AAHHH,
so you are "student of Still" and not "still a student"... I like the play on words!
Your guess about phasing makes sense. I did not do much (if any) digital signal processing, but the math I learned suggests exactly that. A very effective noise-cancellation mechanism is made by recording and playing back just out of phase. I believe it is still used (despite practical limitations) in some Mercedes and BMWs. Laboratory demonstrations are just plain astounding: the actual air-pressure waves are stopped!
So the small room, it's not so much that the room is absorbing the sound, nor even that the reed refuses to give any more, it's just that whatever little reverberation there is is enough, and fast enough, to actually silence the extra sound....
Again, I'm not equipped to research this (not in my free time), but if you can find anything to support this (formal or anecdotal), this would be great!
