Noise pollution: how to reduce the impact of an invisible threat?

Popular in: Environment / Water / Pollution

What is Noise Pollution?

Faisalabad is one of the major industrial cities of Pakistan, which may cause noise pollution to the local residents due to the development of robust industrial and transport systems. This study aimed at i mapping the noise pollution levels at various locations of Faisalabad city; ii comparing noise pollution levels in the morning, the afternoon, and the evening for each source; and iii assessing nonauditory effects of noise on human health.

Noise pollution: how to reduce the impact of an invisible threat?

Noise pollution , also known as environmental noise or sound pollution , is the propagation of noise with ranging impacts on the activity of human or animal life, most of them harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems. Some of the main sources of noise in residential areas include loud music , transportation traffic, rail, airplanes, etc. Documented problems associated with noise in urban environments go back as far as ancient Rome. High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease. Up until recently, most research on noise impacts has been focused on marine mammals, and to a lesser degree, fish. A variation in the complexity of their sensory systems exists, which allows scientists to study a range of characteristics and develop a better understanding of anthropogenic noise impacts on living organisms.

Noise pollution occurs when unwanted sounds enter the environment. The potential health effects of noise pollution include increased stress levels, sleep disturbance, or hearing damage. Some examples of noise pollution sources include :. This article looks at noise pollution in more detail and its potential health effects. We will also discuss ways to reduce noise pollution.

Exposure to prolonged or excessive noise has been shown to cause a range of health problems ranging from stress, poor concentration, productivity losses in the workplace, and communication difficulties and fatigue from lack of sleep, to more serious issues such as cardiovascular disease, cognitive impairment, tinnitus and hearing loss. This study collated data from various large-scale epidemiological studies of environmental noise in Western Europe, collected over a year period. The studies analysed environmental noise from planes, trains and vehicles, as well as other city sources, and then looked at links to health conditions such as cardiovascular disease, sleep disturbance, tinnitus, cognitive impairment in children, and annoyance.

Noise pollution , unwanted or excessive sound that can have deleterious effects on human health, wildlife, and environmental quality. Noise pollution is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highway, railway, and airplane traffic and from outdoor construction activities. Sound waves are vibrations of air molecules carried from a noise source to the ear. Sound is typically described in terms of the loudness amplitude and the pitch frequency of the wave. Loudness also called sound pressure level, or SPL is measured in logarithmic units called decibels dB. The normal human ear can detect sounds that range between 0 dB hearing threshold and about dB, with sounds between dB and dB causing pain pain threshold.

Noise pollution has become a major environmental problem leading to nuisances and health issues. This paper aims to study and analyse the noise pollution levels in major areas in Ota metropolis. A probability model which is capable of predicting the noise pollution level is also determined. Datasets on the noise pollution level in 41 locations across Ota metropolis were used in this research. The datasets were collected thrice per day; morning, afternoon and evening. Descriptive statistics were performed, and analysis of variance was also conducted using Minitab version


Noise pollution is a major problem in cities around the world. Noise represents an important public health problem that can lead to hearing loss, sleep disruption, cardiovascular disease, social handicaps, reduced productivity, negative social behaviour, annoyance reactions, absenteeism and accidents.


What is Noise Pollution?

Most of us are accustomed to the sounds we hear every day. However, when the sound of the television keeps you from sleeping all night or the traffic starts giving you a headache, it transcends the boundaries of mere noise and qualifies as noise pollution. However, the noise that tends to disrupt the natural rhythm of life makes for one of the biggest pollutants. By definition, noise pollution takes place when there is either an excessive amount of noise or an unpleasant sound that causes a temporary disruption in the natural balance. This definition is usually applicable to sounds or noises that are unnatural in either their volume or their production.

 Ja. Дверь слегка приоткрылась, и на него уставилось круглое немецкое лицо.

 Какой тип? - Беккер хмуро взглянул на полицейского. - Тот, что вызвал скорую. Он болтал что-то на ужаснейшем испанском, который мне только доводилось слышать. - Он сказал, что на руке у мистера Танкадо было кольцо. Офицер кивнул, достал из пачки Дукадо сигарету, посмотрел на плакат с надписью No fumar - Не курить - и все же закурил. - Наверное, я должен был обратить на это внимание, но тот тип показался мне настоящим психом.

Это была цифровая мультимедийная трансляция - всего пять кадров в секунду. На экране появились двое мужчин: один бледный, коротко стриженный, другой - светловолосый, с типично американской внешностью. Они сидели перед камерой наподобие телеведущих, ожидающих момента выхода в эфир. - Это что еще за чертовщина? - возмутился Джабба. - Сидите тихо, - приказал Фонтейн. Люди на экране вроде бы сидели в каком-то автобусе, а вокруг них повсюду тянулись провода. Включился звук, и послышался фоновой шум.

    Atmospheric pollution is not the only type of contamination that is harming living beings on the planet.
