Wow.
 
That's pretty cool.

I wonder how 'tight' the cone is. That could limit its application to things like home theatre, I mean, it's awesome for an individual, but does it produce enough spread to make it a viable source for a larger group? I wonder too if widening the cone would decrease the volume, or increase to a great extent the amount of energy required to achieve a certain volume.
 
The basic operating principle of HSS uses a property of air known as "non-linearity". A normal sound wave (like someone talking) is a small pressure wave that travels through the air. As the pressure goes up and down, the "non-linear" nature of the air itself causes the sound wave to be changed slightly. If you change a sound wave, new sounds (frequencies) are formed within the wave. Therefore, if we know how the air affects the sound waves, we can predict exactly what new frequencies (sounds) will be added into the sound wave by the air itself. An ultrasonic (beyond the range of human hearing) sound wave can be sent into the air with sufficient volume to cause the air to create these new frequencies. Since we cannot hear the ultrasonic sound, we only hear the new sounds that are formed by the non-linear action of the air.

And if ultrasonic sound waves are produced with no regard to the kinds of new sounds that will be formed due to this sonic disturbance, a bunch of people think that they're hearing ghosts. ;) :D
