    Ahem.  As a tuba player and one interested in acoustics and psychoacoustics, i think that whoever wrote the article that Andy's referring to either is joking or is an idiot.
    To get 57 octaves below middle C (which is what, 256 cyles per second) you would have to divide 256 by 2 successively 57 times.  My calculations (which admittedly could be wrong) show that this would be a 'frequency' of 0.00000000000000710542735760, or one 'sound' impulse every 140737488355328 seconds, which works out to be a vibration-beat every 8,925,512.96 years.
    That's a very low blow indeed.
