Abstract:
The propensity for degraded auditory perception increases with age. Several studies have shown that while age-related hearing impairment explains a high percentage of the often-reported degradation in auditory perception, there still remain some effects that can only be attributed to the aging process. Even though some classic studies have shown that spectral processing may be immune to age-related degradation, some recent work with broadband measures of spectral processing appears to challenge this notion. This study evaluated the effect of age on narrowband and broadband spectral processing abilities for individuals with mild-to-moderate hearing loss. We controlled for the amount of hearing loss and measured auditory filter bandwidths using notched-noise masking and spectral modulation detection using rippled noise in the same cohort of listeners. Results to date suggest that broadband spectral processing, which uses stimuli that share ecological validity with speech, may be more sensitive to age-related changes in spectral processing compared to narrowband spectral processing.
