A study on the Interior Noise Reduction of Model Car Using the Structural-Acoustic Sensitivity Analysis
구조-음향 연성계의 민감도해석을 이용한 모형차량의 소음저감에 관한 연구
Abstract
The object of this study is the numerical analysis about the sound pressure distribution in reverberation rooms. In order to obtain the effect of the boundary conditions of the wall, the sound field was computed for various absorption coefficients and impedances. And the effect of the room shape was investigated by dealing with pentagonal type as well as the rectangular type. In addition an experiment was performed for the sound pressure distribution in a reverberation room and the result was compared with the analysis.
