissions from factories and industries built by humans for their benefit. Similarly, the reason for sound pollution is also human-made and unwanted sound distribution is called noise. This even though not deliberately caused, has been seen as a major cause for many human health problems. It is not a lethally affecting cause, but the consequences of this kind of pollution on health are nevertheless problematic and difficult.

An audible sound can be of varying frequencies and pitches. And the measurement unit is decibels which are denoted as “dB”. There are various threshold levels for humans ranging from 0dB to 120dB. Not all ranges are audible to every living being. Any form of sound that falls under this range is audible to the human ear. But some sounds are considered noise when they are damaging to the ear.

The range that is audible to humans is A-weighted decibels that can also be written as dBA. And anything below 70dBA is the optimal range for the human ear. Any magnitude or intensity above it, especially sound ranges that lie above 85dB, is very damaging to the human ear. This damage is then not just limited to just the ear, other abilities are also affected.

Many things contribute and add to the causes of noise pollution. There are many reasons for the increasing sound pollution from various sources that can be categorized as indoor and outdoor sources.

Indoor sources are within our own homes or in the noise from the neighborhood. The noise from electronic gadgets, household utensils, musical instruments, transistors, generators and inverters and speakers. The other factor of the indoor environment is that of an event or a wedding function where loud music is played unabashedly that does no good to anybody.

Outdoor sources are industries, which is a leading source of usage of heavy machines, exhaust fans and mills that cause unwanted noise. Industrialization is also a double-edged sword. Industries are located in the outskirts so the nearby villagers and towners are mostly affected. Construction sites and mining sites also produce a lot of unwanted noise due to the machines used for building and excavating. The other cause of outdoor noises is from roads due to vehicles. Especially in cities where everyone has their mode of transportation and traffic congestion is also no less. And honking in those situations is the major contributor to sound pollution. Railways, aircraft and bursting of crackers and other fireworks also add to the cause.

These reasons have a major impact on living beings. It leads to hearing impairment and in many cases hearing loss. The eardrums in the inner ear cannot tolerate the constant exposure to loud noises. When one is continuously exposed to such high pitch sounds, the blood levels elevate and cause high blood pressure or hypertension.

This further causes anger issues, tiredness and fatigues the body leading to sleeping disorders. Which in the long run may also cause mental illness like anxiety and depression. The raised blood levels also result in heart diseases and a constant increase in stress levels.

Preventing is a personal responsibility and we should be accountable for our actions. The best way is to abstain from using loudspeakers which are helpful for others as well. One can also install soundproof systems in buildings that generate loud noise like industries and hospitals. Honking must be limited and not practiced irresponsibly.

Important Tips to write an effective Essay  

Brainstorm and Plan - Before you start writing, it's usually a good idea to gather your thoughts. Try to come up with as many ideas for your essay as possible based on your question or topic. When it comes to writing the essay, making a proper writing outline will really save you time. If you get stuck at first, scribble down a few thoughts and the rest will likely flow.

Prepare and Make a Structure - Outlining your essay and gathering proof resources are both part of the preparation step. Examine the outcomes of your brainstorming session. Extract the concepts that are most important to the success of your thesis, and then organize them in a logical and progressive order. This is where you'll include your essay's structure and content. If you're looking for empirical proof or supplementary citations, start looking now.

Drafting - This is the stage of the essay writing process where you compose the early draft. Remember that nothing has to be perfect; this is your first version, not your final plan, so allow yourself to make mistakes.

Revision - You've completed the essay, but you're not finished yet. Look through what you've written again for any errors or typos. Check for mistakes in language, punctuation, and spelling. You can't always rely on spell check to catch all of your mistakes. Sometimes you can misspell a word but it will still be a word, such as when you misspell "from" as "form."

Sources of Sound Pollution

Despite the fact that sound pollution is neither dangerous or lethal to people in any way, it is nonetheless an extremely destructive sort of pollution. All causes of noise pollution are man-made. Noise from different transportation systems, particularly motor cars, is one of the most prevalent and hazardous sources. Sound pollution is caused by increasing traffic congestion, the sheer quantity of vehicles on the road, and noise from unnecessary honking, among other things. Industrial operations are another important cause of noise pollution. Factories, printing presses, mills, and other businesses all contribute to the area's noise pollution. There are literally thousands of different forms of noise pollution, such as loudspeakers, roads, fireworks, home sounds, and agricultural operations, all of which are damaging and contribute to noise pollution in some way.

Sound pollution is indeed a cause of concern like other pollution but the major factor to consider here is it can be easily controlled. We must begin at home and start placing the utensils carefully. And induce sound controllers in the generator or inverters this will prevent the children and the old people at home to be safe from ear damage. The other major way is to not honk unnecessarily on roads. Creating awareness about such problems and the damages they caused to others and also providing them with the way to handle such problems brings effective changes.

FAQs on Sound Pollution Essay

1. What is the cause of Noise Pollution?

At the same time as the world is turning to technology for comfort, it is damaging us. Industry, no matter how large or little, contributes to noise pollution. Compressors, exhaust fans, generators, and other machinery make a lot of noise. 

Similarly, an increase in the usage of vehicles is a key contributor to pollution. It includes not just autos, but also other modes of transportation such as aircraft, buses, bicycles, trucks, and more. People honk incessantly in traffic and listen to loud music while driving, causing excessive noise. Furthermore, social activities such as weddings, parties, and religious services held in places such as clubs, pubs, temples, halls, and other venues cause a great deal of annoyance in residential neighborhoods. Furthermore, noise is produced by construction operations such as mining, the construction of flyovers, bridges, and other structures.

2. What are the damaging impacts of Noise Pollution?

Noise pollution has a significant influence on the lives of living beings, despite the fact that it is rarely discussed. Noise pollution, for instance, causes a variety of hearing impairments. High amounts of noise harm the Eardrums and can possibly induce hearing loss. Similarly, it lowers ear sensitivity to noises that the human body needs to regulate our body's rhythm.

Furthermore, it has an impact on our mental health. It may not be immediately apparent, but it has a long-term effect on our behavior. You may have weariness and even migraines if your sleep is disrupted or if you have persistent headaches as a result of excessive noise. Noise pollution has an influence on animals as well as humans. When pets hear a loud noise, they may become angry or fearful. To conclude, we must raise awareness about the dangers of noise pollution. We must also urge them to choose methods that do not add to noise pollution. We will undoubtedly be able to minimize noise pollution to a significant amount if everyone starts doing the same on a personal level.

Introduction.

Do you get irritated when someone honks their car horn while waiting for the traffic signal to turn green? Will you be able to concentrate on your work/studies when heavy construction is taking place near your house and the drilling sound deafens you? These are some of the instances of noise pollution, and we will be discussing more in this noise pollution essay.

