Hey,Thatch..wasn't the Dymaxion a concept car in the fifties?
I think what this whole thing is about is that if you can control the acoustics in a given space,your perception of loud,soft,near,far,left,and right,can be completely fooled. A bit of sound being eminated by one of the many transducers in this system is steered and altered by the rest of the transducers in the system. Even with basic phase manipulation you can make a sound seem to be coming from behind your head and nowhere else-while only using a left and right front speaker.
Projecting a whisper over ambient noise is a good example..if you use the system to sample the ambient noise in enough places and enough times,and the system is used to reproduce a sound field that cancels the ambient noise in all the right places,your mind percieves it as silence,and you merely have to add the whisper on top. I know I am oversimplifying it,but I think I'm on the right track.
We recently heard a a new type of system from Eastern Acoustic Works.
It's called a "digitally steerable array" or DSA. It's a pretty traditional column looking speaker,but uses 8 horns stacked one on top of the other and 8 power amps. The pattern is "steered" up or down by as much as 60 degrees. It's intended use is to be flat mounted on a wall,and the "steering" used to focus the sound field down onto the audience. It seems to be done by altering the phase,time and frequency content sent individually to each horn. Small crowd,point it real down to minimize reflections in an empty room. Big crowd,pull it up to cover the back. It's only steerable in one plane now,but as we all know,now is only temporary.....
I think the "outside the box" way of looking at(hearing it?)is to think about creating silence with sound. :scratch2:
