Abstract

The features of the reflection and refraction of acoustic waves incident at right angles to a layer of a multifractional gas suspension are investigated. Formulas for calculating the reflection and refraction coefficients are obtained. The dependences of the reflection coefficients on the dimensionless frequency for different mass contents of particles and layer thickness are constructed.
