Sound or noise pollution refers to the propagation of noise or sound with potentially harmful effects on humans, animals, and the environment. It is considered any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. Sources of sound pollution include machines, transport, and propagation systems. It can cause hearing loss, stress, high blood pressure, heart disease, sleep disturbances, and even existential threats to vulnerable organisms. Sound pollution is particularly harmful to marine animals, such as whales and dolphins, that rely on echolocation for survival. It can also have negative effects on adults and children on the autistic spectrum, as well as causing behavioural issues in humans.

Sound pollution is defined as unwanted or disturbing sounds
Sound pollution, also known as noise pollution, refers to unwanted or disturbing sounds that have potentially harmful effects on humans, animals, and the environment. It is considered an invisible danger as it cannot be seen, tasted, or smelled, but it can cause significant harm to the health and well-being of those exposed.
Sound pollution is typically caused by machines, transport, and propagation systems, with sources such as loud music, traffic, rail, airplanes, lawn care, construction, electrical generators, wind turbines, and explosions. Poor urban planning can also contribute to sound pollution, such as the proximity of industrial and residential buildings.
The impact of sound pollution on human health is significant. Exposure to loud or persistent noise can lead to hearing loss, high blood pressure, heart disease, sleep disturbances, stress, anxiety, and mental fatigue. It can also interfere with communication, concentration, and cognitive abilities, particularly in children. According to the World Health Organization (WHO), noise above 65 decibels (dB) is considered sound pollution, and restful sleep is impossible with nighttime ambient noise levels above 30 dB.
Sound pollution also has detrimental effects on wildlife and marine life. Animals use sound for navigation, finding food, attracting mates, and avoiding predators. The increasing noise in oceans and on land from ships, oil drills, seismic tests, and human activities interferes with these essential tasks, impacting the survival and behaviour of many species. Marine mammals, such as whales and dolphins, that rely on echolocation for communication and navigation, are particularly vulnerable to sound pollution.
Addressing sound pollution is crucial for the well-being of humans and ecosystems. Implementing noise reduction strategies, improving urban planning, and raising awareness about the impacts of sound pollution can help mitigate its negative effects.

It can cause hearing loss, stress, high blood pressure, heart disease, and sleep disturbances
Sound or noise pollution refers to any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. Sources of sound pollution include transportation noise, such as traffic noise, subway trains, and aircraft noise, as well as sounds from rock concerts, construction sites, and everyday activities like lawn mowing.
Noise pollution can cause hearing loss, especially when sounds reach 85 decibels or higher. Sounds at this volume or higher are capable of causing noise-induced hearing loss (NIHL). Some examples of loud noises that can lead to hearing loss include power lawn mowers (90 decibels), subway trains (90 to 115 decibels), and loud rock concerts (110 to 120 decibels).
In addition to hearing loss, noise pollution can also cause stress and increase stress responses in the body. Research has shown that the more people are bothered by noise, the greater the health risks they face. Even those who sleep through noise pollution experience autonomic stress reactions. Long-term exposure to traffic noise has been linked to heightened activity in the amygdala, the brain region involved in processing stress, anxiety, and fear. This may explain why chronic noise exposure is associated with an increased risk of cardiovascular problems.
Noise pollution has also been linked to high blood pressure, especially with exposure to nighttime noise. Studies have found that road traffic noise exposure has a larger impact on individuals who sleep with open windows or whose bedrooms face the road. Repeated nocturnal autonomic arousals may prevent the natural decrease in blood pressure during sleep, which is important for resetting the cardiovascular system and maintaining long-term cardiovascular health.
Finally, noise pollution can contribute to sleep disturbances, particularly with nocturnal environmental noise. Poor sleep caused by noise pollution can lead to daytime sleepiness and tiredness, decreased well-being and cognitive performance, and mood changes. These short-term effects may be followed by long-term adverse cardiometabolic outcomes, as sleep duration and quality are considered risk factors influenced by the environment.

It affects wildlife, including marine life, and can interfere with breeding cycles and survival
Sound or noise pollution refers to the propagation of noise or sound with potentially harmful effects on humans and animals. It is caused by machines, transport, and propagation systems. It can also be caused by poor urban planning, such as the construction of side-by-side industrial and residential buildings. Some common sources of noise in residential areas include loud music, transportation, lawn care maintenance, construction, electrical generators, wind turbines, explosions, and people.
Noise pollution affects wildlife, including marine life, and can interfere with breeding cycles and survival. It can cause hearing loss, stress, and high blood pressure in animals, similar to humans. 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 to navigate, find food, attract mates, and avoid predators. Noise pollution makes it difficult for them to accomplish these tasks, which affects their ability to survive.
Marine life is also severely impacted by noise pollution. As most marine species are highly dependent on sound for their survival, this type of pollution is extremely damaging to marine wildlife. It interferes with the key life functions of these animals and, in some cases, even causes death. For example, loud shipping noises around Californian shipping lanes have caused whales to abandon their critical feeding grounds in these areas, depriving them of essential nutrients and threatening their survival.
Whales and dolphins are particularly vulnerable to noise pollution as they rely on echolocation to communicate, navigate, feed, and find mates. Excess noise interferes with their ability to effectively echolocate. Some of the loudest underwater noises come from naval sonar devices and seismic tests, which can damage the ears of marine animals and cause serious injury. As a result, whales have changed their migration routes to avoid anthropogenic noise and altered their calls.
Noise pollution in the ocean has increased dramatically in recent decades, and it is important to take action to improve the ocean soundscape and enable the recovery of marine life. This includes implementing policies to reduce propeller noise from ships and mitigate the sounds of sonar equipment, seismic air guns, pile driving, and construction.

