dc.description.abstract In this thesis, we study road traffic noise at five different sites of the capital city of Ethiopia, Addis Ababa. These five sites are hospitals, courts, schools, commercial and residential areas. From these five sites, we have selected forty-six different places using simple random sampling techniques. The objective of this study is to evaluate the traffic noise level in some selected areas of Addis Ababa city. In this study, measurement of noise pollution was done by using sound level meter. Various parameters were evaluated e.g. Leq Level, L10 level and L90 level. The noise levels was measured under traffic conditions over different time span in Addis Ababa city, to estimate, whether these levels exceeds permissible limits, prescribed by the Ethiopian Environmental protection authority and WHO standard was used as a Guidance. The average Leq noise level was observed 67.29, 67.32, 64.12, 68.24 and 66.64 dB (A) in commercial areas, residential areas, courts, schools and hospitals respectively. However, the noiselevel in all areas are found to be above the prescribed limit of W.H.O. en_US
