Re: [microsound] Binaural

I was wondering if there is a relation to what Bateson called the moiré effect (two
repetitive patterns create a third pattern in the perceiver)?  Or -- maybe that's
ridiculous, far out or too new agey -- there is this M theory of the cosmos: "In
cosmology there is a  new theory called M Theory or Membrane Theory. It has largely
superceded the old "string theory." The hypothesis with M Theory speculates that the
universe emerged out of two vibrating membranes and, and where the vibrations on the
membranes met created all the particles in the universe as we happen to observe
them." "Re: The universe and the "moire effect"",

To think that the ears also contain two vibrating membranes ...
