Abstract: In addition to the room geometry, room acoustic simulations based on geometrical acoustics typically use absorption and scattering coefficients to model the physical behavior of the boundary conditions. The scattering coefficient is often considered to be less relevant, however, in some cases it can also have a substantial impact on parameters such as the reverberation time. If a simulated energy decay is matched to a measured energy decay of a room, it is thus important to adjust absorption coefficients as well as the scattering coefficients. This work reviews and investigates the relationship between the two input parameters and their impact on simulation results, especially on room acoustical parameters.
