Health effects on humans
Noise pollution is any unwanted or excessive sound that can have harmful effects on human health, wildlife, and environmental quality. It is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highways, railways, airplanes, outdoor construction activities, and transportation systems.
Noise pollution has been deemed a "growing danger to the health and welfare of the Nation's population." It is the second largest environmental cause of health problems, just after air pollution. Noise pollution has been linked to several health issues, including:
- Hearing Loss: Exposure to loud noise can lead to temporary or permanent hearing loss, known as Noise-Induced Hearing Loss (NIHL). Sounds that reach 85 decibels or higher are considered potentially harmful, and NIHL is the most common health problem caused by noise pollution. Approximately 10 million people in the US have permanent hearing loss due to noise or trauma.
- Cardiovascular Issues: Research has shown that noise pollution can cause or exacerbate cardiovascular disease, heart disease, high blood pressure, and hypertension. Chronic noise exposure contributes to an estimated 48,000 new cases of heart disease in Europe each year.
- Sleep Disturbances: Noise can interfere with sleep, with 6.5 million people in Europe experiencing sleep disruption due to noise. This can lead to increased stress levels, mood swings, and diminished productivity.
- Stress and Mental Health: Noise pollution has been linked to elevated stress levels, anxiety, irritability, mental fatigue, and cognitive decline. It can also cause or worsen mental health problems and impair memory and attention.
- Speech and Language Development: Noise pollution can interfere with speech and language development, particularly in children. Loud noises can make it difficult to hear and understand speech, impacting communication and learning.
- Physical Health: Exposure to loud noise can cause physical damage to the eardrum and the sensitive hair cells of the inner ear. It can also lead to tinnitus and hypersensitivity to sound.
Noise-induced illnesses are a significant concern, and researchers are working to better understand the mechanisms and magnitude of these health effects to improve patient care and implement effective noise pollution control measures.

Impact on wildlife
Noise pollution, or sound pollution, refers to unwanted or disturbing sounds that have the potential to harm humans, animals, and the environment. It is caused by a variety of sources, including machines, transportation systems, industrial facilities, construction, and more. Noise pollution is not only limited to land but also affects marine life.
Noise pollution has significant impacts on wildlife, affecting a wide range of animals, from insects and birds to marine mammals. One of the most affected senses in many animals is their sense of hearing, which is crucial for survival. In marine ecosystems, noise pollution affects at least 55 species. Marine animals, such as whales and dolphins, rely on echolocation for communication, navigation, feeding, and finding mates. Excessive noise from ships, seismic tests, oil drills, and naval sonar devices interferes with their ability to echolocate effectively. The loudest underwater noises, such as those from sonar devices, can reach 235 decibels and travel for hundreds of miles, causing severe disruptions to marine life.
Birds are also significantly impacted by noise pollution. In urban environments, birds like European robins are more likely to sing at night due to high noise levels during the day. This change in behaviour can have evolutionary consequences, as it may alter mating preferences and selection traits. Additionally, noise pollution has been found to reduce the species richness of birds in Neotropical urban parks.
Noise pollution can also interfere with the ability of animals to attract mates, communicate, navigate, find food, and avoid predators. For example, research has shown that male frogs adapt to traffic noise by calling at a higher pitch, which may be less attractive to females who prefer lower-pitched calls. In some cases, noise pollution can even pose an existential threat to vulnerable organisms, as their ability to survive and reproduce is hindered.
The impact of noise pollution on wildlife is a growing concern, with over 800 peer-reviewed studies published on the topic. It is important to carefully consider the effects of human-generated noise on ecosystems and implement measures to protect wildlife from these disturbances.

