I would guess that the effect is related to hearing loss rather than aging, which is called presbycusis, defined as `neural hearing loss due to aging.' There is a natural upward shift of 'pure tone place' in the cochlea with hearing loss, of any type, and this place-shift is therefore correlated to presbycusis.

Some of this literature is keyworded by the term "paracusis." I never heard of this one before. What part of the cochlea shrinks?
