Abstract
In this work we report the diffusion of acoustic waves by sonic crystals. We study different configurations of a sonic crystal formed by squared rods in a squared lattice with a finite rigid backing. Several resonances appear related with Fabry-Pérot resonances, the existence of band gaps and the character of diffraction grating of the interface of the crystal.
