Numerical simulation and analysis of surface scattering - Part 2

Convention of the European Acoustics Association Forum Acusticum, pp. 857–859

Abstract

Directional scattering patterns of surface contain much more detail information than the single number quantities of scattering and diffusion coefficients.In the development of acoustic computer simulation, more accurate results and natural sound perception of auralization requires more detail information about sound propagation.In this paper, we present an approach for spatial clustering of scattered pattern in dependence on frequency, incidence angles and reflection angles.We also analyze spatial distribution characteristics of reflected energy in different incident angles and the relationship with surface pattern and frequency.Finally, we discuss a more specific evaluation of the directional scattering effect.
