Several general results are derived for diffuse waves in anisotropic solids, including concise expressions for the modal density per unit volume d (ω), and for the participation factor matrix G. The latter is a second-order tensor which describes the orientational distribution of diffuse wave or reverberant energy, and reduces to the identity I under isotropy. Calculations of G for a variety of example materials show significant deviation from I even under moderate levels of anisotropy.
