Modelling Spatial Sound Occlusion and Diffraction Effects Using the Digital Waveguide Mesh
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.
