To characterize these functional changes in a clinical population, electrophysiological measures of auditory brainstem and cortical function can be used to index neural markers of aging and ARHL along the auditory pathway. This paper reviews a selection of studies in which electrophysiological techniques from the auditory brainstem response (ABR) to cortical auditory evoked potentials (CAEP) were used to identify key changes in neural processing associated with advancing age and related perceptual deficits. Collectively, these results provide objective evidence for declines in temporal and spectral processing in the auditory periphery and central pathway with increasing age independent of hearing loss. Further research is needed to determine how such evidence-based measures might be altered through different forms of rehabilitative intervention.
