ABSTRACT
This study was carried out to assess the environmental noise pollution in the city of Khoramabad, Iran. On the basis of the resultant acoustic zoning 30 sites were selected for an experimental study. The main indices for noise pollution (Leq, L1, L10, L50 and L90) were measured. Results indicated that main streets of Khoramabad are overloaded during day-time. In all the sites average daily sound levels was 14 dB higher than environmental standards due to street traffic and peculiar geo-morphological structure of the town.
