Abstract

Following the physical analogy with diffusion of particles in a scattering medium, and assuming sound particles travel along straight lines at sound speed, the room-acoustic diffusion model has emerged as geometrical/statistical room-acoustic prediction tools based on the assumption that the room(s) under consideration contains scattering objects that uniformly scatter the sound particles. In this paper the validity of the room-acoustics diffusion model is investigated using scale-models of a coupled-volume system. This work investigates the valid ranges and limitations of the diffusion model by systematic changes in aperture sizes of coupled-volume systems for comparisons between the acoustical scale-models and the room-acoustic diffusion models. In these physical and numerical models, the sound source and receiver positions relative to the aperture are also investigated.
