Résumé
In his paper M. A. Biot has shown that the effect of roughness on the reflection of acoustic waves can be obtained by satisfying a suitable boundary condition on a smooth surface. By a method due to H. G. Garnir, we study here the singular and analytic supports of the elementary solution of such a problem in a half space. It leads to a description of the wave front and it turns out that the effect of roughness is the apparition of a supersonic wave phenomenon.
