Sennheiser demonstrated AudioBeam, a new type of ultra-directional loudspeaker intended for applications in museums, exhibitions, theme parks and information terminals at this year’s InfoComm show (June 8 to 11, 2005). AudioBeam generates an ultrasonic signal that demodulates at a short distance in front of the unit, creating a focused listening area.

Sennheiser's AudioBeam uses ultrasound technology that modulates the audible sound onto an ultrasonic carrier frequency via the unit's 150 piezoelectric transducers. The nonlinearity of air means that the signal demodulates a short distance from the transducers, effectively generating a lobe that can be precisely directed and even bounced off reflective surfaces.
