Abstract

Sound absorption can be modelled as a surface boundary condition by means of the impedance elements in B2000 or as a volume by means of the Limp elements. Both methods are simplifications of a porous material. The Biot theory allows a more complete description of the sound absorbing material and models the acousto-elastic interaction of the elastic frame (skeleton) and the fluid inside. This theory is implemented in B2000 and the first results are presented. A short overview of the experimental sound reduction techniques at the laboratory is presented as well.
