Abstract: The paper presents the results of a study of the evolution of a wave signal when reflected from a rigid wall with a vapor-gas bubble “curtain” located in front of it in a liquid, which takes into account the heat and mass transfer on the interphase surface in the acoustic approximation. Based on the numerical calculations, using the fast Fourier transform method, wave patterns for the evolution of pressure pulses are obtained and the influence of various parameters of the state of a liquid with vapor-gas bubbles on the reflection and passage of acoustic waves through the curtain in front of the solid wall is analyzed.
