ABSTRACT

Road traffic noise has increasing broader effects on urban areas as well as rural areas becauseof rapidly increasing traffic volume and newly-constructed roads. 10 sites in buildingdevelopment areas were selected and the noise level were measured by the apartment floorsand by the various block plans of apartment complex. Analysis result, about correction factor, in the case of right angle arrangement, apply -2.5dB(A). In the case of apartment house correlation of each floor apply 1st floors 0dB(A), 2stfloors 1.2dB(A), 3st floors 2.1dB(A), 4st floors 2.6dB(A), 5st floors 2.7dB(A), 6st floors 2.7dB(A),7st floors 2.4dB(A), 8st floors 2.0dB(A), 9st floors 1.6dB(A), 10st floors 1.1dB(A), 13st floors0.2dB(A), 15st floors 0.5dB(A). The level of road traffic noise in the arrangement construction ofright angle was about 3.0dB(A) at N-4 point and 2.1dB(A) at N-6 point lower than that of a plan figure, respectively. The results suggested that application of correction coefficient obtained by the apartment floor and by the arrangement construction can be improved in road traffic noise.
