Abstract
A method for simulating a sound, in which a transient signal generated in a sound source located in an arbitrary position in the virtual space is propagated in a wave motion mode in the virtual space, so that a transient response signal affecting a predetermined observation point is determined, which is characterized in comprising: a plurality of sound ray vectors expressing the transient signal and radiating from the sound source in the virtual space; and a wave potential, which is determined with respect to each of the plurality of sound ray vectors each time each of the sound ray vectors is reflected from a portion of boundaries and further advances, the potential reaching the observation point from the portion of the boundaries defining the virtual space.
