A finite amplitude ultrasound wave that can be amplitude modulated by any audio signal is radiated from a transducer array into air as the primary wave. As a result, an audio signal is produced in the air because of the self‐demodulation effect of the AM sound wave due to the nonlinearity of the air.

Audio spotlighting exploits the property of non-linearity of air. When inaudible ultrasound pulses are fired into the air, it spontaneously converts the inaudible ultrasound into audible sound tones, hence proved that as with water, sound propagation in air is just as non-linear, and can be calculated mathematically.

audio spotlighting emitter 9. Modulated signal travels through the air. Due to the nonlinearity property of air new sounds are formed within the wave. The new frequencies will be added into the sound wave by the air itself. frequency in the range of 20 Hz to 20 KHz . Since we cannot hear the ultrasonic sound, we only hear the new sounds that ...

Audio spotlighting is really going to make a revolution in sound transmission and the user can decide the path in which audio signal should propagate. Due to the unidirectional propagation it finds application in large number of fields. Audio spotlighting system is going to shape the future of sound and will serve our ears with magical experience.