Sources of noise pollution
Noise pollution is caused by unwanted or excessive sound that can have harmful effects on human health, wildlife, and environmental quality. It is commonly generated inside industrial facilities and other workplaces, but it also comes from traffic, construction, and transportation systems.
Industrial Facilities and Workplaces
Industrial noise pollution is produced by heavy machinery such as generators, mills, and large exhaust fans. Industrial machines can generate loud, high-intensity sounds that damage hearing ability and cause other health issues.
Transportation and Traffic
Traffic noise is a significant source of noise pollution in cities, with vehicles, aircraft, and road construction contributing to the problem. A single car horn produces 90 dB, while a bus produces 100 dB. Aircraft flying over cities produce even higher levels of noise, with a single aircraft generating 130 dB.
Construction
Building and road construction, as well as pavement resurfacing, are major sources of noise pollution. Pneumatic drills, for example, produce 110 dB of noise.
Entertainment and Hospitality Venues
Bars, restaurants, pubs, and clubs that operate outdoors or have spillover noise can produce more than 100 dB of noise.
Residential Areas
In residential areas, noise pollution can come from loud music, lawn care maintenance, electrical generators, wind turbines, and people. Poor urban planning, such as side-by-side industrial and residential buildings, can also contribute to noise pollution in these areas.
Ocean and Marine Sources
Noise pollution in the ocean is a serious issue for marine animals, especially those that rely on echolocation, such as whales and dolphins. Ship traffic, seismic tests, and oil drilling create chaotic sounds that interfere with the survival and communication of marine life.
Noise pollution has various sources that impact both human health and the well-being of wildlife and ecosystems. These sources often overlap and combine to create elevated noise levels, causing adverse effects on health, behaviour, and the environment.

Solutions to noise pollution
Noise pollution is a serious issue that can have far-reaching consequences for both human health and the environment. It is defined as any unwanted or disturbing sound that exceeds 75 decibels and has the potential to harm humans and animals. The sources of outdoor noise worldwide are mainly caused by machines, transport, and propagation systems. As noise pollution is such a pervasive issue, it is important to consider a variety of solutions to mitigate its impact.
One way to reduce noise pollution is to implement stricter regulations and enforcement. This includes establishing laws that mandate separation between residential zones and sources of noise, such as airports, and imposing fines for exceeding noise limits. Governments have a crucial role in ensuring correct noise management and can protect certain areas, such as natural parks, from excessive noise.
Another solution is to focus on improved building methods and better product design. This involves designing buildings with soundproofing materials and techniques, as well as incorporating noise barriers and better urban planning. Side-by-side industrial and residential buildings can result in noise pollution in residential areas, so careful planning is essential.
In addition to regulatory and design solutions, promoting community awareness and education about noise pollution is vital. This includes encouraging the use of alternative means of transport, such as bicycles or electric vehicles, and recommending noise-reducing practices like the use of noise-absorbing materials in homes and the insulation of homes. Educating the younger generation about noise pollution is an essential aspect of environmental education.
Furthermore, natural solutions can also be effective in mitigating noise pollution. Planting trees and creating more green spaces can act as natural sound buffers, helping to reduce the impact of noise in populated areas.
By combining regulatory measures, improved design practices, community education, and natural solutions, we can effectively address the issue of noise pollution and minimize its impact on human health and the environment.

How noise is measured
Noise pollution is defined as "the presence in the environment of noise or vibrations, whatever the acoustic emitter that originates them, which implies annoyance, risk or damage to people, to the development of their activities or to goods of any nature". It is commonly generated inside many industrial facilities and some other workplaces, but it can also come from road, rail, and air traffic, as well as construction activities.
The main unit used to measure the intensity or loudness of sound is the decibel (dB). The normal human ear can detect sounds that range between 0 dB (hearing threshold) and about 140 dB, with sounds between 120 dB and 140 dB causing pain. An increase of 10 dB represents a ten-fold increase in sound intensity, while an increase of 30 dB represents a 1,000-fold increase in intensity. Decibels can be adjusted to human hearing and are described in decibels A (dBA). A-weighting adjusts sound measurements for the frequencies heard in human speech.
Sound can also be measured by its pitch, or frequency, which is the number of sound waves propagated through the air per second. Pitch is measured in Hertz (Hz) and the range of frequencies heard by the human ear range from 20 Hz to 20,000 Hz. However, sensitivity to hearing higher frequencies decreases with age.
Noise immission refers to the reception and exposure to noise generated by an emitting source. It is measured in decibels and is used to assess the noise levels to which a person or community is exposed.
There are two types of sound level meter: Class 1 and Class 2. A Class 1 sound level meter is considered more accurate than a Class 2 sound level meter due to its narrower tolerance limits. These environmental noise meters are used to conduct acoustic surveys in urban, industrial, traffic, and residential areas to assess noise indices and determine whether or not they comply with regulations. Smartphone apps have also been developed to measure sound levels, such as the NIOSH Sound Level Meter App.
