Abstract

The interaction of compression waves with a porous layer shielding a rigid wall is investigated. The cases of the presence or absence of the gap between the porous layer and the rigid wall are considered. On the basis of the Fourier method, method of calculation of pressure and stress in the porous layer, the gap and at the obstacle with the passage of the compression waves from the fluid into the porous layer and the subsequent reflection from obstacles, in linear approximation is proposed.
