Noise pollution is a significant threat to both human health and the environment. It is caused by unwanted or excessive sound that has harmful effects on human health, wildlife, and environmental quality. Sources of noise pollution include industrial facilities, transportation, construction, and fossil fuel extraction and processing. The impacts of noise pollution include hearing loss, high blood pressure, sleep disturbances, stress, and cardiovascular disease. It also affects wildlife, with research showing that loud noises can interfere with breeding cycles and navigation, and even hasten the extinction of some species. Addressing noise pollution involves implementing noise mitigation measures, such as installing low-noise asphalt on roads and creating green spaces in urban areas.

Threat to human health: hearing loss, tinnitus, high blood pressure, heart disease, and sleep disturbances
Noise pollution is an invisible danger that affects the health and well-being of humans and other organisms. It refers to any unwanted or disturbing sound. 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-induced hearing loss (NIHL) is the most common health problem caused by noise pollution. NIHL occurs when the sensitive structures in the inner ear are damaged by loud sounds. NIHL can be temporary or permanent, affecting one or both ears. It can occur at any age and can be caused by one-time exposure to loud sounds, such as explosions, or continuous exposure to loud sounds over an extended period. Recreational activities that can put one at risk for NIHL include target shooting, hunting, and attending loud concerts.
Noise pollution can also cause tinnitus, a ringing, buzzing, or roaring in the ears or head. Tinnitus may subside over time but can sometimes continue throughout a person's life.
Additionally, noise pollution has been linked to high blood pressure and heart disease. Acute noise exposure can cause increases in blood pressure, heart rate, and cardiac output. Long-term exposure to traffic noise has been associated with a greater risk of heart attacks, strokes, and other serious heart-related problems. Nocturnal noise has been shown to affect autonomic regulation, increasing heart rate and blood pressure.
Furthermore, noise pollution can cause sleep disturbances, particularly at night. Poor sleep caused by environmental noise can lead to endocrine and metabolic perturbations, with negative cardiometabolic, psychiatric, and social outcomes. It can also affect sleep architecture and subjective sleep quality, leading to daytime sleepiness and tiredness.

Threat to wildlife: interferes with breeding cycles, hastening the extinction of some species
Noise pollution is a significant threat to wildlife, with potentially devastating consequences for breeding cycles and species survival. It is considered any unwanted or excessive sound that exceeds 75 decibels, as per the World Health Organization (WHO). This noise pollution can have far-reaching impacts on the health and well-being of both humans and other organisms.
The effects of noise pollution on wildlife are extensive. It can interfere with crucial biological functions, such as feeding and breeding, and alter the behaviour and physiology of species. For many animals, sound plays a vital role in their daily lives. They use it to navigate, find food, attract mates, and avoid predators. Noise pollution creates a challenging acoustic environment that hinders these essential tasks, threatening their ability to survive.
One example of noise pollution's impact on breeding cycles is seen in birds. Studies have shown that noise and light pollution can cause birds to begin nesting earlier than usual. In open environments, such as grasslands and wetlands, birds may start nesting up to a month earlier, while in forested environments, this advancement is around 18 days. Additionally, noise pollution has been found to delay nesting for bird species with lower-frequency songs, as these songs are more challenging to hear through low-frequency human noise.
Marine life also faces significant threats from noise pollution. Whales and dolphins, for instance, rely on echolocation for communication, navigation, feeding, and finding mates. The excessive noise from ships, oil drills, and seismic tests interferes with their ability to echolocate effectively. Sonar sounds, in particular, can be extremely loud, reaching up to 235 decibels, and can cause mass strandings of whales and alter the feeding behaviour of endangered blue whales.
The impact of noise pollution on wildlife is not limited to immediate behavioural changes. Chronic noise exposure over an animal's lifespan can lead to changes in species interactions and community dynamics. It can also increase the risk of death by modifying the delicate balance between predators and prey. The full extent of these community-level impacts is not yet well understood, which presents challenges in implementing effective mitigation strategies.

