ABSTRACT:
There is disclosed an omnipresent sound system for use by a listener in an artificial reality system which operates to couple sound with the presented objects such that as the sound moves with respect to the user, the user will have the perception of the changing sound both in pitch and in volume. The sound system is comprised of a series of piezoelectric elements spaced apart around a user's head. The system is designed to program each element individually so as to create the illusion of omnipresent three-dimensional sound in conjunction with images presented to the listener, which images define an artificial environment.
