A method for representing acoustic scattering in the Spherical Harmonic domain is applied to simulated responses of a non-diffusive and a diffusive geometry. Established metrics are applied in order to evaluate the performance of these geometries and their effects are traced to the Spherical Harmonic domain. The analysis of the scattering geometry indicate that symmetry in the acoustic field increases the sparsity of the matrix. Diffusive behaviours indicate a spreading of the energy between incident and outgoing scattering modes. These non-sparse structures could be synthesized for producing virtual acoustic diffusers.
