Numerous behavioural studies support the hypothesis that there are age-related auditory temporal processing deficits. The effects of age on some psychoacoustic and speech tasks implicate a loss of synchrony or periodicity coding, while other results point to losses in gap and duration coding, or poor use of envelope cues. Performance on psychoacoustic tests of auditory temporal processing has been related to performance on speech tests. This paper reviews the evidence for age-related differences in performance to address two questions: Does aging affect auditory temporal processing at one or more levels, and how are these age-related differences related to the processing of speech? Future directions for research are proposed to address the extent to which different types of auditory temporal processing deficits are inter-related. Future directions for practice are proposed to address the need to develop a new approach to the assessment and rehabilitation of sub-types of presbycusis. Differentiating neural presbycusis from other sub-types may clarify the bases of individual differences in temporal processing and their consequences to speech understanding.
