Coefficients of reflection and transmission of acoustic waves as a function of the velocity of the reflecting surface

Annotations languages:

The problem of reflection and refraction of a plane acoustic wave on the surface of a solid body moving in a fluid solved. To obtain expressions for reflection and transmission coefficients as functions of the characteristics of the initial wave, adjacent media and the speed of the solid. Found that the reflection and transmission coefficients depend not only on the angle of incidence and characteristics of the media, but also the frequency of the incident wave and the speed of the body.
Keywords: acoustic waves, reflection, refraction and reflection angles, the frequency of the reflected and refracted waves, reflection and transmission coefficients
