How do our ears show our age? We are all aware of the concept of presbycusis and a plethora of other events that impact our hearing over the passage of time. We are familiar with the standard subjective testing, though from an objective testing point of view, what does this mean? Can our neural degeneration also show with objective testing within audiology? Though relatively small scale (29 participants), this study observed that using a sustained tone stimulation, there was a reduction with age to both the cochlear and brainstem responses. In particular, even with near normal hearing levels, the low frequency following response and the ABR wave I amplitudes showed reduction with age. On the flipside, click-evoked wave V on ABR was not impacted. Saying that, objective testing techniques do not generally have a routine place within adult audiology but one never knows what the future holds.
