MODELING AND DIRECTIONALLY ENCODING THE ACOUSTICS OF A ROOM

Geometrical methods are often used to model the acoustic properties of a room, but are valid only for high frequencies. At low frequencies. diffraction and the effects of room modes cannot be neglected. A metho d for modelling the two-dimensional propagation of sound within an enc losed room is presented which encompasses both of these particular pro perties by making use of a digital waveguide model.
