Abstract
Methods, systems, and computer program products for simulating sound propagation can be operable to define a sound source position within a modeled scene having a given geometry and construct a visibility tree for modeling sound propagation paths within the scene. Using from-region visibility techniques to model sound diffraction and from-point visibility technique to model specular sound reflections within the scene, the size of the visibility tree can be reduced. Using the visibility tree, an impulse response can be generated for the scene, and the impulse response can be used to simulate sound propagation in the scene.
