Abstract
A visual indicator is incorporated into an ultrasonic emitter/sound system for ultrasonic carrier audio applications. The visual indicator can be utilized to ensure that an orientation of the ultrasonic emitter is appropriate relative to a position of an intended target of the audio modulated ultrasonic carrier signal, or that a listener is appropriately located relative to the ultrasonic emitter such that it can receive a targeted audio transmission.
