Notice on environment pollution
Answers
Explanation:
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 or near commercial venues
industrial sounds like fans, generators, compressor, mills
train stations traffic
household sounds, from the television set to music playing on the stereo or computer, vacuum cleaners, fans and coolers, washing machines, dishwashers, lawnmowers etc.
events involving fireworks, firecrackers, loudspeakers etc.
conflicts generate noise pollution through explosions, gunfire etc. The dysfunctions, in this case, are likely caused by the conflict and insecurity and less by the noise pollution in itself, although that compounds stress levels too.
