Weaponization of Sound

TED talk with an inventor of silent sound spread spectrum type technology. Sound that doesn’t emanate from the speaker surface but materializes from high-frequency beat patterns in the air along along a LASER-straight, focused beam that does not fade with the inverse square law or suffer air-related distortions. Pinpoint sound destinations. True binaural playback at great distances.

Pinpoint sound destinations. True binaural playback at great distances. Turn up above about 80dB and the air itself begins to distort the sound being transmitted, in fashion of doppler modification.
