Comparative Study of Noise Pollution in Urban and Semi-Urban Areas: A Case Study of Mumbai and Nashik

Noise pollution is a growing environmental issue in Indian cities due to rapid urbanization and industrialization. This study presents a comparative analysis of noise pollution levels between Mumbai (metropolitan city) and Nashik (emerging tier-2 city). The research examines sources, measured sound levels, health impacts, and regulatory frameworks. Secondary data from environmental reports and monitoring studies indicate that Mumbai experiences significantly higher and continuous noise levels compared to Nashik, where noise is relatively lower but increasing. The study highlights the need for stricter enforcement of environmental regulations and sustainable urban planning.