It is caused by machines, transport, and systems like wind turbines, airplanes, and construction
Sound or noise pollution refers to the propagation of noise or sound with potentially harmful effects on humans and animals. It is considered any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. The main sources of outdoor noise worldwide are machines, transport, and propagation systems.
Machines
Machines and mechanical equipment are a significant source of noise pollution. Machinery noise can emanate from industrial and construction sites, with loud machinery such as power lawn mowers, electrical generators, and cooling fans contributing to high noise levels. Machinery noise can also come from vehicles, including aircraft and ships. For instance, aircraft noise is a significant contributor to sound pollution, with jet engines and propellers producing compression and rarefaction of air, resulting in pressure waves that propagate as sound. The Auxiliary Power Unit (APU), an on-board generator used to start aircraft engines, is a major source of cabin noise in civilian and military aircraft. Machinery noise can have adverse effects on human health, including hearing loss, stress, high blood pressure, and heart disease.
Transport
Transportation is another primary cause of sound pollution, encompassing road traffic, rail, airplanes, and ships. Aircraft noise, in particular, has been the subject of various studies, highlighting its detrimental impact on human health. A German study found that aircraft noise increased the risk of coronary heart disease, with average sound pressure levels as low as 40 decibels having significant health effects. Long-term exposure to transport noise has negative consequences for physical and mental health, leading to annoyance, sleep disturbances, stress, and cognitive impairment, particularly in children.
Wind Turbines
The quest for cleaner energy has led to the expansion of wind turbine farms. However, wind turbines can generate noise pollution, known as wind turbine noise (WTN), which can impact nearby wildlife. WTN can affect the vital survival, social, and rearing mechanisms of certain species, including birds and bats. While research on the effects of WTN is ongoing, current planning guidelines in some countries do not adequately address these adverse impacts.
Construction
Construction sites are notorious for generating high levels of noise pollution due to the use of loud machinery, vehicles, and physical work such as hammering, drilling, or digging. Construction noise can lead to various health issues, including hearing loss, cardiovascular effects, and social impacts such as sickness. Poor urban planning can exacerbate construction noise pollution, with side-by-side industrial and residential buildings affecting residential areas. To mitigate these impacts, measures such as rotating shifts, using temporary barriers, and implementing industrial noise control regulations are crucial.

Poor urban planning, such as side-by-side industrial and residential buildings, can also contribute to sound pollution
Noise pollution, or sound pollution, is the propagation of noise or sound with potential harmful effects on humans and animals. It can cause hearing loss, stress, high blood pressure, heart disease, sleep disturbances, and even existential threats to vulnerable organisms.
Poor urban planning, such as side-by-side industrial and residential buildings, can indeed contribute to sound pollution. This is because industrial facilities and residential buildings produce different levels and types of noise, and when they are located next to each other, it can result in noise pollution for the residents. For example, industrial facilities often use large machinery and equipment that produce loud noises, which can interfere with the peace and comfort of those living in nearby residential buildings.
Thoughtful urban planning and zoning codes are essential to mitigating noise conflicts. Zoning laws can help to separate residential areas from commercial and industrial areas, ensuring that noise-sensitive land uses are not located adjacent to noisy sources. Building codes can also play a crucial role in reducing sound pollution by requiring acoustical insulation in bars, clubs, and residential buildings. This helps to contain noise within certain spaces and prevents it from becoming a nuisance to others.
Additionally, urban planning can address noise pollution by considering the design and placement of roads, highways, and railways. Roadway noise, for instance, can be reduced by utilising noise barriers, controlling vehicle speeds, altering roadway surface textures, and limiting heavy vehicles. Similarly, careful planning of new airports and their flight paths can help minimise noise disturbances for nearby residents.
Furthermore, urban planning can promote the use of quieter equipment and machines, as well as encourage improvements in their design to reduce noise emissions. This can include initiatives such as "Buy Quiet" programs, which incentivise the purchase and manufacturing of quieter tools and machinery. By addressing these various aspects of urban planning, communities can effectively reduce sound pollution and create more peaceful and healthy living environments for their residents.
