Patent ID: 8515105

Claim:
A method of sound simulation for generating an actual sound that simulates a fictitious sound that is perceived to be emanating from a perceived sound source at a first location within a first region, wherein the actual sound is to be sensed by a listener at a second location different from the perceived sound source at the first location, the method comprising: providing for sound simulation a third region surrounded by a virtual external boundary that forms a space outside of and encloses (1) the first region surrounded by a first boundary to which at least a first speaker is proximately positioned to produce the actual sound and (2) a second region surrounded by a second boundary, the second region in a space located within the first region, wherein the perceived sound source at the first location is positioned outside the second region while still being positioned inside the first region, and the second location where the listener is located to experience the sound simulation is positioned inside the second region; calculating at least one adjustment value based upon a position of the first location, a position of a fictitious speaker positioned proximate the second boundary of the second region, a position of the virtual external boundary, and a position of the center of the second region to include sound effects of sound traveling from the fictitious sound being generated by the perceived sound source to the virtual external boundary and bouncing back from the virtual external boundary to locations including the fictitious speaker, wherein the sound traveling includes sound paths that pass through the second region and sound paths that do not pass through the second region, and the included sound effects include an attenuation or a time delay based on a traveling distance of the fictitious sound with respect to the second boundary and the center of the second region; and generating a modified sound at the first speaker positioned proximate the first boundary of the first region, the modified sound being determined from the fictitious sound at least in part based upon using the at least one adjustment value, wherein the generating of the modified sound at the first speaker results in the perception of a sound being generated at the first location.
