Noise pollution is defined as unwanted or excessive sound that has the potential to cause harmful effects on humans, wildlife, and environmental quality. Sources of noise pollution include machines, transport, and propagation systems, as well as industrial facilities and workplaces. The impact of noise pollution on humans includes hearing loss, high blood pressure, stress, and sleep disturbances. It can also affect children's learning and behaviour, with studies showing links between noise and impairments in memory, attention, and reading skills. Additionally, noise pollution poses a threat to wildlife, particularly marine animals such as whales and dolphins, which rely on echolocation for survival. The increase in anthropogenic noise has been shown to negatively impact the survival and behaviour of various species, including birds, amphibians, and marine creatures. Addressing noise pollution requires societal-level reforms, improved urban planning, and individual efforts to minimise noise footprints.

Noise pollution's impact on human health
Noise pollution is 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, and airplanes.
Noise pollution can cause several health problems for humans, and its impact on health is far-reaching. The most common health problem it causes is Noise-Induced Hearing Loss (NIHL). Exposure to loud noise can damage the eardrum and the sensitive hair cells of the inner ear, resulting in temporary or permanent hearing loss. According to a research article, exposure to sound levels above 81 dB increases the chances of hypertension in the local population.
Noise pollution can also cause high blood pressure, heart disease, sleep disturbances, stress, irritability, anxiety, mental fatigue, and interfere with personal communication. These health problems can affect all age groups, especially children. Many children who live near noisy airports or busy streets have been found to suffer from stress and other issues, such as impairments in memory, attention span, reading skills, and behaviour. The effects of noise on children may even be permanent.
The World Health Organization (WHO) has stated that noise is an "underestimated threat", and research by the House of Lords Science and Technology Committee in the UK found that noise pollution from traffic resulted in one million healthy life years lost in Western Europe per year. In 2018, 130,000 healthy life years were lost in the UK alone due to noise pollution, and 40% of the British population were exposed to harmful noise levels from road traffic.
Noise pollution is a serious issue that can have significant impacts on human health, and it is important to implement effective measures to reduce and regulate it to protect public health.

Its effects on wildlife and biodiversity
Noise pollution, or sound pollution, is 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.
Effects on Wildlife and Biodiversity:
Noise pollution has been shown to have adverse effects on wildlife and biodiversity. A wide range of animals, including insects, frogs, birds, and bats, rely on sound for various reasons, including attracting mates, communication, navigation, finding food, and avoiding predators. Noise pollution can interfere with these abilities, threatening the survival of vulnerable organisms.
Marine animals are particularly vulnerable to the impacts of noise pollution. Whales and dolphins, for example, rely on echolocation to communicate, navigate, feed, and find mates. Excess noise from ships, oil drills, seismic tests, and sonar devices interferes with their ability to echolocate effectively. Sonar sounds, in particular, can be extremely loud and travel hundreds of miles underwater, significantly impacting the ability of marine mammals to communicate and navigate.
Noise pollution can also cause stress in animals, with studies indicating that animals, like humans, experience stress in noisy environments. For example, the endangered Sonoran pronghorn avoids areas frequented by loud military jets, and female frogs exposed to traffic noise have more difficulty locating male mating signals. Noise pollution can also lead to behavioural changes, such as altered foraging behaviour, and even territory abandonment and loss of reproduction.
Additionally, noise pollution can increase the risk of death for some species by modifying the delicate balance between predators and prey. For instance, in areas with high air traffic, sound levels can be elevated by up to 5 decibels, resulting in a reduction of up to 70% in the size of the area where predators can hear their prey.
The impacts of noise pollution on wildlife and biodiversity are complex and vary depending on the species and the characteristics of the noise. However, the growing body of research highlights the need to carefully consider the effects of human-generated noise on ecosystems and to implement measures to protect vulnerable species.

Sources of noise pollution
Noise pollution, or sound pollution, is the presence of excessive or unwanted sound that can have harmful effects on humans, animals, and the environment. It is a growing concern in urban areas and has significant impacts on human health, wildlife, and the natural balance of ecosystems. The sources of noise pollution can be categorised into industrial and non-industrial, with the latter further divided into natural and man-made.
Industrial Sources
Industrial sources of noise pollution include noise from various industries and large machines operating at high speed and high noise intensity. This includes machinery and equipment used in construction, mining, and manufacturing, such as heavy machinery, power tools, fans, motors, compressors, and generators. Locomotive engines, horns, whistles, and switching operations in rail yards also contribute to noise pollution.
Non-Industrial Sources
Man-made
Transportation is a significant source of noise pollution, particularly in urban areas. This includes noise from cars, trucks, buses, motorcycles, aircraft, and rail systems. In residential areas, loud music, noisy parties, barking dogs, and lawn care maintenance can also contribute to noise pollution. Additionally, fireworks during festivals and celebrations can lead to both air and noise pollution and may cause non-recoverable hearing loss.
Natural
While less common, natural sources of noise pollution include animals such as barking dogs, chirping birds, or crowing cockerels, especially at night.

How to measure noise levels
Noise pollution is a growing environmental problem that can have adverse effects on human health. To measure noise levels, the decibel (dB) is the unit used to quantify the intensity of a sound. The decibel scale measures noise logarithmically, which is similar to how our ears perceive sound. For example, a sound 10 times more powerful than 0 dB is 10 dB, and a sound 100 times more powerful than 0 dB is 20 dB. Common sounds, such as a whisper, are around 30 dB, while a normal conversation is about 60-68 dB. This 68 dB level is generally considered safe for human hearing.
To measure noise levels, you can use a dedicated sound level meter (SLM) or dosimeter, which will give you a precise reading in decibels. There are different classes of SLMs, with Class 1 being the most accurate and suitable for laboratory settings, while Class 2 is slightly less precise but still suitable for general sound measurements. Anything below Class 2 is not recommended for accurate measurements. When using an SLM, you can point the microphone directly at the noise source or consult the manufacturer's instructions. Additionally, some SLMs have advanced features that allow for slower speed or interval measurements to capture intermittent sounds.
If you don't have access to an SLM, there are sound measurement apps available for smartphones that can provide a decent estimate of noise levels. Apps like SPL Meter (free), Decibel X (paid), and Too Noisy Pro (paid) are top-rated options for both Android and iOS devices. These apps can be useful for quickly assessing noise levels in various environments, such as concerts, sporting events, or workplaces. However, it's important to note that app measurements may not comply with regulatory requirements.
In the context of noise pollution, it's essential to understand the concept of noise immission, which refers to the reception and exposure to noise generated by an emitting source. Noise immission is also measured in decibels and is used to assess the impact of noise on individuals or communities. To address noise pollution, the focus is on reducing noise emissions at the source and protecting people from excessive noise immission. This responsibility falls on local governments and authorities, who create noise maps and enforce regulations to control noise levels.
