To me, noise pollution has no merits. Its demerits are :--
Premature deafness,
Lack of ability to hear important sounds clearly leading to
inability to hear oncoming danger
inability to hear common conversation
Tinnitus
Distortion of speech or music
Mental stress from the constant and unremitting noise.
Confusion
Deterioration of general health.
This is caused by constant traffic noise, workplace noise from machinery or processes used in manufacture and construction
Earphones
Loud music, stereos,
Airports, railways, including subway lines, busses, trucks, motorcycles and loud car exhaust.
