Abstract
Over the very recent years, an alternative model to describe sound fields in enclosures, based on the mathematical theory of diffusion, has been proposed. This model is based on the concept of sound particles traveling along straight lines and striking walls or scattering objects existing in a room. The scope of this work is to present some preliminary investigations in the prediction of objective room-acoustics parameters, such as reverberation time, clarity, and definition through the use of a diffusion equation. This paper will discuss modeling accuracy of the room-acoustics parameters using some numerical examples. Moreover, some issues concerning the numerical implementation by means of finite difference schemes for the diffusion equation are addressed.
