 Abstract
The guideline for railway noise mapping is notificated in the administration law for noise/vibration which is announced by the ministry of environment, Korea. Here input parameters for the railway sound sources are proposed for each prediction models. In case of the application of the vehicle characteristics it is suggested to choose "0(%)" for the disc brake parameter. However new trains have been in revenue service since the announcement of the guideline, an investigation of the effect of the input parameters of the foreign railway prediction models on the prediction results of korean railway systems are needed. In this paper the sound prediction results are analyzed with a focus on the input parameters such as disc brake percentage, rail roughness, rail joints. Schall03 is used for the railway noise prediction which has been using most frequently in Korea. The results are shown and discussed.
