ear buzz update

[Mark Purney]

Such a device would only work if we had a way for it to "hear" the 
tinnitus noise exactly as you are hearing it. This would be the only way 
to produce a cancellation signal that is perfectly matched in frequency, 
but out of phase with, the original noise. Otherwise, you would get 
phasing or beats, and/or end up doubling the noise.
