Directed sound transmission systems and methods using position location

Abstract

Systems and methods herein provide directed sound to venues, including a queue line and locations offering multiple viewing devices with different audio streams. Directed sound can be sent to various locations in the queue line to reach specific individuals, positions in the queue line, etc. A queue rate may be used to determine current locations in the queue line. The directed transmission of sound waves can provide the directed sound through modulation of the sound on an ultrasonic carrier. In connection with directing sound to a specific location in a venue, one or more individuals can be tracked according to an indoor positioning system to send a sound message using a modulated ultrasonic carrier.
