Abstract
To reduce the interior noise in high-speed trains, we have built several interior noise simulation models based on statistical energy analysis and boundary element analysis. By comparing the noise calculated using these models with the measured interior noise in train cars, running through various sections at various speeds, we have confirmed the models is accurate within 1.5 dB for the overall noise level We therefore used them to evaluate contribution factors of the interior panel radiation to the interior noise and to evaluate the effectiveness of several countermeasures. This procedure could be used to design optimal structures for large and quiet passenger cabins.
