Abstract

Noise assessment is carried out in various residential, commercial and industrial places in and around Belpahar and Brajarajnagar of Ib River coalfield. The average noise intensities at various residential places range from 57.10 to 63.25 dB during day time (6 am-10 pm) and from 46.77 to 56.22 dB during night (10 pm-6 am). It clearly demonstrates that the noise levels are in close proximity or beyond the permissible limit. Though the average noise intensities at various commercial and industrial places are within the permissible limit, the Lmax noise values are more than the permissible limit. Analysis of variance is also computed for different residential, commercial and industrial places to infer the level of significance.