Causes of Noise Pollution

There are various factors that cause noise pollution in the environment, and we will understand them through this short essay on noise pollution. We know that technology has eased the life of humans through grinders, compressors, televisions, generators etc., but we are not aware that this same technology is ruining our health. Along with these machines, there are also cars, bikes, buses, trains and aeroplanes that produce a large amount of noise. We will see how this creates pollution through this noise pollution essay.

People unnecessarily use horns, and the long siren disturbs other people. Besides, people play music at a loud volume while travelling in cars or buses. Due to this, we put others in an inconvenient position. It is only required to think of the commotion that happens during weddings and other festivals and how it causes a nuisance to those residing nearby to understand the seriousness of the matter. The noise pollution essay in English is, therefore, an attempt to throw light on this issue.

Ways to Reduce Noise Pollution

Noise pollution is a serious concern, and hence, we must try to prevent it. But before we see how it can be controlled, we will see its effect on us in this short essay on noise pollution. Noise pollution causes hearing problems if we get exposed to a high volume of sounds continuously. It also has the potential to damage our eardrums, resulting in permanent loss of hearing.

Moreover, it disturbs our state of mind, and we might experience stress, tension, loss of sleep etc., thus affecting our psychological health. All these reasons point out that noise pollution can be dangerous and we must follow certain measures to prevent it.

First of all, we must be responsible for not honking unnecessarily. If strict actions are taken against the violators of this rule, we can reduce noise pollution to some extent. Besides, installing soundproof walls and windows in houses, buildings and flyovers can also help in bringing down the noise level.

Planting trees is another effective measure as we can reduce the noise from travelling from one place to another. So, children can write an essay on noise pollution 150 words by taking important points from the noise pollution essay in English and thus creating awareness regarding the issue.

Frequently Asked Questions on Noise Pollution Essay

What are the effects of noise pollution.

Noise pollution creates many health issues in humans and affects their hearing ability. Hypertension, stress, irregular sleep patterns and irritation are its other effects. Noise pollution also harms wildlife and marine life as it impairs their listening abilities.

How to reduce noise pollution?

People can wear earplugs or earmuffs while working in factories that produce a high level of noise daily. Car horns must not be used needlessly and playing loud music on public transport should be banned. Planting more trees can also reduce noise pollution to some extent, as vegetation helps in the reduction of sound intensity.

It is considered as the environmental pollution caused in the environment by the excess level of noise through many sources. Noise pollution is also known as the noise disturbance. Excessive noise is harmful to the health and cause imbalance to the human or animal life. It has been a massive environmental issue in India which needs a proper attention to be solved however it is less dangerous than the water, air and soil pollution. Outdoor noise is hugely caused by the sources like machines, transportation systems, poor urban planning (construction of side-by-side industrial and residential buildings), etc. Indoor noise sources are household machines, building activities, loud music, etc. The most common impairment caused by the noise pollution is the permanent hearing loss due to ear drum damage.

Noise Pollution Essay 2 (150 words)

Normal level of the sound necessary to maintain the daily lives however undesired sound or noise which is not tolerated by the people, animals or plants causes noise pollution in the environment. Noise is commonly called as the unwanted sound created by many industrial or non-industrial sources used in the daily life in our surrounding. High level sound creates unpleasant effects and discomfort to the health especially to the ears.

Unwanted sound generally interferes with the daily routine activities like sleep in night, conversation, hearing ability, feeling of well being, etc. Water animals also affected by the noise pollution created by the noise of submarines and big ships in the ocean. Forest animals have been affected to a great extent due to the chain-saw operations (create extreme noise) by timber companies. Common sources of the noise pollution are household gadgets, transport vehicles, jet planes, helicopters, industrial machines, etc. According to the World Health Organization, industries must limit their sound production by 75 dB.

Noise Pollution Essay 3 (200 words)

Noise pollution the pollution caused by the high and unsafe level of noise in the environment causes lots of health disorders to the human beings, animals and plants. Common problems caused by the noise pollution are stress related illnesses, anxiety, communication problems, speech interference, hearing loss, lost productivity, sleep disruption, fatigue, headache, irritability, nervousness, weakness, reduce sensitivity to sound which our ear receive to maintain body rhythm, etc. It causes gradual impairment to the hearing ability over a long period of time. Continuous exposure to high level sound causes permanent damage to the eardrum.

High level of the noise causes huge nuisance, injuries, physical trauma, bleeding around brain, large bubbles in organs and even death to the marine animals specially whales and dolphins as they use their hearing ability to communicate, find food, defend and survive in water. Source of noise in the water is navy submarine’s sonar which can felt around 300 miles away. The consequences of the noise pollution are more dangerous and worrying in the near future.

There are many preventive measures of the noise pollution, some are like promoting soundproof rooms construction in the industries, industries and factories should be away from the residential building, repairing of motorbikes having damaged exhaust pipes, ban of noisy vehicles, airports, bus, railway stations and other transport terminals should be far from the living places, declaring silence zones near educational institutes and hospitals, allowing more vegetation along with roads and residential areas in order to reduce noise pollution by absorbing sound.

Noise Pollution Essay 4 (250 words)

Noise pollution caused by the high level of unwanted sound in the environment which causes pain. Some of the main sources of the noise pollution like noise generated by the road traffic, air craft noise, railroads noise, noise generated by the construction (of buildings, highways, city streets, flyovers, etc), industrial noise, noise created in home on daily basis (due to electrical home appliances, plumbing, generators, air conditioners, boilers, fans, etc), and noise from consumer products (like household equipments, kitchen appliances, vacuum cleaners, washing machine, mixer, juicer, pressure cooker, TV, mobile, dryer, cooler, etc).

In some countries (highly populated countries like India, etc) poor urban planning also plays vital role in the noise pollution as this planning includes the construction of congested houses having large families in small space (causing fight for parking, fights for basic requirements, etc) lead to the noise pollution. New generation people play music in full volume and dance for late night causing lots of physical and mental disturbances to the neighbors. High level of noise causes loss of normal person’s ability to hear properly. High level of noise slowly affects the health and acts as slow poison.

It hugely affects the wildlife, lives of plants, and human beings. Normally, the ability of our ear is to accept the only certain range of sounds without making any damage to the ear. However, our ear cannot bear the regular exposure to loud levels of noise and get damage to the ear drums which results in the temporary or permanent loss of hearing. It also causes other disorders like sleeping disorders, fatigue, weakness, cardiovascular issues, stress, high blood pressure, communication problem, etc.

Noise Pollution Essay 5 (300 words)

It has become so dangerous that it can compared to the other most dangerous problems like cancer, etc in which slow death is sure. Noise pollution is the dangerous gift of modern living style and increasing level of industrialization and urbanization. If regular and effective actions not taken to control, it can very serious to the future generations. Noise pollution the pollution caused by the noise due to the increased level of unwanted sound in the environment. It is a big potential hazard to the health and causes huge level of communication problems.

