What You'll Learn
Impact on human health: hearing loss, high blood pressure, stress, etc
Noise pollution, or sound pollution, is the propagation of noise or sound with potentially harmful effects on humans and animals. It is commonly generated inside many industrial facilities and some other workplaces, but it also comes from road, rail, and air traffic, as well as construction activities.
The impact of noise pollution on human health is significant. It can cause hearing loss, as loud or prolonged exposure to noise can damage the eardrum and the sensitive hair cells of the inner ear. This can result in temporary or permanent hearing loss, known as noise-induced hearing loss. Hearing loss typically does not occur at SPLs below 80 dBA, but exposure to sound levels above 85 dBA for eight hours can lead to some extent of permanent hearing loss. Noise pollution is also associated with tinnitus, a ringing or buzzing in the ears, which can be caused by exposure to loud noises.
In addition to hearing-related issues, noise pollution can lead to an array of other health problems. It can cause or exacerbate cardiovascular issues, including high blood pressure and an increased pulse rate. Research in Pakistan found that exposure to sound levels above 81 dB increased the chances of prehypertension and hypertension in the local population. Chronic noise exposure is estimated to contribute to 48,000 new cases of heart disease in Europe each year. Noise pollution can also cause irritability, anxiety, mental fatigue, and stress. It can interfere with sleep, affecting the depth and quality of rest and altering the amount of rapid eye movement sleep. This, in turn, can impact an individual's mood and ability to concentrate.
Children are particularly vulnerable to the negative health effects of noise pollution. They may suffer from stress and other issues, such as impairments in memory and attention span. Noise pollution can negatively interfere with a child's learning and behaviour, and the effects may be permanent. Additionally, individuals with Autism Spectrum Disorder (ASD) can experience hyperacusis, an abnormal sensitivity to sound, leading to unpleasant emotions and uncomfortable physical sensations in noisy environments.
Noise pollution has far-reaching consequences for human health, affecting both physical and mental well-being. It is important to address and mitigate noise pollution to safeguard the health and quality of life of individuals, especially children and those with ASD, who are more susceptible to its detrimental effects.

Impact on wildlife: communication, mating, navigation, etc
Noise pollution has a significant impact on wildlife communication, mating, and navigation, threatening the persistence of many species.
Impact on Wildlife Communication
Noise pollution can interfere with wildlife communication in several ways. Animals use various sounds, such as calls, songs, and echolocation, to communicate with each other. These sounds are essential for attracting mates, warning of danger, and maintaining social bonds within their species. However, noise pollution can mask or distort these animal signals, making it difficult for them to be heard or interpreted accurately. This disruption can lead to confusion, decreased social cohesion, and even isolation within animal communities.
For example, bird songs are crucial for territorial defence and mate attraction. Yet, in noisy environments, birds may need to adjust their songs to be heard, sometimes resulting in less effective communication or increased energy expenditure. Similarly, marine mammals like whales and dolphins rely on echolocation for navigation and finding prey, but underwater noise pollution from ships and offshore construction can interfere with their acoustic senses, impacting their ability to survive.
Impact on Mating and Reproduction
Noise pollution can also disrupt mating rituals and reproductive success in wildlife. Many animals have intricate courtship displays and specific acoustic signals that are integral to attracting mates. When noise levels are high, these delicate sounds may be obscured, reducing the chances of successful mating. For example, male songbirds may alter their songs or sing at higher volumes in noisy environments, potentially affecting their ability to attract female mates.
Additionally, some species have specific acoustic preferences for mating environments. They seek out locations with particular acoustic qualities that allow their mating calls to be heard clearly by potential partners. Noise pollution can degrade these habitats, reducing their attractiveness and suitability for reproduction.
Impact on Navigation and Space Use
Wildlife species also depend on natural sounds and acoustic cues for navigation and space use. They use sound to orient themselves, locate resources, and identify safe areas. Noise pollution can interfere with these processes, leading to disorientation and suboptimal habitat selection. For instance, bats use echolocation to navigate and find prey, but noise pollution can create acoustic barriers that hinder their ability to move freely and locate food sources effectively.
Moreover, noise pollution can also affect an animal's ability to assess risk and detect predators. In noisy environments, crucial auditory cues that signal danger may be masked, increasing their vulnerability to predation or other threats. This disruption can have cascading effects on wildlife behaviour, distribution, and overall survival rates.
The impact of noise pollution on wildlife communication, mating, and navigation is a growing area of ecological research. While some taxonomic groups, such as mammals, birds, and fishes, have been studied more extensively, there is still much to learn about the effects of noise on other species, including amphibians, reptiles, and invertebrates. By understanding these impacts, researchers can inform policies and decisions to reduce noise pollution and protect biodiversity.

