Abstract

Actually, prediction formula of road traffic noise for EIA(Environmental Impact Assessment)has been used that proposed by National Institute of Environmental Research in 1999. Theprediction formula, however, was calculated predicted noise level according to noise levelproducing on first floor, then needs to correct noise level at each floor in the case of apartmentbuilding. The investigation was carried out to calculate the correction coefficient for commonlyusing in EIA of large scaled apartment development areas. The noised level at each floor weremeasured from August 2001 to March 2002 at 31 investigation points of large scaled apartmentdevelopment area in national wide. Measured data were divided and treated with 4 types as3th floor, 5th floor, 7th floor and 10th floor and then the correction coefficients of each floorwere calculated using by correlation formula according to each floor.