High level of noise brings irritation in the behavior of many people especially diseased, old people and pregnant women. Unwanted sound causes deafness problem and other chronic disorders to the ear like damage to the ear drum, ear pain, etc. Sometimes high sound music pleases the listeners however irritates other people. Any undesired sound in the environment is injurious to the health. Some of the sources participating highly in the noise pollution are industries, factories, transportation, traffic, aeroplane engines, train sounds, home appliances, construction, etc.

The noise level of 60 db considered as the normal noise however, noise level of 80 db or above become physically painful and harmful to the health. Cities having high noise quantum are Delhi (80 db), Kolkata (87 db), Bombay (85 db), Chennai (89 db), etc. Limiting the amount of noise to a safe level has become very necessary for the life on the earth as undesired noise affects the health of human beings, plants and animals too. It is possible through the general awareness among public about the noise pollution, its main sources, it’s dangerous effects, as well as all the possible preventive measures to get prevented from the noise pollution.

Noise Pollution Essay 6 (400 words)

It caused by the noise when the level of noise gets increased than the normal level in the environment. Excessive amount of noise in the environment is unsafe for the living purpose. Unpleasant sound causes various disturbances in the natural balance. High volume noises are unnatural and create difficulty in escaping those generated noises. In such a modern and technological world, where everything is possible through the electrical appliances at home or outside the home, the risk of noise has increased to a great extent.

Increasing the demand of urbanization and industrialization in India is causing major exposure of people to the unwanted sounds. Understanding, planning and implementing strategies to get prevented from the noise pollution has necessary to curb within time. The sounds we make in our everyday life like loud music, unnecessary use of television, phone, traffic, dog barking and etc noise creating sources have become part of the urban culture as well as most disturbing things causing headache, sleep disturbances, stress, etc. Those things causing disturbance to the natural rhythm of life called as dangerous pollutant. Following are the causes or sources and effects of the noise pollution:

• Industrialization is putting our health and life at risk because all the (big or small) industries are using big machines producing high pitch sound in large amount. Other equipments (compressors, generators, exhaust fans, grinding mills) used in the factories and industries also produces big noise.
• Regular social events like marriages, parties, pub, club, disc or place of worship, temples, etc create nuisance in the residential area.
• Increasing transportation in the cities (vehicles, aeroplanes, underground trains, etc) produces heavy noise.
• Regular construction activities (including mining, bridges, building, dams, stations, roads, flyovers, etc) involve big equipments creating high level of noise.
• Use of household appliances in our daily life is also the main reason noise pollution.
• Noise pollution causes various hearing problems (damage to ear drums and loss of hearing) because of the unwanted sound.
• It reduces ear sensitivity to the sounds required to regulate body rhythm.
• Noise pollution affects the psychological health and causes the occurrence of aggressive behavior, sleep disturbance, stress, weakness, fatigue, hypertension, cardio-vascular diseases including other severe and chronic health issues in later life.
• It creates communication problems and lead to misunderstanding.
• Affects wildlife and makes pets more aggressive.

Preventive Measures:

General awareness should increased among people and all the rules should followed seriously by everyone in order to control the unsafe sound level in the environment. Unnecessary use of things generating high pitch sound should reduced in the home or outside the home like clubs, parties, bars, discos, etc.

Essay 7 (800 words)

Noise pollution the pollution caused by the various noise sources whether by the industrial or non-industrial affecting the human beings, plants and animals health in many aspects. Regularly increasing level of the noise pollution is keeping the lives of people of present generation and coming generations at high risk. I have discussed below the sources, effects, legal aspects control noise pollution and conclusion of the noise pollution.

Following are the sources of noise pollution

The level of noise pollution has increased a lot in India by the urbanization, modern civilization, industrialization, etc. The spread of noise caused by the industrial and non-industrial sources. Industrial sources of noise include the use of big machines of high technologies working at high speed and high level of noise intensity in the various industries. Non-industrial sources of noise include noise created outside the industries such as through the transport, vehicles traffic and other means by people. Non-industrial source of noise can be natural or man made. Some of the industrial and non-industrial sources of noise pollution mentioned below:

• Noise created by the low flying military aircraft has also added noise pollution to the environment to a great extent.
• Road traffic noise is increasing day by day in the city because of the motors and exhaust system of vehicles like trucks, buses, autos, motorcycles, personal cars, etc. Tall buildings in the cities cause noise to resound in that area for some time.
• Industrial noise created by the manufacturing plants because of the use of motors, compressors, fans, etc.
• Construction noises created by the construction of tall buildings, roads, highways, city streets, etc through the use of pneumatic hammers, bulldozers, air compressors, dump trucks, loaders, pavement breakers, etc.
• Rail roads noise (from locomotive engines, whistles, horns, switching or shunting operations in the rail yards) are also very effective in the creating high level of noise pollution as they create peak level of noise of around 120 dB to the 100 feet distance.
• Noise created in the building because of the plumbing, generators, boilers, household equipments, music, air conditioners, vacuum cleaners, kitchen appliances, fans, and other noisy activities in the neighborhood.
• Another source of noise pollution is the use of variety of fire crackers (high sound generating) during the festivals and other family occasions.

Following are the effects of noise pollution

Noise pollution highly affects the health of human beings, animals and properties. Some of mentioned below:

• Increasing noise pollution day by day is decreasing the efficiency and quality of work of human beings.
• Noise pollution reduces concentration level as high level of noise causes fatigue and tiredness.
• Hugely affects the pregnant women and cause irritation and abortion.
• Causes various diseases (high blood pressure and mental illness) to the people because it disturbs the peace of mind.
• High level of noise decreases quality of work and thus causes lack of concentration level.
• It may cause temporary or permanent deafness because noise level of 80 to 100 db is unsafe for the people.
• It also damage historical monuments, old buildings, bridges, etc because it weakens the structure by creating dangerous waves which struck to the walls.
• Animals lose control on their mind and can be more dangerous because high level noise damage their nervous system.
• It also affects the plants and causes poor quality crops production.

Following are legal aspects to control noise pollution

• Constitution of India guarantees right to life, right to information, right to religion and noise.
• Section 133 empowers human being to remove a public nuisance on a conditional or permanent order.
• It is Control Rule 2000 under Environment Protection Act 1996 involves controlling the growing problem of noise pollution.
• Factories Act Reduction of Noise and Oil of Machinery limits for noise exposure in the work zone.
• Motor Vehicle Act involves the use of horn and change of fault engines.
• Indian Penal code deals with the health and safety issues caused by the noise pollution. One can penalized under law of torts.

Increasing level of noise pollution has created the urgent need of general awareness about the sources, effects and preventive measures of the noise pollution. High level of noise should prohibited in the areas like working places, educational institutes, residential areas, hospitals, etc. Young children and students should motivated to not get involved in the high sound producing acts like use of high sound generating equipments and instruments on the occasions. Use of high level sound generating fire crackers should reduced during the occasions like festivals, parties, marriages, etc. Subjects related to the noise pollution should added into textbooks and activities can organized in the schools like lectures, discussion, etc so that new generations can more aware and responsible citizens.

