Abstract

The method to reduce interior noise of train was being studied. To improve transmission loss of train is one of the best way to reduce interior noise. But, the estimate to transmission loss requires lots of the commercial costs. In this study, the method to estimate transmission loss of high speed train is proposed using a scale reverberation chamber. The result shows that a transmission loss estimated using small scale reverberation is similar to that using huge reverberation chamber. The transmission loss estimated based on small scale reverberation chamber can be optimal with respect to the commercial coasts.
