The Future of Sound

Evan Schwartz has written about the battle shaping up between two competing technologies that both employ directional sound, in an article(1) for Technology Review. This new type of audio delivery is able to beam sound into a narrow path, and eventually it is envisioned that a family of four "could be sitting in a car enjoying four different musical selections or radio broadcasts-with no headphones," he writes.
Inventor Elwood "Woody" Norris has created the Hypersonic Sound system for American Technology Corporation(2), while entrepreneur F. Joseph Pompei has introduced his acoustical product via Holosonic Research Labs(3). Both hope their systems will in time replace traditional loudspeakers.
