As the improvements of service quality is becoming an important issue the, interior noise level of a train is an important factor of comfortable ride.
To reduce the interior noise level, noise sources of the train need to be removed. However, in case with a structure of large scale and multiple noise sources, an estimation of influences of major noise sources, with indentification of its traveling paths needs to be performed.
In current state, to improve the interior noise reduction, consideration of sound transmission loss of the train body prior to manufacturing is usually performed.
In this study, the sound transmission loss of the train body of new model train of seoul metro"s line no.2 under test opeation is measured and modeling of the train body is performed. And train interior noise is predicted using the measured values.
