Rapid urbanization and population growth in Chandigarh, India, have resulted in increased noise pollution levels, affecting the quality of life for its residents. This research paper aims to conduct a comprehensive analysis and noise mapping of Chandigarh City. In this study 25 monitoring sites throughout Chandigarh township were utilised to analyse traffic noise using noise descriptors (L10, L50, L90, NC, TNI and NPL). The hourly equivalent noise levels of 25 sites were monitored at peak morning hours (9AM-11AM) and peak evening hours (5PM-7PM) to analyse the environmental noise pollution scenario in the city. The study utilizes geographic information systems (GIS) to create a detailed noise map, identifying critical noise sources and providing insights for effective noise control strategies. A socio-acoustic survey conducted to analyse the public perception towards noise pollution and associated health hazards. The findings of this research can assist policymakers, urban planners, and environmentalists in developing sustainable urban development plans and mitigating the adverse effects of noise pollution.

The study utilizes geographic information systems (GIS) to create a detailed noise map, identifying critical noise sources and providing insights for effective noise control strategies. A socio-acoustic survey conducted to analyse the public perception towards noise pollution and associated health hazards. The findings of this research can assist policymakers, urban planners, and environmentalists in developing sustainable urban development plans and mitigating the adverse effects of noise pollution.
