Influence Analysis of the Parameters on Sound Absorbing Performance for Polymer Wool

Abstract:

This paper, first of all, demonstrates the comparison between simulated results and direct measurements of the absorbing performance of polymer wool. It is found that simulated results are statistically coincided well with experiment results. Secondly, this paper discusses the influence of Biot parameters on the absorbing performance of the polymer wool. Besides, the influencing rules of these factors on the absorbing performance of the polymer wool are analyzed as well. This has great significances to the application of the polymer wool on noise reduction in automobile.
