Computationally-efficient rendering of diffuse reflections for geometrical acoustics based room simulation

open access: yesActa Acustica
Geometrical acoustics is well suited for real-time room acoustics simulation and is often implemented using the image source model (ISM). One drawback of the ISM is its limitation to specular reflections, while sound scattering plays an important role in
