HyperSonic Sound technology – an invention of the American Technology Corp is now available on the market. I remember first reading about it in about 2003, and decided to check it out today. Here’s what they say

“Similar to a beam of light, HSS uses ultrasonic energy to ‘shine’ your sound on a very specific area.  HSS converts music or voice into a complex ultrasonic signal prior to amplification. Once emitted, the converted sound forms a sound column in front of the emitter, which remains focused as it encounters a listener located in the narrow column of sound.”
