Hmmm.....  Let's see.  It seems to me that sound cancellation, 
especially for a distributed source, must be more complicated than
this discussion suggests.  Isn't it the case that if the source of the
cancelling cound is not coincident with the source of the sound,
cancellation would be perfect only if a few places, not everywhere?

Guess I'd have to ask for a seat in the "No Sounding" section of that
airplane!
