Auditory music training improves musical perception among hearing-impaired listeners, with greater effects in children and longer training periods being necessary for significant improvement. Cochlear implant users show better effects compared to bi-modal users, while the difference in training effects between users with and without previous musical experience is nonsignificant.
This study aimed to evaluate the efficacy of music training on the improvement of musical perception among hearing-impaired listeners using a systematic review and meta-analysis. Article search was conducted from five databases, Scopus, ScienceDirect, Web of Knowledge, CINAHL, and PubMed. A total of 186 participants from 10 studies investigating the music training effects on individuals fitted with hearing assistive devices and outcome measurements were included. The meta-analysis showed standardized mean difference as a measure of the effect size, in musical improvement between the pre-and post-training. Although the funnel plot yielded an asymmetrical graph, the Egger's regression showed no significant publication bias. Interestingly, subgroup analysis showed that the training effect was greater in children than in adults. With a necessity of longer training period to significantly improve their musical perception, cochlear implant only users had better effect compared to bi-modal users with both cochlear implant and hearing aids. However, the difference in the training effect between the users with and without previous musical experience was nonsignificant. The present study concludes that auditory music training brings hearing-impaired listeners into better musical perception while informing that training effects differ depending on age, duration of the training, and the type of hearing device used.
