On-beat rhythm and working memory are associated with better speech-in-noise perception for older adults with hearing loss

Even with the use of hearing aids (HAs), speech in noise perception remains challenging for older adults, impacting communication and quality of life outcomes. The association between music perception and speech-in-noise (SIN) outcomes is of interest, as there is evidence that professionally trained musicians are adept listeners in noisy environments. Thus, this study explored the association between music processing, cognitive factors, and the outcome variable of SIN perception, in older adults with hearing loss. Forty-two HA users aged between 57 and 90 years with a symmetrical, moderate-to-moderately severe hearing loss participated in this study. Our findings suggest that on-beat rhythm accuracy, pitch perception, and working memory all positively contribute to SIN perception for older adults with hearing loss. These findings provide key insights into the relationship between music, cognitive factors, and SIN perception, which may inform future interventions, rehabilitation, and the mechanisms that support better SIN perception.
