Abstract
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 method for modelling the two-dimensional propagation of sound within an enclosed room is presented which encompasses both of these particular properties by making use of a digital waveguide model