Threat to marine life: naval sonar devices interfere with whales' ability to use echolocation
Noise pollution is any unwanted or excessive sound that can have detrimental effects on human health, wildlife, and environmental quality. It is considered a serious threat to marine life, especially those that rely on echolocation, such as certain types of whales and dolphins. Naval sonar devices, with noise levels reaching up to 235 decibels, are among the loudest and most detrimental sources of underwater noise. Sonar works by transmitting sound pulses into the ocean depths, which then bounce off objects and return echoes to determine their location. This interference can disrupt the natural echolocation abilities of whales and dolphins, which they use to communicate, navigate, feed, and find mates.
Whales and dolphins use echolocation by clicking loudly through special nasal structures and listening for the echoes that bounce back. This ability is crucial for hunting in the dark ocean depths where their vision is limited. Sonar signals have been detected in over half of the recorded whale dives, and their presence has been shown to impact the whales' behaviour. When exposed to sonar signals, whales dived longer and descended more slowly to initiate their dives.
Research has also shown that beaked and blue whales are sensitive to mid-frequency active sonar and tend to move rapidly away from its source. This disruption can lead to changes in feeding behaviour and has been linked to mass strandings of whales. A notable example occurred in 2008, where naval exercises using mid- and high-frequency side-scan sonar were deemed the "most probable cause" of a mass stranding of around 50 short-beaked common dolphins in Falmouth Bay, Cornwall, UK.
The use of sonar has also been associated with decompression sickness in whales. This disease forces nitrogen into gas bubbles in the tissues and is caused by rapid and prolonged surfacing. While whales were initially believed to be immune to this condition, sonar interference has been implicated in causing behavioural changes that can lead to decompression sickness.
The impact of naval sonar on whale populations has led to environmental groups urging the U.S. Navy to stop or reduce the use of sonar during military training. Additionally, initiatives such as Washington state's Quiet Sound program aim to mitigate the effects of noise pollution on whale populations. By alerting commercial mariners to the presence of nearby whales, vessels can adjust their speed or course to give whales more space and quiet to feed and support their population growth.

Threat to mental health: stress, anxiety, and mental fatigue
Noise pollution is a serious threat to mental health, causing stress, anxiety, and mental fatigue. It is an invisible danger that can have a significant impact on the well-being of humans and other organisms. Unwanted or excessive sound can lead to a range of mental health issues and can affect people of all ages, from children to adults.
Chronic exposure to noise pollution keeps the body's stress response system activated, leading to increased stress levels. The amygdala, an area of the brain responsible for emotional processing, sends distress signals to the hypothalamus, which then signals the adrenal glands to release adrenaline and stress hormones like cortisol into the bloodstream. This evolutionary response prepares us for life-threatening situations, but when continuously activated by chronic noise, it can wear down the body and lead to mental and physical health issues.
Noise pollution can trigger anxiety, especially in individuals who feel they have no control over their noisy environment. Research has shown that a 10-decibel increase in aircraft noise was associated with a 28% increase in anxiety medication use. Additionally, people living in areas with more road traffic noise were 25% more likely to exhibit depressive symptoms.
Noise can also cause mental fatigue, impairing cognitive functions such as concentration, memory, and attention span. Children are particularly vulnerable to the effects of noise pollution, as it can interfere with their learning and development, impacting their ability to distinguish similar words and making reading more challenging.
The impact of noise pollution on mental health is a growing area of research, and it is increasingly recognized as a prominent environmental determinant of public health. While more studies are needed to fully understand the detrimental effects of noise on mental health, it is clear that noise pollution poses a significant threat to the mental well-being of individuals, especially those living in noisy urban environments.

Threat to children: stress, memory impairment, and attention deficits
Noise pollution is an invisible danger that can have a significant impact on human health, particularly in children. Loud noises can cause stress, memory impairment, and attention deficits in children, affecting their overall well-being and cognitive development.
Children are more susceptible to the detrimental effects of noise pollution, and their developing brains are more vulnerable to auditory stimuli. Research has shown that noise pollution can lead to increased stress levels in children. High levels of noise, such as those experienced in busy cities or near industrial areas, can cause a "fight or flight" response in the body, resulting in increased stress hormones and negative impacts on overall health.
Memory impairment is another consequence of noise pollution for children. Studies have found that children exposed to high levels of noise pollution perform worse on memory tasks and have lower reading comprehension scores compared to children in quieter environments. The constant noise can make it difficult for children to focus and consolidate information, leading to impairments in their memory retention and retrieval abilities.
Noise pollution also affects children's attention spans and abilities to focus. The presence of background noise or loud, unexpected sounds can make it challenging for children to concentrate on a task, particularly those with attention disorders or language impairments. This can result in difficulties with speech perception and listening comprehension and academic performance.
The impact of noise pollution on children's cognitive development is a growing area of concern. While the exact mechanisms are still being studied, researchers have found links between noise exposure and an increased risk of neuropsychiatric disorders, including cognitive decline and neurodevelopmental disorders. Therefore, it is crucial to address noise pollution and implement measures to reduce noise levels, especially in areas where children live, learn, and play, to ensure their health and well-being.
