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, Sci-enceDirect, 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 metaanalysis showed standardized mean difference as a measure of the effect size, in musical improvement between the preand 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.
Tinnitus refers to the perception of ringing sounds in the ear that are not heard by others. Counseling plays a vital role in tinnitus intervention. Counseling provides correct information about tinnitus and hearing loss, corrects any misunderstandings related to tinnitus, and suggests precise alternative interventions for tinnitus. In this review, we aimed to examine the counseling contents in Tinnitus Retraining Therapy (TRT), Cognitive Behavioral Therapy (CBT), and Tinnitus Activities Treatment (TAT) to identify information that could be useful for counseling approaches and contents for the various tinnitus intervention methods. We searched Web of Science, Embase, Science Direct, and PubMed for relevant articles. Of the 5,283 articles, 31 were included in the final review of counseling contents for TRT, CBT, and TAT. Based on our findings, we were able to summarize the main contents of counseling in TRT, CBT, and TAT. Although the contents of counseling may vary depending on the individuals with tinnitus, our review provided information that may help audiologists or hearing professionals further understand the fundamentals of counseling for each tinnitus intervention. Our review may serve as a guideline for tinnitus counseling according to tinnitus interventions.
<b><i>Background:</i></b> Although many clinicians have attempted music training for the hearing-impaired children, no specific effects have yet been reported for individual music components. This paper seeks to discover specific music components that help in improving speech perception of children with cochlear implants (CI) and to identify the effective training periods and methods needed for each component. <b><i>Method:</i></b> While assessing 5 electronic databases, that is, ScienceDirect, Scopus, PubMed, CINAHL, and Web of Science, 1,638 articles were found initially. After the screening and eligibility assessment stage based on the Participants, Intervention, Comparisons, Outcome, and Study Design (PICOS) inclusion criteria, 18 of 1,449 articles were chosen. <b><i>Results:</i></b> A total of 18 studies and 14 studies (209 participants) were analyzed using a systematic review and meta-analysis, respectively. No publication bias was detected based on an Egger’s regression result even though the funnel plot was asymmetrical. The results of the meta-analysis revealed that the largest improvement was seen for rhythm perception, followed by the perception of pitch and harmony and smallest for timbre perception after the music training. The duration of training affected the rhythm, pitch, and harmony perception but not the timbre. Interestingly, musical activities, such as singing, produced the biggest effect size, implying that children with CI obtained the greatest benefits of music training by singing, followed by playing an instrument and achieved the smallest effect by only listening to musical stimuli. Significant improvement in pitch perception helped with the enhancement of prosody perception. <b><i>Conclusion:</i></b> Music training can improve the music perception of children with CI and enhance their speech prosody. Long training duration was shown to provide the largest training effect of the children’s perception improvement. The children with CI learned rhythm and pitch better than they did with harmony and timbre. These results support the finding of past studies that with music training, both rhythm and pitch perception can be improved, and it also helps in the development of prosody perception.
Background and Objectives: The present study aimed to explore meaningful change in the musical performance of cochlear implant (CI) users according to age after receiving music training compared to the other CI users who did not receive any music training and normal hearing (NH) listeners.Materials and Methods: Article search was conducted from five journal databases. In accordance with PICOS criteria, 29 articles and 15 articles were included for the CI and NH groups, respectively. A total of 44 articles consisting of 407 CI users and 486 NH participants were then analyzed. Using the data gathered from pre- and post-training, meta-analysis was applied by the random-effects model, and then piecewise meta-regression was employed.Results: CI users with music training showed better performance than those without the training across all ages. The curve change in musical performance when training showed that the CI users was similar to the general pattern of NH performance, indicating that the CI users gained benefits from music training and developed perceptual ability, even though it was not as high as the level of NH counterparts.Conclusions: This finding supports the benefits of active engagement with music for both CI users and NH listeners, while noting the important role of music as one of the primary aural rehabilitation approaches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
