Computational Analysis of Sound Transmission of Insulating Materials Using FEM
전산 해석에 의한 차음재의 투과손실 예측
Abstract
The importance of insulating material becomes greater recently in order to attain a quieter life style amidst today's sound noise such as transportation, industrial machinery. The demand for insulating material is increasing due to the increase of noise space. It is reasonable to predict the transmission loss and the absorption of the insulating Material before arranging it in the appropriate places and attaining a Pleasant acoustic environment inside the space. The experiments of insulating material's were performed using Impedance tube Type 4206 T of B&K, and VIOLINS which is a FEM Program of LMS was used for the analysis
