Evaluation Method of the Transmission Loss for Railway Vehicle Structures.

철도차량 구조물의 TL 시험 평가 기법

In order to evaluate the sound transmission loss of a structure, a large reverberation room described by ISO is generally used. ISO test method is however for architectural structures, which is not properly implemented for small mechanical structures, such as rolling stocks. In this paper, evaluation procedure for railway vehicle structures has been proposed.
