Abstract
This study aims to derive the effect of road traffic noise perception by the visual and aural information through a laboratory experiment. To verify the result more precisely, ME(Magnitude Estimation) and SD(Semantic Differential Method) evaluation on the effect of visual and aural effect were carried out by 43 university students. As the result, up to 10% of psychological reduction effect was shown under the 65dB(A). As the noise level, it was analyzed that the vision affected about 7dB(A) and sound affected 5dB(A). However, if these two are given simultaneously, mainly sound affects to reduce the annoyance of noise and the vision next. Compared with the urban central circumstances, this effect(2dB(A) under 65dB(A) noise) was shown smaller than field test.
