The Effects of Music-Based Auditory Training on Hearing-Impaired Older Adults With Mild Cognitive Impairment

Objectives. The present study aimed to determine the effect of music -based auditory training on older adults with hearing loss and decreased cognitive ability, which are common conditions in the older population. Methods. In total, 20 older adults diagnosed with both mild -to -moderately severe hearing loss and mild cognitive impairment (MCI) participated. Half of this group were randomly assigned to the auditory training group (ATG), and the other half were designated as the control group (CG). For the ATG, a 40 -minute training session (10 minutes for singing a song, 15 minutes for playing instruments, and 15 minutes for playing games with music discrimination) was conducted twice a week for 8 weeks (for a total of 16 sessions). To confirm the training effects, all participants were given tests pre- and post -training, and then a follow-up test was administered 2 weeks after the training, using various auditory and cognitive tests and a self -reporting questionnaire. Results. The ATG demonstrated significant improvement in all auditory test scores compared to the CG. Additionally, there was a notable enhancement in cognitive test scores post -training, except for the digit span tests. However, there was no statistically significant difference in the questionnaire scores between the two groups, although the ATG did score higher post -training. Conclusion. The music -based auditory training resulted in a significant improvement in auditory function and a partial enhancement in cognitive ability among elderly patients with hearing loss and MCI. We anticipate that this music -based approach will be adopted for auditory training in clinical settings due to its engaging and easy -to -follow nature.
