In this paper the development of a two‐dimensional elastic‐absorption finite element model of isotropic elastic porous noise control materials is described. A method for coupling elastic‐absorption finite elements with conventional acoustic finite elements is also presented for the cases when the interface between the adjacent air space and the foam is either unfaced or sealed by a membrane. The accuracy of the acoustic/elastic‐absorption model has been verified by comparing its predictions… CONTINUE READING
