This GIS based case study work was carried out to environment friendly exposure condition at various location of Sylhet city. Sound level Meter (SLM) was used for assesses the noise level condition and noise mapping was done using Geographic Information System (GIS) technique. The Department of Environment (DOE), Bangladesh standards were used as limits for the designated land uses. A total number of 44 noise monitoring stations were selected for the collection of data classified based on commercial, residential and mixed areas. Noise recordings were conducted using morning, noon and evening periods of the day. From the study, it was observed that the overall sound level condition of the Sylhet city is unsafe in different locations for human health and it exceeds the noise standards established by the Department of Environment (DOE), Bangladesh.
