철도 환경 소음의 3-D 표현: NIC＠E

3D Expression of Outdoor Railway Noise : NIC＠E

NIC＠E is 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 tile expression method of 3D Graphics for noise level.
