I suspect audio applications of crystals has not been peer reviewed. Any more than Mpingo discs, Schumann frequency generators, Shakti Stones, the Tice Clock, holographic foil, WA Quantum Chips, tiny bowl acoustic resonators, coloring CDs, and a bunch of other things have been peer reviewed. I suspect two reasons crystals haven't been peer reviewed are the science community is unaware of this application of crystals AND if they are aware of it they might be just a tiny bit apprehensive about tacking such a subject, if you know what I mean. If you think some organization such as AES is going to run out and sign up to look into crystals any time soon, I wouldn't hold my breath.