Long-term exposure to traffic noise and air pollution linked to increased infertility risk

Traffic Noise and Air Pollution Could Be Hurting Your Fertility: New Study Uncovers Surprising Risks for Men and Women.

A recent BMJ study explores the associations between long-term exposure to road traffic noise, air pollution, and infertility in men and women.

Risk factors for infertility

Infertility is a major global health problem that is defined as a lack of conception after unprotected and regular sexual intercourse for one year. Infertility has also been associated with long-term adverse health effects, including an increased risk of stress, anxiety, and depression.

Several risk factors for infertility are similar between both men and women, of which include advanced age, tobacco and alcohol use, chronic conditions and diseases, and obesity. Exposure to air pollution, pesticides, and ionizing radiation may also increase the risk of infertility.

Previous research has shown that particulate air pollution is negatively correlated with sperm count, motility, and morphology. Exposure to air pollution can also reduce the success rate of fertility treatment in women.

Like air pollution, road traffic noise has been associated with various chronic diseases. Noise activates the autonomic nervous system and hypothalamic-pituitary-adrenal axis, thereby inducing a stress response.

Noise pollution can cause sleep disruptions which, coupled with stress, can negatively impact reproductive function. Nevertheless, there remains a lack of research examining the impact of noise on fertility.

About the study

The current nationwide prospective cohort study was conducted in Denmark and comprised 526,056 men and 377,850 women between 30 and 45 years of age. All men and women included in the study were married or cohabiting, had fewer than two children, and were residents of Denmark between 2000 and 2017.

The primary objective of the current study was to assess whether a higher risk of infertility was associated with long-term exposure to pollution from particulate matter with a diameter of less than 2.5 micrometers (µm) (PM 2.5 ) and road traffic noise.

The Danish National Patient Register was used to obtain data on individual-level noise, air pollution, and socioeconomic variables. Data from the Building and Housing Register were analyzed to obtain participant residential addresses for estimating road traffic noise and air pollution.

Study findings

In the study cohort, 16,172 men and 22,671 women were diagnosed with infertility during an average follow-up period of 4.3 and 4.2 years, respectively. Distributions of exposure levels to noise and air pollution were similar across men and women.

Exposure to PM 2.5 was associated with a higher risk of infertility in men across all age groups. In men between 30 and 36.9 years of age, no association was observed between noise and infertility; however, the consideration of PM 2.5 into this relationship led to a hazard ratio of less than one. In men between 37 and 45 years of age, infertility risk was slightly higher with noise exposure, irrespective of PM 2.5 adjustment.

Women between 35 and 45 years of age were at a greater risk of infertility when they were exposed to noise, whereas no association was observed in women between 30 and 34.9 years of age. Across both age groups, infertility risk was not associated with exposure to PM 2.5 . Adjusting for other covariates did not significantly alter these relationships.

Among women between 35 and 45 years of age, noise was associated with a higher risk of anovulation, tubal factor, and unknown cause. Across both age groups, unknown infertility correlated with PM 2.5 exposure.

Among men of both age groups, higher PM 2.5 exposure was associated with an increased risk of oligospermia, azoospermia, and unknown infertility. In men between 37 and 45 years of age, noise was associated with an increased risk of unknown infertility. Comparatively, noise was weakly associated with a reduced risk of azoospermia and unknown infertility in men between 30 and 36.8 years of age.

The increased risk of PM 2.5 -related infertility in men and noise-related infertility in women were consistent, regardless of whether the individual resided in urban, suburban, and rural areas, as well as those of high, medium, and low socioeconomic status. For noise, stronger associations with infertility were observed among those without a silent facade at home.

Conclusions

High exposure to air pollution was associated with a greater risk of infertility in men, whereas a higher infertility risk was observed among women 35 years of age and older exposed to road traffic noise. The association between traffic noise and infertility in older men was weak.

Future studies are needed to validate the current study findings. Nevertheless, these observations suggest the need for air pollution and noise mitigation policies to improve birth rates in western countries.

Participants 526 056 men and 377 850 women aged 30-45 years, with fewer than two children, cohabiting or married, and residing in Denmark between 2000 and 2017.

Main outcome measure Incident infertility in men and women during follow-up in the Danish National Patient Register.

Results Infertility was diagnosed in 16 172 men and 22 672 women during a mean follow-up of 4.3 years and 4.2 years, respectively. Mean exposure to PM 2.5 over five years was strongly associated with risk of infertility in men, with hazard ratios of 1.24 (95% confidence interval 1.18 to 1.30) among men aged 30-36.9 years and 1.24 (1.15 to 1.33) among men aged 37-45 years for each interquartile (2.9 µg/m 3 ) higher PM 2.5 after adjustment for sociodemographic variables and road traffic noise. PM 2.5 was not associated with infertility in women. Road traffic noise (Lden, most exposed facade of residence) was associated with a higher risk of infertility among women aged 35-45 years, with a hazard ratio of 1.14 (1.10 to 1.18) for each interquartile (10.2 dB) higher five year mean exposure. Noise was not associated with infertility among younger women (30-34.9 years). In men, road traffic noise was associated with higher risk of infertility in the 37-45 age group (1.06, 1.02 to 1.11), but not among those aged 30-36.9 years (0.93, 0.91 to 0.96).

Conclusions PM 2.5 was associated with a higher risk of an infertility diagnosis in men, whereas road traffic noise was associated with a higher risk of an infertility diagnosis in women older than 35 years, and potentially in men older than 37 years. If these results are confirmed in future studies, higher fertility could be added to the list of health benefits from regulating noise and air pollution.

Introduction

Infertility is a major global health problem affecting one in seven couples trying to conceive. 1 Infertility affects all geographical areas of the world, with some of the highest rates observed in south and central Asia, sub-Saharan Africa, the Middle East, north Africa, and central and eastern Europe. 2 Infertility is defined as lack of conception after one year of regular, unprotected sexual intercourse. 3 The use of various assisted reproductive technologies has increased noticeably since the 1980s, and more than 10 million children have been conceived using such technologies worldwide. 4 Infertility in both men and women is associated with various long term adverse health effects, including shorter life expectancy and increased risk of various psychiatric disorders and somatic diseases. 5 6 Furthermore, infertility is often a harsh experience, with a high level of physical and psychological strain, including high stress levels, anxiety, and symptoms of depression. 7 8

Many of the established risk factors for infertility are similar for men and women and include advanced age (especially for women, where fertility drops rapidly after the late 30s), tobacco and alcohol use, sexually transmitted infections, various chronic conditions and diseases, obesity, and severe underweight. 9 In addition, exposure to environmental factors, such as air pollution, pesticides, and ionising radiation, are suspected risk factors for infertility. 10 Ambient air pollution is a major environmental pollutant causing cardiometabolic and respiratory morbidity and mortality. 11 12 Furthermore, during the past decade, epidemiological studies have found particulate air pollution to be negatively associated with sperm quality, specifically lower sperm motility and count and changes in sperm morphology. 13 14 15 A growing number of studies have indicated that air pollution is also associated with a reduced success rate after fertility treatment in women, 16 17 18 19 20 although results are inconsistent. 21 22 23 In contrast, only a few studies have studied the effects of air pollution on infertility in women, with inconsistent results. 24 25 26 27 Also, these studies mainly investigated effects on fecundability, thus not capturing infertility in women directly, as fecundability can be influenced by infertility in both men and women.

