Essentially, HSS for the first time does for sound what the laser did for light — intensely focuses and channels it so it can travel great distances without dispersing. In the demo, a technician points a speaker the size of a cereal box at someone standing 100 yards away. Amid the din of the nearby freeway, the technician plays a recording of ice cubes clinking into a glass.

To the listener, the sound comes across as if it were through headphones, totally unlike a sound blaring from a distant speaker over oppressive car noise. Take two steps to the side, out of the sound beam, and you hear nothing at all. Step back in, and there it is again.

Looks like it's a copy of the Audio Spotlight, which has been on the market for a few years, and is installed in lots of major museums and public areas. I'm sure you can find them in public to hear them yourself.
