Question

Relevance of. Noise pollution

Answer 1

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

Answer 2

Answer:

Noise Pollution

Noise pollution also known as environmental noise means any unwanted or excessive sound that can have detrimental effects on the quality of life of humans. Noise pollution is the propagation of noise with a harmful impact on human and animal life. Noise pollution is commonly generated inside many industrial facilities. It also comes from highways, railways, air traffic, and outdoor construction activities.

Negative Effects or Consequences:

Unwanted sound (noise) can damage physiological health. Noise pollution can cause hypertension, high stress levels, hearing loss, sleep disturbances, and other disturbing effects. Prolonged high levels of noise can cause hearing loss and several other stress-related illnesses. Noise often affects children more than adults. In short, noise pollution affects our entire general well-being.

Preventive Measures:

• We can reduce noise pollution by turning off appliances when not in use or turning the volume of devices that produce high noise.
• Aircraft engines and automobile engines should be fitted with silencers to reduce the noise.
• Factories should be relocated away from residential areas.
• More trees should be planted along the roads because trees absorb noise.
