Assessment of Noise Pollution in Central Nagpur

Abstract Urban noise pollution has become a pressing environmental concern, particularly due to its adverse effects on human well-being and quality of life. This study evaluates ambient noise levels in four key land-use zones—silence, residential, commercial, and transportation hubs within Central Nagpur. A total of 15 locations were systematically monitored across various times of the day (morning, afternoon, and evening) over a span of one week. The study involved computing essential acoustic indices such as Leq, Lmax, Lmin, L10, L50, L90, TNI, LNP, and Noise Climate (NC) to capture the noise characteristics comprehensively. The recorded values were assessed against the permissible limits set by the Central Pollution Control Board (CPCB). Results showed considerable exceedance in all zones, with the transportation and commercial areas reporting the highest average sound level, often exceeding 75 dB(A). Even designated silence zones, including hospital and educational areas, experienced noise levels beyond the CPCB threshold of 50 dB(A), indicating a serious breach of environmental standards. Time-based analysis revealed that noise levels peaked during typical traffic congestion hours in the morning and evening. This research highlights the widespread nature of noise pollution in urban Nagpur and emphasizes the need for tailored control strategies. These may include better traffic regulation, the use of sound barriers, stricter enforcement of noise norms, and enhanced public awareness. The outcomes offer crucial insights into sustainable urban management and future noise mitigation planning.
