actually...
the prime number which determined the primitive root diffusor calculation was suggested by Peter DAntonio (my collaborator in the project) was is 138,647, yielding co-primes of 181 & 766. this linear series was folded into 2D by the Chinese Remainder Theorem. there is roughly 47 tons on the walls after milling on a Cosmac horizontal mill, which ran for about 3 months cutting 1532 pieces of 1" MDF. we had thought that "sagging" might be a problem, and worked out a system of installing 1/4" dowels at strategic spots in the array to support it should this be the case - it hasn't been a problem, though.
note in this ETC that the decay is approximately 0.3 seconds, but more importantly, the direct to ambient ratio is in excess of 30dB, which is also the reverberation spec for an anechoic chamber.
the room is hardly anechoic, though. just listening to music in there is extraordinary; ensemble musicians report that it's easier to play live in the room because it's easier to hear in the room.
those that appreciate it use it to it's utmost. the "sound" is more or less like an "acoustic white-out", and the decay is extraordinarily linear with higher frequencies (the Schroeder curves are remarkably linear) having more decay than any other room i've ever experienced. i made the best record i ever made in my life in there (from which that video clip came). unfortunately, Nashville's short-sighted and inept "music" industry will not tolerate innovation of any kind, and i'm told that the room now has heavy curtains hung in front of the diffusors.
i now live in Montreal, by the way.
