Abstract (AI)
Noise pollution, in the recent times, has been well recognized as one of the major trepidations that impact the quality of life in urban areas across the globe. Kolhapur, an ancient city of India, is rapidly emerging as industrialized and urbanized city and has started facing severe noise pollution problems. Day-time urban noise quality assessment was studied in Kolhapur for five critical zones viz. Educational, Commercial-cum-residential, Industrial-cum-residential, Recreational and Silence zone. Noise pollution indices viz. L10, L50, L90, noise climate (NC), equivalent continuous noise level (Leq), noise pollution level (Lnp) and noise exposure index (NEI) were computed for all zones. Results indicated that the highest Leq of 72.25 dBA was observed in industrial-cum-residential zone followed by 64.47 dBA in commercial-cum-residential zone, 63.71 dBA in educational zone, 53.26 dBA in recreational zone and 42.84 dBA in silence zone. For educational zone, Leq observed were above the statutory limits, while for other zones it was marginally below. The noise assessment study clearly revealed the alarming condition of noise pollution in Kolhapur.
Key Findings
1
Day-time noise quality was assessed in Kolhapur across five zones: Educational, Commercial-cum-residential, Industrial-cum-residential, Recreational, and Silence zone.
2
Educational zone Leq was 63.71 dBA and exceeded statutory limits for that zone.
3
Highest Leq recorded was 72.25 dBA in the Industrial-cum-residential zone, the next highest 64.47 dBA in Commercial-cum-residential zone.
4
Noise indices computed included L10, L50, L90, Noise Climate (NC), equivalent continuous noise level (Leq), Noise Pollution Level (Lnp), and Noise Exposure Index (NEI).
5
Overall assessment indicates an alarming condition of noise pollution in Kolhapur associated with rapid industrialization and urbanization.
6
Recreational and Silence zones had Leq values of 53.26 dBA and 42.84 dBA respectively, marginally below statutory limits for non-educational zones.
