Noise pollution, or sound pollution, is the propagation of noise or sound with ranging impacts on the activity of human or animal life, most of which are harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems.[1][2][3] Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Some of the main sources of noise in residential areas include loud music, transportation (traffic, rail, airplanes, etc.), lawn care maintenance, construction, electrical generators, wind turbines, explosions and people.
Documented problems associated with noise in urban environments go back as far as ancient Rome.[4] Research suggests that noise pollution in the United States is the highest in low-income and racial minority neighborhoods,[5] and noise pollution associated with household electricity generators is an emerging environmental degradation in many developing nations.[6]
High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease.[7][8] In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.[9]
