Sound levels above 85 decibels can damage human hearing
Noise pollution is any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. Sound is measured in decibels, and sounds that reach 85 decibels or higher can harm a person's ears. This is because sound waves are vibrations of air molecules carried from a noise source to the ear, and the louder the sound, the bigger the sound wave.
The normal human ear can detect sounds ranging from 0 dB (hearing threshold) to approximately 140 dB, with sounds between 120 dB and 140 dB causing pain. Sounds at 85 dB can lead to hearing loss if one listens to them for more than eight hours at a time. For every 3-dB rise in noise levels over 85 dB, the safe listening time is cut in half. For example, if the sound increases to 88 dB, it is safe to listen to those sounds for only four hours. If the sound goes up to 91 dB, the safe listening time is reduced to two hours.
Sounds of 110-120 dB can cause hearing damage even with very short exposure times. In a nightclub where the music plays at an average volume of 100 dB, one is at risk of hearing damage after just 15 minutes without ear protection. Some common sources of such noise levels include power lawn mowers (90 dB), subway trains (90-115 dB), and loud rock concerts (110-120 dB).
Noise pollution can have a range of negative impacts on humans, including hearing loss, high blood pressure, heart disease, sleep disturbances, stress, and cognitive decline. It can also affect mental health, causing irritability, anxiety, and mental fatigue. Additionally, noise pollution can interfere with communication, sleep, recreation, and personal communication.

Noise pollution impacts the health and behaviour of wildlife
Noise pollution, defined as any unwanted or excessive sound, can have detrimental effects on human health, wildlife, and environmental quality. It is commonly generated in industrial facilities, workplaces, and through highway, railway, and airplane traffic.
Impact on Wildlife Behaviour
Noise pollution can interfere with an animal's ability to attract a mate, communicate, navigate, find food, or avoid predators. This interference can lead to a decline in reproduction and higher mortality rates. European robins, for instance, are more likely to sing at night in places with high levels of noise pollution during the day, indicating that they are adapting to quieter times to communicate more effectively.
Impact on Wildlife Health
Anthropogenic noise has been identified as a potential threat to the survival of many species. It can cause stress and other health issues in animals, such as increased heart rate in caterpillars and reduced chick count in bluebirds. Additionally, it can alter the feeding behaviour of certain species, as seen in the case of endangered blue whales.
Impact on Marine Life
Whales and dolphins are particularly vulnerable to noise pollution, as they rely on echolocation for various essential activities. Naval sonar devices, with sound levels up to 235 decibels, can interfere with their ability to echolocate, leading to mass strandings on beaches. The once tranquil marine environment has become loud and chaotic due to noise from ships, oil drills, and seismic tests.
Impact on Terrestrial Organisms
Terrestrial organisms are also affected by noise pollution. Studies have shown that chronic noise exposure can reduce the size of an area where predators can hear their prey by up to 70%. This reduction in auditory range can have significant implications for the survival and behaviour of both predators and prey.
Overall, noise pollution poses a serious threat to the health and behaviour of wildlife, with potential consequences for the persistence of many species.

It can cause high blood pressure, heart disease, and sleep disturbances
Noise pollution is considered any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. Sounds that reach 85 decibels or higher can harm a person's ears. Sources of such sounds include power lawn mowers, subway trains, and loud rock concerts.
Noise pollution has been linked to several health issues, including high blood pressure, heart disease, and sleep disturbances. Firstly, regarding high blood pressure, studies have found a correlation between environmental noise and elevated blood pressure. For example, research on aircraft noise found that while daytime noise did not significantly impact blood pressure, there was a notable increase in blood pressure with higher levels of nighttime noise. Similarly, a Swiss study showed that railway noise negatively impacted blood pressure, particularly during the night. These findings suggest that nocturnal noise may be more detrimental than daytime noise when it comes to blood pressure.
Noise pollution has also been associated with an increased risk of heart disease. Long-term exposure to traffic noise, for instance, has been linked to a higher likelihood of heart attacks, strokes, and other severe heart-related issues. A study that analyzed data from nearly 500 adults over five years found that every 5-decibel increase in average 24-hour noise levels was associated with a 34% rise in these heart-related problems. Additionally, higher noise levels were linked to heightened activity in the amygdala, the brain region responsible for processing stress, anxiety, and fear, which may explain the connection between noise and cardiovascular risk.
Lastly, noise pollution can cause sleep disturbances, particularly during the night. Nocturnal environmental noise has been shown to impair sleep quality both objectively and subjectively, leading to daytime sleepiness, tiredness, annoyance, mood changes, decreased well-being, and reduced cognitive performance. While the direct link between noise-induced sleep disturbances and negative health outcomes is still uncertain, there is a hypothesis that poor sleep may mediate the relationship between nocturnal noise pollution and increased cardiovascular risk.

Children are especially vulnerable to the effects of noise pollution
Noise pollution is defined as any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. It is measured in decibels, and sounds that reach 85 decibels or higher can harm a person's ears.
Children with Autism Spectrum Disorder (ASD) who experience hyperacusis, or an abnormal sensitivity to sound, may feel fear and anxiety and experience uncomfortable physical sensations in noisy environments. Pediatricians can discuss the safe use of personal listening devices (PLDs) with parents and families and recommend hearing evaluations for children with a history of excessive noise exposure or conditions such as tinnitus or hyperacusis.
Noisy classrooms and childcare settings can also affect how children learn. Background noise or loud conversations can make it difficult for children to read, remember, and perform well on tests. Planes flying overhead can make it hard for children to hear and understand their teachers, causing them to lose focus.
To protect children from the harmful effects of noise pollution, it is recommended to avoid loud environments and noises, such as concerts, sporting events, and fireworks displays, especially for young children. Hearing protection, such as protective earmuffs, can be used, although earplugs may pose a choking hazard for younger children. Reducing the volume on televisions, computers, radios, and PLDs is also advised.

Noise levels in the workplace are regulated by law
Noise pollution is defined as any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. Sound is measured in decibels, and sounds reaching 85 decibels or higher can harm a person's ears.
To ensure compliance with these regulations, employers can use sound level meters, noise dosimeters, octave band analyzers, or mobile apps to measure noise levels in the workplace. If noise levels exceed the permissible limit, employers are required to implement a Hearing Conservation Program, which includes providing free annual hearing exams, hearing protection, training, and evaluations of the adequacy of hearing protection.
Additionally, the National Institute for Occupational Safety and Health (NIOSH) has developed the NIOSH Sound Level Meter App, which is available for iOS devices. This app helps users measure sound levels, generate reports, and access information about noise exposure parameters to reduce occupational noise-induced hearing loss.
It is important to note that noise levels should be regularly monitored and re-measured whenever changes are made that could impact exposure levels. Employers should also involve workers in the noise monitoring process and provide them with information about their daily noise exposure to effectively prevent hearing loss.
