Abstract
There has been a raising concern about the steep increase in noise pollution in urban areas, caused by motor vehicles, construction, commercial activities, hotels and restaurants and use of loudspeakers at festivals and processions. Noise is a byproduct of human activities and most widespread source of noise pollution is transport. The noise from road traffic far exceeds that of railways, aircraft and industry sources. Multiplying motor vehicles population in urban areas leads to not only congestion on roads, but also excessive emissions of carbon dioxide (CO2); it has become a major source of noise pollution. The specific health effects of noise pollution include sleep disturbances, cognitive impairment in children and negative effects on the cardiovascular and metabolic systems. The present study attempted to compare levels of noise and air pollution in major cities of India, namely Hyderabad, Chennai, Delhi, Kolkatta, Bengaluru, Mumbai and Lucknow over a period of 11 years from 2011 to 2021. The study is based on secondary data published by the Central Pollution Control Board of India (CPCB) under National Ambient Noise Monitoring Network. The noise pollution has been compared among three zones, such as commercial, industrial and residential zones with permissible limits. It also compared the levels of noise pollution with the number of automobiles registered.
