Directional Sound

The system focuses sound on a specific area and transmits sound information to a small area.

From sketch

The applications for Directional Sound are varied! The system is suitable for dividing sound zones in a car, as sound equipment for exhibitions, showrooms and billboards. The sound is transmitted in one direction, while the overall silence is maintained in the room. The device uses modulated ultrasound technology. The Directional Sound focuses and transmits audio information to a small area. Two speakers emit sound waves in the range of 40 to 80 kHz. A nonlinear medium acts as a demodulator. As the waves propagate in the air, pulses of audible frequencies appear in the ultrasound. Thus, the human-audible sound is generated directly in the air!
