Abstract
Noise pollution is a significant danger to urban life, affecting living and non-living things. It is becoming a more pervasive and unrecognized kind of environmental degradation, and after air and water pollution, it ranks as the third riskiest form of pollution. It is characterized as any sound pressure level of more than 55 dB, and prolonged exposure is bad for human health. Humans are mostly responsible for modifying the acoustic backdrop of the planet, and to reduce noise by 3 to 6 dB (A), noise barriers can be used. The primary cause of noise pollution, particularly in cities, is the rise in the number of automobiles, excessive honking, and traffic congestion.
Traffic noise is a result of vehicle movement on roadways, and numerous elements affect how loudly vehicles emit noise. Additionally, other kinds of noise pollution, such as industrial noise pollution and neighborhood noise pollution, can also have harmful effects on human health. The steps to reduce noise pollution include maintaining vehicles and roads, planting trees, using silencers for generators, controlling traffic movements, raising public awareness, and so on. This review paper provides a comprehensive overview of noise pollution and its effects on the urban environment. By understanding the sources, impacts, and potential mitigation strategies, policymakers, urban planners, and the public can take informed actions to reduce noise pollution and create more livable cities.
