] SAN DIEGO Rarely is an invention so unique, so
] visceral and so simple that in 15 seconds most people who
] experience it realize it could alter everyday life.
]
] But that's what happens to just about anyone who steps
] out to the back parking lot of American Technology Corp.
] (ATC) here for a demonstration of its invention called
] HyperSonic Sound (HSS).
]
] Essentially, HSS for the first time does for sound what
] the laser did for light %u2014 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.

EXTREME coolness! Coherent audio??? I want!
