Abstract
In establishing silent environment such as automobile and industrial instrument, the roles of the insulating materials are critical. The proper and effective positioning of insulating materials is essential in the field of noise as well as in designing silent automobile. In this paper, we proposed the systematic and efficient scheme for optimizing complete automotive interiors for noise control. In order to attain this purpose, following analysis has been carried out: First, measuring the Biot parameters of insulating materials and the transmission loss with reflecting the appropriate arrangement of insulating materials has been experimented. In addition, we made comparison among transmission loss by the tools of analysis and verification, experimental value under consideration of various situations of automobile and analysis by the SEA.
