Noise pollution is defined as excessive noise that harms human activity or health. Common sources of noise pollution include vehicles, factories, aircraft, loud music, and shouting. Noise becomes pollution when it disturbs normal activities like sleep, work, and conversation. The effects of noise pollution include psychological stress, lack of concentration, fatigue, depression, interference with communication, and increased accident rates. Methods to reduce noise pollution include soundproofing, locating noisy machines away from living areas, banning loud vehicles, separating industrial and residential areas, establishing silence zones, and using vegetation to absorb sounds.
