Evaluating the Level of Noise Pollution in the Town of Jamalpur, Bangladesh

The study aimed to assess the extent of noise pollution in different areas within Jamalpur District Town. REED SD-4023 was used to measure noise levels from various sampling sites from January 1, 2021, to April 30, 2021. Several samples were collected from each sampling site. Every place's noise level measurement has been taken three times a day. Based on land uses, Jamalpur District Town was divided into 7 different zones and 60 places. The mean noise level and Leq were found to be 72.19 dBA and 94.36 dBA. The mean noise level and Leq for the Silent Area, Residential Area, Mixed Areas, Commercial Area, Industrial Area, Road Intersection, and Village Area were 69.70 dBA and 84.38 dBA; 70.78 dBA and 91.96 dBA; 77.28 dBA and 86.31 dBA; 77.27 dBA and 89.28 dBA; 70.56 dBA and 82.91 dBA; 79.12 dBA and 102.42 dBA; and 60.64 dBA and 93.25 dBA. The hierarchy of various land uses according to mean noise levels was road intersections > mixed areas > commercial areas > residential areas > industrial areas > silent areas > village areas. The three major areas with the highest levels of noise pollution were Foujdari Mor (107.72 dBA), Tennis Club Mor (107.39 dBA), and South Kachari Para (102.63 dBA).
