Abstract

The characteristics of the reflection and refraction of an acoustic wave at its normal incidence to an interface between two multifraction gas suspensions have been studied. We obtain the calculation formulas for the impedance of a multifraction gas suspension, the reflection coefficient, and refraction index. The dependences of the absolute values and arguments of the refraction index and reflection coefficient on the dimensionless frequency are obtained.
