Title:
Modeling of Wave Number Dependent Absorptive Characteristics with the Help of the Theory of Porous Media 
Abstract:
The modeling of sound fields in closed volumes is typically done with the help of the Statistical Energy Analysis. In the scope of this theory a diffuse sound field is assumed, resulting in random angles of incidence on the surfaces. If this assumption is violated, a realistic modelling of wave number dependent absorptive characteristics has to be considered. It is possible to describe the absorptive surfaces with their correct wave number depending impedances by modelling the fluid-structu...    »
