Application of Cadna/A software in prediction and assessment of railway noise

Cadna/A(Computer Aided Noise Abatement) is the simulation software based on RLS90 in Germany for calculation, presentation, assessment and prediction of environmental noise.By utilizing the software-program, Cad-na/A designed by Germany Data Kustik Gmbh, the influence of railway traffic noise on environment are simulated and predicted.The measure of controlling environmental noise pollution is also put forward in this paper.
