Noise pollution is a serious issue that affects the health and well-being of both humans and wildlife. It is caused by unwanted or disturbing sounds that interfere with normal activities such as sleep or conversation, or disrupt and diminish one's quality of life. Sources of noise pollution include traffic, construction, aircraft, industrial machines, and loudspeakers, among others. The adverse effects of noise pollution include hearing loss, stress, high blood pressure, cardiovascular issues, and sleep disturbances. It is particularly harmful to vulnerable groups such as children, the elderly, and those on the autism spectrum. Additionally, noise pollution has been linked to environmental degradation and the disruption of breeding cycles in wildlife.

What You'll Learn
Hearing loss
Noise pollution is a significant issue that affects the lives of millions of people, causing a range of problems, including hearing loss. Hearing loss, specifically Noise-Induced Hearing Loss (NIHL), is one of the most common and widely discussed adverse health effects of noise pollution. It occurs when the human ear is constantly exposed to loud noises beyond the range that the eardrum can withstand, resulting in damage and subsequent hearing impairment.
The impact of noise pollution on hearing loss is well-documented, with research indicating that industrial noise pollution can cause a 20% reduction in hearing ability. This is particularly prevalent in industrial areas, where the use of heavy machinery, such as generators, mills, and huge exhaust fans, produces excessive noise. Vehicular traffic, including cars, buses, and aircraft, also contributes significantly to noise pollution, with aircraft producing up to 130 dB of noise.
The World Health Organization (WHO) has established guidelines for safe noise levels, recommending a maximum of 30 dB. However, noise levels in many urban environments often exceed this limit, leading to harmful effects on hearing. For example, exposure to sound levels above 85 dB can cause Noise-Induced Hearing Loss. This is particularly concerning for individuals who live near airports or busy streets, as their prolonged exposure to high noise levels can lead to irreversible hearing damage.
The impact of noise pollution on hearing loss is not limited to humans. Marine ecosystems are also affected, with at least 55 marine species, including whales and dolphins, suffering from auditory damage due to human activities such as construction, shipping, and the use of sonar devices. These marine mammals rely on echolocation for communication, navigation, and feeding, and noise pollution interferes with their ability to effectively echolocate, impacting their survival.
The adverse effects of noise pollution on hearing loss have led to increased awareness and efforts to mitigate its impact. Individuals can protect themselves by using hearing protection, such as earplugs or earmuffs, especially when exposed to loud sounds. Additionally, noise pollution prevention strategies, such as dense tree cover and the use of noise-absorbing materials in construction, can help reduce the impact of noise on hearing health.

Cardiovascular issues
Noise pollution has been linked to a range of cardiovascular issues, with studies showing a clear association between noise and various adverse effects on heart health. The impact of noise on cardiovascular health is an increasingly recognised issue, with noise now considered a significant risk factor for cardiovascular illness.
One of the primary ways in which noise pollution affects cardiovascular health is by causing chronic stress. Noise activates the sympathetic nervous system, leading to the release of stress hormones such as cortisol, adrenaline, and noradrenaline. This, in turn, can cause damage to the inner lining of blood vessels, a condition known as endothelial dysfunction, which is a contributing factor to cardiovascular disease. Chronic stress can also cause inflammation and changes in the blood vessels associated with heart disease.
In addition, noise pollution has been found to disturb sleep, which can have detrimental effects on cardiovascular health. Studies have shown that noise-induced reduction and fragmentation of sleep can increase the risk of cardiovascular disease. Specifically, chronic night-time exposure to noise pollution, even at relatively low volumes, can negatively impact heart health. A 2015 meta-analysis found a positive correlation between the level of chronic exposure to transportation noise and the risk of coronary artery disease.
Furthermore, noise pollution has been associated with an increased incidence of arterial hypertension, myocardial infarction, and stroke. Aircraft noise, in particular, has been linked to a higher risk of cardiovascular disorders, with residents living near airports experiencing higher rates of stroke and coronary heart disease. Road traffic noise has also been associated with myocardial infarctions, with one study finding a significant relationship between noise exposure and the occurrence of heart attacks, independent of air pollutant levels.
The negative impact of noise on cardiovascular health is not limited to direct physiological effects. Noise can also cause annoyance and emotional distress, including anxiety and depression, which may indirectly impact cardiovascular health. Overall, noise pollution is a significant contributor to cardiovascular issues, and effective preventive measures are needed to mitigate its harmful effects on heart health.

