Objective
Evaluate the conceptual framework that age effects on the electrophysiological binaural masking level difference (MLD) are partially mediated by age-related hearing loss and/or global cognitive function via mediation analysis. Design Participants underwent a series of audiometric tests. The MLD was measured via cortical auditory evoked potentials using a speech stimulus (/ɑ/) in speech-weighted background noise. We used mediation analyses to determine the total effect, natural direct effects, and natural indirect effects, which are displayed as regression coefficients ([95% CI]; p value). Study sample Twenty-eight individuals aged 1987 years (mean [SD]: 53.3 [25.2]), recruited from the community. Results Older age had a significant total effect on the MLD (-0.69 [95% CI: −0.96, −0.45]; p Conclusions The electrophysiological MLD may be an age-sensitive measure of binaural temporal processing that is minimally affected by age-related hearing loss and global cognitive function. |
