Abstract

Because the refracted sound field of a finite beam extremely depends on the size and on the frequency of the generating element, Snell's law in many cases is not applicable to calculate the refraction angle of a finite beam. Approaches using plane reflection and transmission coefficients in connection with a discretization of the source into elementary point sources are more exact. This paper demonstrates that the application of plane reflectionand transmission coefficients requires a point to point distance smaller than a half wavelength in order to obtain an accurate sound field of the refracted beam.
