Full information about noise pollution
Answers
Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with harmful impact on the activity of human or animal life. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems.[1][2] Poor urban planning may give rise to noise 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 noise, lawn care maintenance, nearby construction, or young people yelling (sports games). Noise pollution associated with household electricity generators is an emerging environmental degradation in many developing nations. The average noise level of 97.60 dB obtained exceeded the WHO value of 50 dB allowed for residential areas.[3] Research suggests that noise pollution is the highest in low-income and racial minority neighborhoods.[4] Documented problems associated with urban environment noise go back as far as ancient Rome.[5]
High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease.[6][7] 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.[8] While the elderly may have cardiac problems due to noise, according to the World Health Organization, children are especially vulnerable to noise, and the effects that noise has on children may be permanent.[9] Noise poses a serious threat to a child’s physical and psychological health, and may negatively interfere with a child's learning and behavior.[
Noise pollution is generally defined as regular exposure to elevated sound levels that may lead to adverse effects in humans or other living organisms. According to the World Health Organization, sound levels less than 70 dB are not damaging to living organisms, regardless of how long or consistent the exposure is. Exposure for more than 8 hours to constant noise beyond 85 dB may be hazardous. If you work for 8 hours daily in close proximity to a busy road or highway, you are very likely exposed to traffic noise pollution around 85dB.
This type of pollution is so omnipresent in today’s society that we often fail to even notice it anymore:
street traffic sounds from cars, buses, pedestrians, ambulances etc.
construction sounds like drilling or other heavy machinery in operation
airports, with constant elevated sounds from air traffic, i.e. planes taking off or landing
workplace sounds
often common in open-space offices
constant loud music in
near commercial venues
industrial sounds like fans, generators, compressor, mills
train stations traffic
