소음지도 작성을 위한 소음예측식의 적합성 평가

To build a basic data for Gwang-ju city noise map framing, road traffic noise measurement results and prediction value when using CRTN, RLS90 XPS31-133 programs were checked with measurement results of traffic noise of restricted area in Gwang-ju city. CRTN, RLS-90, XPS31-133 were used for noise level prediction. The results of this study are followings. When using RLS-90, the difference between prediction value and measured value is 1.1dB(A) whereas using CRTN's case is 2.1dB(A). This result means that these two programs are suitable for prediction of road traffic noise.
