REFLECTION OF ACOUSTIC WAVES FROM THE POROUS BARRIER WITH THE "OPEN" BORDER

Process of reflection of linear acoustic waves from a porous barrier with the "open" border is researched. Factors of reflection and passage of a wave are received. Schedules of dependence of the module of factor of reflection from circular frequency are constructed. It is shown, that in the field of low frequencies with reduction of radius of times of environment the module of factor of reflection increases.
