Digital waveguide mesh structures can be used as an alternative to geometrical acoustics when modelling the spatial and reverberant properties of a space. Wave propagation effects such as diffraction and interference are an inherent feature in these models, enabling sound occlusion and diffraction to be simulated. This results in a more accurate room impulse response measurement, particularly at low frequencies where these effects are especially noticeable.
