Distortion product otoacoustic emissions in young adult and geriatric cats.

•Distortion product otoacoustic emissions (DPOAE) are thought to reflect an amplifier function of cochlear outer hair cells.•DPOAEs in geriatric and young adult cats were compared to determine frequency-specific age-related changes in responses.•No differences in DPOAE amplitudes were observed in geriatric cats compared to control cats.•There was no correlation between DPOAE amplitude and age of cat.•Age-related hearing loss (presbycusis) may be delayed or absent in cats compared to dogs and human beings.
