Abstract

It is shown that the incidence angle affects only weakly the character of the frequency dependence of the reflection and transmission coefficients in the frequency range of the “acoustic opacity band” upon transmission of an acoustic signal through a multilayer barrier containing a thin bubble-liquid layer. However, the acoustic-wave incidence under an angle results in the fact that part of the energy is distributed along the barrier and it affects the amplitude of the signal transmitted through the barrier.