Road traffic noise is another prevalent environmental pollutant that has been linked with various chronic diseases. 28 29 30 Health effects of noise are suggested to be mediated through the triggering of a stress response, with activation of the autonomic nervous system and the hypothalamic-pituitary-adrenal axis, 31 as well as through sleep disturbance. 32 Both stress and sleep disturbance have been suggested to be associated with impaired reproductive function, including reduced sperm count and quality, menstrual irregularity, and impaired oocyte competence. 33 34 35 A main suggested biological pathway is activation of the hypothalamic-pituitary-adrenal axis, with release of stress hormones and inhibition of the hypothalamic-pituitary-gonadal axis, resulting in decreased levels of male and female sex hormones. 33 34 35 Only one study has investigated the effects of noise on fertility, specifically self-reported time to pregnancy in a cohort of ≈65 000 pregnant women, and the results indicated that road traffic noise was associated with an increased time to pregnancy. 36

We investigated if long term exposure to road traffic noise and pollution from particulate matter air with a diameter <2.5 µm (PM 2.5 ) in the Danish population was associated with a higher risk of infertility in men and women, using individual level, time varying information on noise, air pollution, and socioeconomic variables and follow-up for infertility in the Danish National Patient Register.

Study population

Our study was based on all people residing in Denmark. Since 1968, all Danish inhabitants have been assigned a unique identification number, enabling linkage between administrative and health registers. 37 We used the Civil Registration System with exact address data for people in Denmark, including moving and migration dates, to find the address history from 1995 onwards. 37 We generated a study population for women and a study population for men and both study populations included people aged 30-45 years who were cohabiting or married, had fewer than two children, and lived in Denmark between 1 January 2000 and 31 December 2017 (n=377 850 women; 526 056 men). These inclusion criteria were implemented to obtain study populations with a high proportion of individuals who were actively trying to become pregnant, and thus under risk of receiving an infertility diagnosis.

Estimation of road traffic noise

We used the Building and Housing Register to obtain geocode and floor (for multistorey buildings) for all addresses in Denmark, and estimated road traffic noise at these addresses for 1995, 2000, 2005, 2010, and 2015 based on the validated Nordic prediction method. 38 39 Main traffic variables for the model were road type (motorway, express road, road wider than 6 m, road 3-6 m wide, and other road) and data on distributions of light and heavy vehicles, travel speed, and annual average daily traffic for all Danish roads. 40 We accounted for screening effects from all Danish buildings, noise barriers and terrain, reflections, and ground absorption. Noise was calculated as the equivalent A weighted sound pressure level for the day, evening, and night, and expressed as Lden. We estimated noise at the most and the least exposed facades of the residence at each address. Values <35 dB were set to 35 dB because noise below this level is unlikely to be discernible from background noise. We estimated yearly means for all addresses at all years between 1995 and 2017 using linear interpolation.

Estimation of air pollution

We assessed PM 2.5 at all addresses (ground level) using a validated modelling system comprising the Danish eulerian hemispheric model, the urban background model, and the operational street pollution model. 41 42 43 This system calculated PM 2.5 at all Danish addresses as the sum of air pollution at three different spatial scales: the regional background, estimated by a long range chemistry-transport model at 5.6-150 km 2 resolution (the Danish eulerian hemispheric model) 41 ; local background, estimated in the urban background model covering Denmark in 1 km 2 resolutions 42 ; and local street, calculated in the operational street pollution model, which takes into account traffic, street configurations, and emission factors. 43 All models include weather conditions calculated using the weather research and forecasting model. 44 The model system estimated hourly address specific concentrations of PM 2.5 during 2000, 2010, and 2015, which were summarised to yearly means for each of the three years. We subsequently calculated yearly means for each address for the period 1995-2017, based on yearly changes in urban background PM 2.5 estimated using the Danish eulerian hemispheric model and the urban background model.

Covariates were selected based on availability in the Danish registers and plausibility to act as potential confounders (see supplementary figure S1). We collected yearly individual level information from 2000 to 2017 using national registers on individual income (sex and year standardised fifths), highest attained education (mandatory, secondary or vocational, or medium or long), occupational status (manual worker, professional, or unemployed or retired), number of children (0 or 1), and country of birth (Denmark or other). We obtained yearly information on five neighbourhood level variables: Proportion of inhabitants in each parish (on average 16.2 km 2 and 1032 residents) with only mandatory education, low income, manual labour, and a criminal record, and as sole providers. We estimated population density in each parish (0-100, 100-5000, and >5000 individuals/km 3 ) and received information on house type for all addresses (single family house, semidetached house, apartment, or other).

Ascertainment of infertility

To assess infertility, we used personal identification numbers to link the two study populations of men and women with the Danish National Patient Register (valid since 1977), using ICD-8 and ICD-10 (international classification of diseases, eighth and 10th revisions, respectively) codes. 45 Infertility in women was registered as ICD-8 code 628 and ICD-10 code N97 (excluding N974: infertility in women due to male factors), and infertility in men was registered as ICD-8 code 606 (excluding 606.59, 606.80-89) and ICD-10 code N46 (excluding N469E: infertility in men after sterilisation). We only included the first registered infertility diagnosis. All individuals with a diagnosis of infertility before baseline were excluded. We also excluded women with tubal ligation, bilateral oophorectomy, or hysterectomy before baseline and men who were sterilised before baseline (see supplementary table S1 for operation codes). Furthermore, people undergoing any of these procedures during follow-up were censored at the date of the operation.

For analyses of infertility subtypes, we investigated anovulation (N970), tubal factor (N971), unspecified (N979), and a joint group of other causes of infertility in women (N972, N973, and N978) as subtypes of infertility in women, whereas azoospermia (N469B), oligospermia (N469C), and unspecified (N469) were included as subtypes of infertility in men. Low numbers for other infertility subtypes in men and women precluded meaningful analyses.

