Prediction of 3D Outdoor Railway Noise by Using NIC@E

NIC@E를 이용한 철도변 소음의 3차원 예측기법

NIC@E is the software for prediction of various outdoor Noise. The Program is based on the ray tracing technique which has been widely used in an environmental noise prediction and analysis. In this paper, we analyze the Railway noise on the various types of geometrical source conditions in 3D and develope the expression method of 3D Graphics for noise level.
