Well, here it is. The long awaited presentation and website about the wonders of hypersonic sound. While the paper that is linked above will have more extensive explanations about everything, this web page is meant to provide a quick and dirty explanation of how hypersonic sound works.

Well, the system takes an input from a regular input jack where a standard CD player or a simple microphone can be plugged in. The input from the audio source is transformed into a very complex ultrasonic beam by the signal processor. It is then augmented and sent into the air by the emitter, also known as a transducer. Remember that very high frequency waves, which an ultrasonic wave is, are very directional, so a virtual column of sound is formed in front of the emitter. The ultrasonic beam is forcing its way through the air and changing the air into an audible version of the original sound that was converted into the ultrasonic beam. Since the beam is rather tight, and the sound is locked within the tunnel of the beam, the only way the sound can be heard is to stand in front of it or to hear it bounce off of a surface. The sound will not spread in all directions like the typical speaker sound will. In comparison to regular speakers though, if stereo sound is to be simulated, two Hypersonic Sound Systems will be needed, one for each audio channel.

After the neat little black box is put together, you too can hear the hypersonic sound as depicted in the diagram above! The two ways to hear it are to stand in the direct path of the beam, which makes the source of the sound appear as though it were inside your head, and the other way to hear the sound is to hear the sound reflected off of a surface. The ultrasonic wave will his a surface and become a virtual speaker, where the sound appears to originate from to the listeners.
