Abstract
The article is a continuation of the work related to the processes of reflection and transmission of sound waves on the boundary of a homogeneous and porous media. The expressions are obtained for determining the coefficients of reflection and passing of an impulse pressure through closed boundary gas saturated porous and homogeneous media. The comparison of the shape of the pulsed signal in the cases of open and closed boundaries of the porous medium. It is shown that appropriate selection of open and closed boundaries, can get a partition with the required acoustic properties.
Keywords: acoustic wave, boundary, coefficients of reflection and passing, porous medium
