title: Functional changes in the aging mouse middle ear.
abstract: Laser interferometry was used to measure sound-induced umbo velocity in the aging mouse middle ear. Velocity reductions of as much as 8 dB were seen as the mice aged. These functional differences suggest a variety of structural changes that may occur in the aging middle ear.