Statistical analyses

We analysed data using Cox proportional hazards models, with age as the underlying timescale, to calculate hazard ratios and 95% confidence intervals (CIs) for infertility in men and women (overall and for subtypes of infertility) for each interquartile range as well as for each 10 dB and 5 µg/m 3 increase in road traffic noise and PM 2.5 , respectively. Exposure to both pollutants was modelled as time weighted five year running means, taking exposure at all addresses in the period into account (including moving), and entered as time varying variables into the Cox model, thus for each individual with infertility comparing with the five year mean exposure for all people without infertility at the same age as the individual with infertility at the time of diagnosis. Start of follow-up was defined as 30 years of age, 1 January 2000, or date of marriage or cohabiting, whichever came last, and the study populations were followed until date of infertility diagnosis, death, emigration, unknown address, bilateral oophorectomy (women only), tubal ligation (women only), hysterectomy (women only), sterilisation (men only), 45 years of age, divorce or end of cohabitation, birth of second child, or 31 December 2017, whichever came first.

We analysed data using three adjusted models. Model 1 included adjustment for calendar year (two year categories). In model 2, we further adjusted for highest attained education, individual level income, country of origin, occupation, and area level proportion of inhabitants with low income, only mandatory education, manual labour, and a criminal record, and as sole provider. In model 3, we additionally applied mutual adjustment for PM 2.5 and noise. All individual and area level covariates except country of origin were entered into the Cox models as yearly time varying variables (area level variables also changed with change of address).

We evaluated the assumption of proportional hazards for the three exposures by a correlation test between the scaled Schoenfeld residuals and the rank order of event time. We observed a strong deviation from the assumption for noise (noise at both the most and the least exposed facade) in the men and women study populations. To investigate this further, we calculated associations between the two noise exposures and infertility in men and women in the following age groups: 30-30.9, 31-31.9, 32-32.9, 33-33.9, 34-34.9, 35-35.9, 36-36.9, 37-37.9, 38-38.9, 39-39.9, 40-41.9, and 42-45 years (see supplementary figure S2 and tables S2 and S3). We observed that the hazard ratios differed across age groups, indicating a shift in hazard ratio levels around age 35 years for women and 37 years for men. Subsequent analyses were therefore conducted in the following age groups: 30-34.9 and 35-45 years for women and 30-36.9 and 37-45 years for men.

To investigate the shape of the exposure-response associations, we used natural cubic splines with three degrees of freedom. We furthermore analysed associations (model 3) in categories of noise at the most exposed facade (≤50, 50.01-55, 55.01-60, 60.01-65, and >65 dB) and PM 2.5 (≤12, 12.01-14, 14.01-16, and >16 µg/m 3 ).

For men aged 37-45 years and women aged 35-45 years we analysed associations separately among people: living at low (<100 people/km 2 ), medium (101-5000 people/km 2 ), or high (≥5000 people/km 2 ) population density; with a low, medium, or high level of education; with a personal income in the first, second, third, and fourth income group; and with 0 or 1 child, by including an interaction term in the model. Also, in analyses of noise at the most exposed facade, we investigated associations among people who had access to a silent facade with substantially lower noise levels than at the most exposed facade compared with people without a more silent facade (defined as a difference between noise at the most and least exposed facades above and below 10.8 dB, corresponding to the median). In sensitivity analyses, we further adjusted for population density and type of residence.

All statistical analyses were performed using SAS 9.4 (SAS Institute, Cary, NC), except tests for proportional hazards and the splines, which were done in R version 4.3.2.

Patient and public involvement

No patients were directly involved in defining the research question, in the study design, or in the analyses and reporting. A main reason was that the present study was conducted without any external funding, thus with limited resources to engage in patient and public involvement. However, discussions with citizens concerned about the effects of the environmental pollutants studied and with patients experiencing infertility and worrying about the causes helped to motivate initiation of the study.

Of 1 133 142 men and 1 090 344 women aged between 30 and 45 years (2000-17) identified, we excluded 12 654 men with an infertility diagnosis or sterilisation before baseline, and 85 700 women with an infertility diagnosis, bilateral oophorectomy, tubal ligation, or hysterectomy before baseline. We further excluded 310 940 men and 458 002 women who had two or more children (or with missing information) at time of enrolment, and 222 796 men and 123 188 women who did not live with a partner at any time during follow-up or were in a same sex registered partnership (or with missing information). We also excluded 30 395 men and 21 872 women with an incomplete address history five years before baseline, and 30 301 men and 23 732 women lacking information on any covariates. This resulted in study populations of 526 056 men and 377 850 women of whom 16 172 men and 22 671 women had an infertility diagnosis during a mean follow-up of 4.3 years and 4.2 years, respectively.

Table 1 shows the baseline sociodemographic and exposure characteristics of the two study populations. Distributions of exposure and median levels of noise and PM 2.5 as well as correlations between exposures were similar among men and women ( table 1 , also see supplementary figure S3). Noise at the most and least exposed facades were moderately correlated, with Spearman correlation coefficient (Rs) for women of 0.38, whereas correlations between noise and PM 2.5 were low, with Rs between 0.05 and 0.16 (see supplementary table S4). Median five year mean PM 2.5 levels decreased in the study population during the follow-up period, from 17.3 µg/m 3 in 2000 to 12.1 µg/m 3 in 2017, whereas five year mean noise levels increased slightly from 57.7 dB in 2000 to 59.1 dB in 2017 (see supplementary table S5). Owing to highly non-linear associations between noise at the least exposed facade and infertility in both men and women, we did not conduct further analyses with this noise measure as a continuous variable (see supplementary figure S4).

Among men, we observed that exposure to PM 2.5 was associated with a higher risk of infertility, with similar sized hazard ratios in the two investigated age groups (30-36.9 and 37-45 years) in the fully adjusted model 3 ( table 2 ). The categorical analyses ( table 3 ) and splines ( fig 1 ) showed that the associations followed linear exposure-response associations throughout the exposure range. For noise, we observed no association with infertility in men in the youngest age group (30-36.9 years) before adjustment for PM 2.5 (model 2), whereas after adjustment, noise was associated with a hazard ratio of <1 (model 3, table 2 ). In the oldest age group (37-45 years), noise was associated with a slightly higher risk of infertility in men both before and after adjustment for PM 2.5 . For both exposures, further adjustment for population density and type of residence resulted in only small changes in hazard ratios (see supplementary table S6). After further adjustment for children (0 or 1) the hazard ratio for noise was reduced in the 37-45 age group, from 1.06 (95% CI 1.02 to 1.11) to 1.02 (0.98 to 1.07), whereas the association with PM 2.5 remained unchanged (see supplementary table S6).

Among women, noise was associated with a higher risk of infertility in the 35-45 age group, whereas no association was observed in the 30-34.9 age group ( table 2 ). The association with noise in the oldest age group followed a close to linear exposure-response association, although at high exposures (>65 dB) the association levelled off ( table 3 , fig 1 ). Exposure to PM 2.5 was not associated with higher risk of infertility in women in any of the investigated age groups. For both exposures, further adjustment for population density, type of residence, and number of children resulted in only slight changes in hazard ratios (see supplementary table S6).

