Voice of God Technology? Parametric speakers emit high-frequency ultrasonic waves, beyond human hearing range, modulated with an audible signal. These waves interact with the air, demodulating the signal and creating audible sound waves. The sound is perceived only in the beam’s path, making it appear as if it comes from inside the listener’s head. However, when the listener steps outside the beam, the sound disappears. Parametric speakers manipulate sound wave properties and air’s non-linearity
