HSS: now you'll really have to get a good position

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.

More about this at http://www.wirelessnewsfactor.com/perl/story/21621.html.

However, the paragraph that most caught my attention was this:

The company is also beginning to market a couple of other sound technologies, including one called High Intensity Directed Acoustic (HIDA), which can generate sound waves so intense that they can instantly incapacitate a human. The military is interested.

Strange. Didn't they know that we already have such technology?