Sleep disturbances
The World Health Organization (WHO) defines noise as sound that is unwanted or disturbing, which, at a certain volume, can cause harm to human health. According to the WHO, the recommended noise level should be no more than 30 dB, while noise above 45 dB can prevent people from falling asleep or sleeping properly.
Noise pollution is a common issue that impacts the lives of millions of people, causing a range of problems, including sleep disturbances. Sleep is essential for maintaining good physical and mental health, and disruptions to sleep cycles can lead to a variety of negative consequences.
Noise pollution can lead to sleep disturbances in several ways. Firstly, it can make it difficult for people to fall asleep or cause them to wake up multiple times throughout the night. This sleep fragmentation results in non-restorative sleep, leaving individuals feeling tired and lacking energy during the day. It can also cause a reduction in the overall sleep duration, leading to sleep deprivation, which has been linked to various health issues.
Additionally, noise pollution can impact the quality of sleep by interfering with different stages of the sleep cycle. For example, loud noises during the deeper stages of sleep can startle individuals awake or cause them to shift to lighter stages of sleep, preventing them from getting the full benefits of a good night's rest. This can lead to increased irritability, fatigue, and difficulty concentrating during the day.
The impact of noise pollution on sleep can vary depending on individual factors such as age, with children and older individuals being particularly vulnerable. Children living in noisy environments have been found to experience stress and impairments in memory, attention, and reading skills. For older individuals, the constant exposure to loud noise can lead to hearing loss, making it even more challenging to get a restful night's sleep.
To mitigate the effects of noise pollution on sleep, it is essential to implement preventive measures. This can include avoiding noisy activities, opting for quieter means of transportation, doing household chores at recommended times, and using noise-absorbing materials to insulate homes. By reducing noise pollution and creating quieter environments, individuals can improve their sleep quality and overall health and well-being.

Stress and irritability
Noise pollution, which occurs when unwanted sounds enter the environment, can have a significant impact on the well-being of humans and animals. It can cause stress and irritability in several ways. Firstly, it activates the body's stress response system, leading to increased stress hormone levels and potential mental health issues such as anxiety and depression. This chronic activation of the stress response can wear down the body over time, causing both mental and physical health problems.
Research has shown that noise pollution can cause elevated stress levels, with one study finding that a 10-decibel increase in aircraft noise was associated with a 28% increase in anxiety medication use. Another study found that people in noisier areas were 25% more likely to have depressive symptoms. Noise pollution can also affect children's cognitive growth and language skills, leading to increased anxiety and impaired resilience.
The constant presence of unwanted noise can be a threat to concentration and productivity, causing irritability and annoyance. This is true in both the workplace, where noise can decrease the productivity of those around us, and at home, where a constantly running TV or other noises can impact our ability to focus.
Chronic stress caused by noise pollution can also lead to impaired cognitive functioning and increased susceptibility to disease. It can cause sleep disturbances, preventing deep sleep and disrupting sleep cycles, which is essential for vascular repair and can impact overall health.
Overall, noise pollution can cause stress and irritability through its impact on the body's stress response system, mental health, concentration, sleep, and overall well-being.

Negative impact on wildlife
Noise pollution has a detrimental impact on wildlife, affecting their health and well-being. It is a growing concern for environmental health, threatening the ecological balance of an area. Wildlife is vulnerable to the adverse effects of noise pollution, as many animals rely on their sense of sound for survival.
Noise pollution can cause hearing loss in animals, as well as increase their stress levels. It can also lead to behavioural changes, impacting their natural activities such as finding food, communicating, navigating, mating, and avoiding predators. For example, research has shown that male frogs are adapting to traffic noise by calling at a higher pitch, which may be less attractive to females who prefer lower-pitched calls. Similar changes have been observed in multiple bird species, as well as squirrels, primates, bats, and cetaceans.
Marine life is particularly vulnerable to noise pollution due to the quick transmission of sound in water. Whales and dolphins, which depend on echolocation to communicate, navigate, and find prey, are greatly impacted by noise from ships, oil drills, and sonar devices. Sonar sounds can be extremely loud and travel long distances underwater, interfering with the ability of marine mammals to echolocate. This interference can lead to mass strandings of whales and altered feeding behaviours, putting already endangered species at further risk.
Noise pollution can also reduce the size of the area in which predators can hear their prey, impacting their hunting abilities. It can further cause neurobehavioral alterations in animals, negatively influencing their perception of stimuli and sense of orientation. For example, cuttlefish change their visual cues when exposed to noise, and noise pollution can also alter the defensive mechanisms of invertebrates against egg predators and the maintenance of their territory.
Overall, noise pollution has far-reaching consequences for wildlife, affecting their health, behaviour, and ability to survive. It is a pressing issue that requires careful consideration and efforts to curb its impact on ecosystems and biodiversity.
