We study the propagation of acoustic and elastic waves in random composites consisting of spherical inclusions in a homogeneous elastic host (fluid or solid), using various extensions of the Coherent Potential Approximation (CPA) method, well-known from the electronic problem. We calculate the phase velocity, the scattering mean free path and the transport velocity. The results are compared with experimental data and accurate computational results.
