Dear List,
I have always wondered about what drives BM vibrations and decided it 
depends on how one answers the following question.
Do the BM's in a dichotic experiment using two harmonically related 
tones (e.g. 200/300 hz) have the same vibration profile or are they 
different? If different, then one can assume that the stimulus drives 
such vibration, but then it opens up the question of how one perceives 
the fundamental. If the same, it opens up possibilities of a feedback 
process involving higher levels of the auditory system.
I don't know if this is beyond the scope of this forum in which case I 
apologize. However, if this topic is not too crazy, I would welcome any 
answers, guesses or speculations.
Thanking in advance,
Randy Randhawa
