Re: pitch shift with age

The fact that pitch shift occurs also for virtual pitch/missing fundamental makes the cochlear explanation essentially useless or, at the least, severely incomplete. An alternative explanation proposed (sorry, I don't have the reference at this moment -- maybe someone does?) tied the phenomenon to the well-documented general "slowing down" of nerve activity with age (Birren, J. E. & Fisher, L. M., Annual Review Psychology 46 [1995]).

My own experience with this phenomenon has been pretty dramatic: I once had AP (less than 1% error) and currently misjudge a pitch by as much as a whole tone.
