Abstract
In order to reduce the interior noise in high-speed trains, we have developed a prediction model of interior noise distribution based on statistical energy analysis (SEA) and boundary element analysis (BEA). Experimental results using real cars running at various velocities are used to construct Hybrid SEA model. The developed model can predict internal overall noise within 1.5 dB. A BEA model is also developed to calculate interior noise distribution, which agrees well with the measurement results. These calculation models can be used to find out optimum solutions to reduce interior noise of high-speed trains.
