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.

Silent Sound Spread Spectrum (SSSS) is a term that has been associated with various conspiracy theories and fringe beliefs rather than mainstream science or technology. It is often described as a covert technology purportedly used for mind control or psychological manipulation. However, there is little credible evidence to support these claims.
In general, spread spectrum technology refers to techniques used in telecommunications and wireless communications to spread the bandwidth of a signal over a wider frequency range than the original information signal. This can improve signal quality, increase resistance to interference, and enhance privacy and security.
However, the specific term “Silent Sound Spread Spectrum” appears to have originated in conspiracy theories and has been popularized in fringe communities, where it is often linked to allegations of government mind control programs or clandestine efforts to influence human behavior using covert audio signals.
It’s important to approach such claims critically and to rely on credible scientific sources for information. While there are legitimate concerns about privacy and security in the realm of telecommunications and technology, claims about SSSS and mind control typically lack scientific evidence and are more closely associated with conspiracy theories and pseudoscience.