When investigating the effects of the two exposures on infertility subtypes in women, we found that noise was associated with a higher risk of all three subtypes investigated (anovulation, tubal factor, and unknown cause) in the 35-45 age group but not in the 30-34.9 age group, whereas PM 2.5 was associated with higher risk of unknown infertility in both age groups ( table 4 ). For subtypes of infertility in men, we observed positive associations between PM 2.5 and the three subtypes investigated (oligospermia, azoospermia, and unknown infertility) in both age groups. Noise seemed to be associated with a reduced risk of azoospermia (although based on only 273 people) and unknown infertility in men in the 30-36.9 age group and a higher risk of unknown infertility in men in the 37-45 age group.

Associations between an interquartile range higher five year mean road traffic noise at the most exposed facade and PM 2.5 in relation to subtypes of infertility in men and women

We found similar hazard ratios between the two exposures and infertility in women and between PM 2.5 and infertility in men across areas of low, median, and high population density; low, median, and high individual level education; and fourths of personal income, whereas for noise and infertility in men, associations were only observed among men living in low and median population densities, with low or medium educational level, or with income above the lowest fourth, or a combination of these ( fig 2 , see supplementary table S7). When comparing hazard ratios across people with no children or one child, we observed similar hazard ratios for both exposures in relation to infertility in men, whereas for infertility in women, noise was only associated with higher risk for primary infertility (for secondary infertility we observed a hazard ratio <1) and PM 2.5 was only associated with a higher risk of secondary infertility ( fig 2 , see supplementary table S7).

Associations between an interquartile range higher five year mean road traffic noise and PM 2.5 and risk of infertility among men aged 37-45 years and women aged 35-45 years, according to population density, education, personal income, number of children, and access to a silent façade at home. CI=confidence interval; dB=decibel; PM 2.5 =fine particulate matter with a diameter <2.5 μm

When investigating the association between noise at the most exposed facade and infertility among people with a large versus a small difference between noise level at the most and least exposed facades, we observed stronger associations only when a small difference in noise existed between the two facades, corresponding to having “no silent facade” ( fig 2 , see supplementary table S7).

Based on a large nationwide, prospective cohort, designed to include a high proportion of people actively trying to achieve pregnancy, we found that mean five year exposure to noise was associated with a higher risk of infertility among women aged between 35 and 45 years, whereas no associations were observed between PM 2.5 and infertility in women. The association between noise and infertility in women seemed confined to those without children (primary infertility). For men, we observed that five year exposure to PM 2.5 was associated with a higher risk of infertility across the investigated age range (30-45 years), and noise seemed weakly associated with infertility among men aged 37-45 years. The higher risk of noise related infertility in women and PM 2.5 related infertility in men was consistent across people living in rural, suburban, and urban areas as well as across people with low, medium, and high socioeconomic status. For noise, we observed stronger associations with infertility among people without a silent facade at home.

Strengths and limitations of this study

Strengths of this study include the nationwide design, with low risk of selection bias, together with a high number of people with incident infertility identified from high quality registers during a follow-up period of 18 years. To optimise the likelihood of obtaining valid and unbiased results, we restricted the study population to include a high proportion of people who were at risk of an infertility diagnosis—that is, those who were actively trying to become pregnant. Accordingly, our study population included men and women aged 30-45 years who were married or cohabiting. Furthermore, all study participants were censored at the time they had their second child. This censoring criterion was applied because Danish women on average gave birth to 1.8 children during the study period and therefore it is likely that after the birth of a second child, many couples no longer try for pregnancy. Although applying these restriction criteria increased the probability that a large proportion of our study population were trying to become pregnant, it was inevitable that our cohort also included couples who were not—for example, couples prioritising their career before children. This is a limitation of the study design.

People with infertility were identified using the high quality Danish National Patient Register, which has high validity and completeness of diagnoses in Denmark. 46 Thus, only infertile couples actively seeking infertility counselling were identified as infertile participants in the study. In Denmark, however, all inhabitants can seek infertility counselling and fertility treatment free of charge, and the procedures are standardised across Denmark, starting with a visit to the general practitioner who, if infertility is suspected, refers individuals to a fertility clinic. As Denmark is a small country, the distance between home and a fertility clinic is not expected to be an obstacle to seeking fertility treatment, and we did not expect major differences in the likelihood of obtaining an infertility diagnosis according to geographical location alone.

Another important strength was that we had access to an exact history of residential address for all participants from five years before baseline until end of follow-up, linked with exposure to both road traffic noise and PM 2.5 estimated used validated exposure models and high quality input data. 43 47 As these two exposures are correlated and found to be associated with many of the same diseases, mutual adjustment was crucial.

As the present study was based entirely on register data, we did not have information on lifestyle factors, such as alcohol use, smoking, and body mass index, which is a limitation. We did, however, have access to detailed time varying register based information on individual and neighbourhood level sociodemographic variables, enabling us to adjust for key socioeconomic covariates, thereby indirectly adjusting for lifestyle. That our adjustment strategy may sufficiently capture lifestyle confounding is supported by results from our previous studies on noise and air pollution and risk of cardiovascular disease, diabetes, and mortality, which were based on large Danish questionnaire based cohorts with detailed information on lifestyle. 48 49 50 These studies showed that after adjusting for the socioeconomic variables included in the present study, further adjustment for lifestyle had only a minimal effect on the risk estimates. Another limitation is lack of information on exposure to noise and PM 2.5 at work and at leisure time activities away from home. This may affect the size and statistical precision of risk estimates owing to a mixture of classic and Berkson error.

Comparison with other studies

In support of our results on PM 2.5 and infertility in men, particulate air pollution (PM 2.5 and PM 10 ) has in recent studies been found to be negatively associated with factors defining sperm quality, including sperm motility and count as well as changes in sperm morphology. 13 14 15 Our study therefore adds to these findings, showing that the effects of air pollution on sperm quality will potentially result in a higher risk of requiring assistance from a fertility clinic to achieve pregnancy. Interestingly, we found that the association between air pollution and infertility in men followed a linear exposure-response association, starting from around ≥8.5 µg/m 3 in both investigated age groups, indicating that even at the relatively low levels of PM 2.5 found in Denmark, particulate air pollution can reduce fertility in men.

