Improving the Acoustical Performance of Poroelastic Materials 2005-01-2283

The relationship between the acoustical performance and macroscopic material properties of elastic porous materials, based on modified Biot's theory, is used to develop sensitivity relationship among acoustic and macroscopic material properties. The sensitivity information are normalized (scaled) and subsequently used to improve and tune the acoustical performance of elastic porous materials. Example problems are used to demonstrate the applicability of the technique.