Impact on marine life: echolocation, feeding, survival, etc
Marine life is heavily impacted by noise pollution, which affects echolocation, feeding, survival, and more.
Echolocation
Echolocation is a vital tool for many marine mammals, especially toothed whales like belugas and narwhals. These animals emit intense, high-frequency clicks and use the echoes to locate and capture prey, as well as to avoid obstacles. Noise pollution from human activities, such as shipping and oil exploration, can interfere with these signals. The high-frequency noises produced by ships and the intense noise of oil and gas exploration overlap with the hearing range of many marine mammals, disrupting their ability to echolocate.
Feeding
Noise pollution also affects the feeding habits of marine life. For example, in the Barents Sea, seismic surveys disrupted cod and herring migration routes, causing population declines as the fish failed to return to their traditional spawning and feeding grounds. Similarly, loud shipping noises around Californian shipping lanes have caused whales to abandon their critical feeding grounds, depriving them of essential nutrients.
Survival
Noise pollution can also threaten the survival of marine species. Many marine organisms depend on sound cues for migration, and noise pollution disrupts these navigational signals. As a result, animals may deviate from their natural migration routes, pushing them into regions with insufficient food or outside their thermal range. In some cases, they may be driven into more polluted waters, further exacerbating their challenges.
Communication and Mating
Marine mammals, such as baleen whales, use their hearing to communicate with each other and likely for orientation and navigation. Noise pollution can interfere with their ability to communicate effectively. It can also make it difficult for them to locate potential mates, threatening their survival as a species.
Stress and Hearing Loss
Exposure to intense noise from human activities can cause temporary or permanent hearing loss in marine animals. It can also lead to changes in stress hormone levels, further impacting their health and survival.

Sources: traffic, transport, construction, etc
Sources of noise pollution include traffic, transport, construction, industrial activities, aircraft, and railways.
Traffic
Traffic noise accounts for the most polluting noise in cities. For example, a car horn produces 90 dB, and a bus produces 100 dB. In comparison, a single aircraft produces 130 dB. However, there are fewer aircraft flying over cities than there are cars on the roads. A pneumatic drill used for road and pavement resurfacing produces 110 dB. Bars, restaurants, and terraces that spill outside can produce noise levels of more than 100 dB.
Transport
Long-term exposure to noise from transport has negative effects on health. Based on data reported in 2017, it is estimated that at least 18 million people are highly annoyed, and 5 million are highly sleep-disturbed due to long-term exposure to transport noise. The European Union's zero pollution action plan aims to reduce the share of people affected by transport noise by 30%.
Construction
Construction noise and vibration can affect people near the site and cause severe health issues. These include stress, poor concentration, productivity losses, communication difficulties, fatigue from lack of sleep, cardiovascular disease, cognitive impairment, tinnitus, and hearing loss. Construction noise can also damage surrounding buildings.
Other Sources
Industrial activities, aircraft, and railways are other significant sources of noise pollution. Living close to these sources of noise can lead to health issues such as annoyance, sleep disturbance, and cardiovascular and metabolic issues. More than half of the population in many cities is exposed to road noise levels above the World Health Organization guidelines for the day-evening-night period.

Solutions: noise reduction, noise management, noise awareness, etc
Noise pollution is one of the most dangerous environmental threats to health, according to the World Health Organization (WHO). It is linked to 12,000 premature deaths and 48,000 new cases of ischaemic heart disease every year. Noise becomes harmful when it exceeds 75 decibels (dB) and is painful above 120 dB.
Noise reduction
To reduce noise pollution, individuals can avoid very noisy leisure activities and opt for quieter means of transport, such as bicycles or electric vehicles. People can also do their housework at recommended times and insulate their homes with noise-absorbing materials.
Noise management
Local authorities and governments can adopt sound land use planning practices to monitor and manage noise in urban environments. They can also implement regulations that include preventive and corrective measures, such as mandatory separation between residential zones and sources of noise, and fines for exceeding noise limits.
Noise awareness
Awareness of noise pollution is essential to combat this issue. Educating the younger generation is an essential aspect of environmental education. Employers should also ensure that workers are aware of the hazards of excessive noise exposure and provide them with the necessary protective equipment, such as hearing protection devices, to safeguard their hearing.
Other solutions
Other solutions to reduce noise pollution include the use of noise barriers or insulation, particularly in inner-city areas where differing land uses are located in close proximity. Acoustic consultants can provide detailed guidance on the design and orientation of barriers to effectively mitigate noise. Additionally, vegetation can be used as a natural noise barrier, but only if the plantations are very dense.