For women, most previous studies have focused on investigating effects of air pollution on success of fertility treatment among couples referred to fertility clinics. 16 17 18 19 20 21 22 23 Although most studies found particulate matter air pollution to be associated with, for example, a reduced likelihood of clinical pregnancy, live birth after fertility treatment, and odds of receiving fertility treatment, 16 17 18 19 20 others found no association. 21 22 23 Also, the few studies investigating the effects of short term or long term, or both, exposure to air pollution on fecundability (assessed as time to pregnancy) have provided inconsistent results. 25 26 27 However, fecundability can be influenced by infertility in both men and women, and therefore results are difficult to interpret in the context of infertility in women, as a positive association can potentially be driven by effects of air pollution on semen quality. The results from these previous studies can therefore not be directly compared with the present study, where we have direct and differentiated measures of infertility in men and women. However, in a study based on 36 000 women from the Nurses’ Health Study II with self-reported follow-up for infertility (defined as attempting conception for ≥12 months), the authors were able to distinguish between infertility in men and women in 27% of women with fertility problems. 24 In both main analyses (couple based infertility) and analyses restricted to infertility in women, the authors reported that long term exposure to PM 2.5 (four year mean) was not associated with higher risk of infertility, which agrees with the results of the present study.

A potential explanation as to why we found PM 2.5 exposure associated with infertility in men and not women is that while female follicle development begins in utero, new sperm cells are produced continuously in the testis (after puberty), with an overall lifespan of three months. Therefore, particulate air pollution may act directly on the sperm cells during the vulnerable spermatogenesis phase—for example, through direct toxic effects of particles translocated from the lungs into the blood, oxidative stress, inflammatory processes, and genotoxicity. 51 52 In contrast, the potential biological mechanisms underlying an association between air pollution and infertility in women are less established but have been hypothesised to involve some of the same pathogenetic mechanisms as described for infertility in men as well as endocrine disrupting properties caused by air pollutants mimicking the effect of androgens and oestrogens. 53

The only previous study on traffic noise and a fertility related outcome indicated that among 65 000 pregnant women, road traffic noise was associated with a higher risk of trying for six months or more to achieve pregnancy (self-reported) compared with getting pregnant within six months. 36 This indicates that noise may impact fecundity, which supports the findings of the present study—although the two studies are not directly comparable, as the previous study focused on self-reported time to pregnancy among pregnant women, whereas the present study investigated risk of receiving a diagnosis of infertility. A potential explanation as to why we only observed an association with noise among women older than 35 years is that many who are trying to become pregnant in this age group are likely to be in a more stressful state than women in a younger age group if pregnancy is not achieved immediately, as it is well known that fertility drops steeply in women in their late 30s. 54 Therefore, women in this age group may be more susceptible to noise induced stress and sleep disturbance, 31 32 as they are potentially already in a state of distress. In support, we only observed a positive association with noise among women with primary infertility, who are expected to be in a more stressful state than women who already have one child (secondary infertility). It is established that infertility is associated with psychological symptoms, such as depression and distress, especially among women. 33 55 It is still, however, unclear whether stress is a risk factor for infertility. 33 Our finding of an association between noise and infertility only among women older than 35 years may also be partly explained by different underlying causes of infertility across age groups. For example, somatic disorders known to be important causes of infertility in women, such as endometriosis and polycystic ovary syndrome, are often diagnosed at a relatively early age and people with these disorders are thus more likely to contact fertility clinics for counselling at an earlier age. As we hypothesised that noise would have only a minor or no impact on the risk of infertility among individuals with a definite somatic cause of infertility, this may at least partly explain why we observed no association between noise and infertility in women in the 30-35 age group.

Among men, we observed that noise was associated with a lower risk of infertility in the 30-36.9 age group and a higher risk in the 37-45 age group. The biologically implausible lowering of risk in the youngest age group was, however, driven by adjustment for PM 2.5 , suggesting that this was an artefact. In the 37-45 age group, the association was robust to adjustment for PM 2.5 as well as to adjustment for population density, suggesting that noise may be a risk factor for infertility in men. After adjustment for number of children, however, the association was no longer present. More studies are needed to establish whether noise is a risk factor for infertility in men—for example, studies on noise and semen quality.

To investigate the robustness of our results, we examined whether our main findings were consistent across urban, suburban, and rural areas. In Denmark, couples who are considering starting a family are likely to move from apartments in larger cities to single family houses in suburban or rural areas, which in most instances will result in reduction of exposure to air pollution and noise. Although we had detailed information on changes of address (and exposure) for all participants, this could have potentially biased our results. However, the observed associations between PM 2.5 and infertility in men and noise and infertility in women were present regardless of the degree of urbanisation, suggesting that the high mobility of our population did not affect the results. In Denmark, people of high socioeconomic status are more likely to live in urban areas than in more rural areas, and although infertility treatment is free of charge in Denmark, Danish couples with high education and high income are more likely to seek infertility treatment than couples with low education and low income. 56 One could also speculate that people in urban areas might have different healthcare seeking behaviour than people in more rural areas. However, we observed comparable risk estimates for noise and air pollution among people with low, medium, and high educational level as well as among fourths of personal income, indicating that the results were not driven by socioeconomic differences in exposure levels or health seeking behaviour, or both.

Noise at the least exposed facade of a home is hypothesised to be a proxy for exposure to noise during nighttime sleep, as many people prefer their bedroom away from a busy street. 57 We observed that associations between this noise estimate and infertility across both men and women and age groups followed a linear association from 35 dB to around 45 dB, after which the association either levelled off or became negative. This makes it difficult to draw conclusions about the effects of noise at the least exposed facade on infertility. Therefore, to further explore whether noise at the least exposed facade had an impact on infertility risk, we investigated the effects of noise at the most exposed facade among people who had access to a “silent side,” which we defined as having a facade with substantially lower levels of road traffic noise than at the most exposed facade, compared to people with no silent side. Interestingly, we found that hazard ratios for noise at the most exposed facade and infertility among women with a silent side were markedly lower than among people without a silent side. This suggests that having access to a more silent facade may protect against the stressful effects of noise.

Conclusions

Based on a nationwide cohort, designed to include a high proportion of people actively trying to achieve pregnancy, we found that PM 2.5 was associated with a higher risk of an infertility diagnosis among men and road traffic noise was associated with a higher risk of an infertility diagnosis among women older than 35 years, and possibly among men older than 37 years. As many western countries are facing declining birth rates and increasing maternal age at the birth of a first child, knowledge on environmental pollutants affecting fertility is crucial. If our results are confirmed in future studies, it suggests that political implementation of air pollution and noise mitigations may be important tools for improving birth rates in the western world.

What is already known on this topic

Particulate air pollution and transportation noise are the two largest environmental causes of disease and death

Particulate air pollution has been associated with reduced sperm quality and reduced success of fertility treatment, whereas results on fecundability are inconsistent

Although one study found road traffic noise to increase time to pregnancy, no studies have investigated the effects of transportation noise on incident infertility in men and women

What this study adds

Exposure to particulate air pollution was associated with an increased risk of an infertility diagnosis in men

Road traffic noise was associated with a higher risk of an infertility diagnosis among women older than 35 years, and potentially among men older than 37 years

If these findings are confirmed in future studies, they may prove important in guiding decision makers responsible for setting priorities and implementing mitigations strategies to protect the general population from these exposures
