Re: Bite-induced pitch shift?


Thanks for your observations on pitch shift.  I'm curious why a shape
change of the external auditory canal should be implicated.  Does
this effect only apply to broadband signals, such that changing the
canal's resonant frequency might give a "formant" change in the
spectral shape?  I can't see how it could change the pitch of a
pure tone, unless the basilar membrane is also deformed somehow.
