Abstract
Present study focuses on typical noise assessment at 29 key locations in an academic area of a college during academic and non-academic hours, and comparison with Indian standards for sensitive zone. The equivalent continuous noise levels (L_Aeq) were observed to be exceeding the permissible limits of 50 dB L_Aeq during day time and 40 dB during night time on weekday as well as weekend of classrooms, corridors, central workshop and open spaces in academic area. The average L_Aeq values for the entire academic area on weekday during day time (65.88 dB), weekday night time (47.70 dB), weekend day time (57.73 dB) and weekend night time (45.77 dB) were also observed to be 31.77 %, 19.24 %, 15.45 % and 14.43 % respectively higher than the prescribed standards for educational/ academic institutes. Further, noise maps were created by ArcGIS using Inverse Distance Weighting (IDW) technique showing noise hotspots at a glance.
