’3-D sound’ Unveiled

Iosono, a spinoff company of Germany’s Fraunhofer Institute for Digital Media Technology unveiled a breakthrough in theatrical sound dubbed “3-D sound” at the Society of Motion Picture and Television Engineers’ Technical Conference and Exhibition.

The Hollywood Reporter writes, “The 3-D sound system at the Mann is a ring of 380 speakers, set six inches apart, around the wall of the auditorium.”

The Tech Republic has a 2004 article on “3d Audio” titled “MP3 creator returns with 3D sound”:

…He and his team are touting their new product as true “three dimensional” audio, which can give the impression of, for example, a horse galloping through the center aisle of a movie theater, or pinpoint a noise so that it sounds exactly like a person shouting from outside theater walls. The best existing surround sound speakers can approximate this only for a small “sweet spot,” perhaps a few feet wide, while the Ionsono system would create the same realistic illusion for everyone in the room.
