Abstract

See full text

Methods and systems for estimating diffraction effects during sound propagation in a scene, which include generating, for each distance value from distance values, a subpath between a first point of the scene and a second point of the scene passing through a third point of the scene which is at a distance from a path between the first point and the second point equal to the distance value. Furthermore, for each generated subpath, a transmission value related to a degree of occlusion of the subpath by objects in the scene is determined. Also, a diffraction amplitude response is determined using a first transmission value determined for a first subpath generated for a first distance value from the distance values and a second transmission value determined for a second subpath generated for a second distance value from the distance values.
