A system for generating at least one remote virtual speaker location in connection with at least a partial reflective environment in combination with an audio speaker for creating multiple sound effects including a virtual sound source from the reflective environment which is perceived by a listener as an original sound source, by generating a primary direct audio output by emitting audio compression waves toward a listener, and generating a secondary indirect audio output from at least one virtual speaker remote from the audio speakers, by emitting ultrasonic sound from at least one parametric speaker associated with the audio speakers and oriented toward at least one reflective environment which is remote from the audio speakers, thereby indirectly generating sound from a reflective environment which is perceived as a virtual speaker, and synchronizing the primary audio output of the audio speakers with a secondary audio output from the at least one virtual speaker such that the listener hears a plurality of sound effects from a plurality of directions.
A method for generating at least one remote virtual speaker location in connection with at least a partial reflective environment and in combination with an audio speaker for creating a plurality of sound effects including a virtual sound source from the reflective environment which is perceived by a listener as an original sound source, said method comprising the steps of:
A method for providing reinforced propagated sound from a virtual Speaker at a separate location from a sound source which originates the propagated sound, said method comprising the steps of:
A parametric sound system for providing multiple speaker locations around a listener with respect to a sound source location, said sound system including at least one parametric speaker having audio output generated in air from ultrasonic frequencies and being oriented toward at least one reflective surface which is remote from the sound source, said at least one parametric speaker providing secondary audio output along a path of reflective, parametric propagation for developing at least one virtual speaker remote from and electronically unconnected with the sound source.
A method for distracting a person's attention toward a remote location, by indirectly generating generally omni-directional sound at a remote virtual speaker source distant from the person, said generally omni-directional sound comprising at least one new sonic or subsonic frequency which corresponds to a difference between at least two interacting frequencies as part of a parametric speaker, said method comprising the steps of:
A method for directing audio sound toward a location which is remote from an individual's location and concealed around a corner of a physical structure by indirectly generating omni-directional sound at a remote virtual speaker source distant from the individual but along a common reflection surface, said omni-directional sound comprising at least one new sonic or subsonic frequency which corresponds to a difference between at least two interacting ultrasonic frequencies as part of a parametric speaker, said method comprising the steps of:
