In room acoustics, the reflection and scattering of sound waves at the boundaries strongly determines the behaviour within the enclosed space itself. Therefore, the accurate simulation of the acoustic characteristics of a boundary is an important part of any room acoustics prediction model, and in particular diffuse reflections at a boundary is one of the most important properties to model correctly for an accurate and perceptually natural result. This paper presents a comparison of two simulation models for the phenomenon of diffuse reflection at a boundary: one based on introducing physical variations at the boundary itself, and another based on the use of a diffusion equation model.
