Three-dimensional idealized unit-cell based method for computing acoustic properties of low-density reticulated foams

Abstract : This paper presents recent developments in the field of micro-acoustics of porous media. The fundamental idea of the proposed approach is that it is possible to assess porous microstructure and acoustical properties from the three-dimensional implementation of micro-acoustics based scaling relations on porous materials. We illustrate this approach through results from the application of this technique to real samples of predominately open-cell polymeric foams.
