High Speed Rail : Prediction of Aerodynamic Noise

고속철도소음예측 : 공력소음의 속도민감성

Noise pollution from a high speed train has been a serious social issue nowadays. Especially when a train speed exceeds 300km/hr, an aerodynamic noise level has been known to be increased based on 4-6th power laws. In this paper, a simple approach to evaluate the sensitivity effect on noise due to the speed change has been examination.
