Purpose: The aim of this study was to compose the test for music perception and analyze the characteristic of cochlear implant users’ music perception.Methods: The test was made up with the pitch, melody, and timbre factors, using three low and high frequencies, six music genres, and four types of musical instruments correspondingly. The tests were conducted to 10 normal-hearing (NH) young adults and 10 young cochlear-implant (CI) users.Results: All the music perception tests showed significant differences between NH and CI group [F(1, 4) = 0.018, p = 0.019]. In the pitch test, CI group showed significantly lower correction rate(51.3%) than NH group (82.7%) did with higher correction rates in low frequencies. In the melody test, CI group showed significantly lower correction rate (29.7%) than NH group (95.8%) did with the highest performance in folk songs (51.7%). In the timbre test, CI group showed significantly reduced performance (22.5%) than NH group (65.8%) did. For both CI and NH groups, the pitched percussion showed the highest scores (45% and 100%) while the woodwind showed the lowest scores (13.3% and 48.3%).Conclusion: Out of three tests, CI group showed better performance in pitch perception than melody and timber perception. CI group showed better performances in low pitch sounds, melodies of familiar genre, and sound of pitched percussion instruments’ timber showing complicated music perception ability. To enhance the music perception ability for CI users by aural rehabilitation, more specified and systematic music perception test material should be developed.

The Impact

Purpose A music-related quality of life (MuRQoL) questionnaire was developed for the evaluation of music rehabilitation for adult cochlear implant (CI) users. The present studies were aimed at refinement and validation. Method Twenty-four experts reviewed the MuRQoL items for face validity. A refined version was completed by 147 adult CI users, and psychometric techniques were used for item selection, assessment of reliability, and definition of the factor structure. The same participants completed the Short Form Health Survey for construct validation. MuRQoL responses from 68 CI users were compared with those of a matched group of adults with normal hearing. Results Eighteen items measuring music perception and engagement and 18 items measuring their importance were selected; they grouped together into 2 domains. The final questionnaire has high internal consistency and repeatability. Significant differences between CI users and adults with normal hearing and a correlation between music engagement and quality of life support construct validity. Scores of music perception and engagement and importance for the 18 items can be combined to assess the impact of music on the quality of life. Conclusion The MuRQoL questionnaire is a reliable and valid measure of self-reported music perception, engagement, and their importance for adult CI users with potential to guide music aural rehabilitation.

This paper describes a logatome discrimination test for the assessment of speech perception in cochlear implant users (CI users), based on a multilingual speech database, the Oldenburg Logatome Corpus, which was originally recorded for the comparison of human and automated speech recognition. The logatome discrimination task is based on the presentation of 100 logatome pairs (i.e., nonsense syllables) with balanced representations of alternating “vowel-replacement” and “consonant-replacement” paradigms in order to assess phoneme confusions. Thirteen adult normal hearing listeners and eight adult CI users, including both good and poor performers, were included in the study and completed the test after their speech intelligibility abilities were evaluated with an established sentence test in noise. Furthermore, the discrimination abilities were measured electrophysiologically by recording the mismatch negativity (MMN) as a component of auditory event-related potentials. The results show a clear MMN response only for normal hearing listeners and CI users with good performance, correlating with their logatome discrimination abilities. Higher discrimination scores for vowel-replacement paradigms than for the consonant-replacement paradigms were found. We conclude that the logatome discrimination test is well suited to monitor the speech perception skills of CI users. Due to the large number of available spoken logatome items, the Oldenburg Logatome Corpus appears to provide a useful and powerful basis for further development of speech perception tests for CI users.

Abstract Background Increasing numbers of adults are receiving cochlear implants (CIs) and many achieve high levels of speech perception and improved quality of life. However, a proportion of implant recipients still struggle due to limited speech recognition and/or greater communication demands in their daily lives. For these individuals a program of aural rehabilitation (AR) has the potential to improve outcomes. Purpose The study investigated the effects of a short-term AR intervention on speech recognition, functional communication, and psychosocial outcomes in post lingually deafened adult CI users. Research Design The experimental design was a multisite clinical study with participants randomized to either an AR treatment or active control group. Each group completed 6 weekly 90-minute individual treatment sessions. Assessments were completed pretreatment, 1 week and 2 months post-treatment. Study Sample Twenty-five post lingually deafened adult CI recipients participated. AR group: mean age 66.2 (48–80); nine females, four males; months postactivation 7.7 (3–16); mean years severe to profound deafness 18.4 (2–40). Active control group: mean age 62.8 (47–85); eight females, four males; months postactivation 7.0 (3–13); mean years severe to profound deafness 18.8 (1–55). Intervention The AR protocol consisted of auditory training (words, sentences, speech tracking), and psychosocial counseling (informational and communication strategies). Active control group participants engaged in cognitive stimulation activities (e.g., crosswords, sudoku, etc.). Data Collection and Analysis Repeated measures ANOVA or analysis of variance, MANOVA or multivariate analysis of variance, and planned contrasts were used to compare group performance on the following measures: CasperSent; Hearing Handicap Inventory; Nijmegen Cochlear Implant Questionnaire; Client Oriented Scale of Improvement; Glasgow Benefit Inventory. Results The AR group showed statistically significant improvements on speech recognition performance, psychosocial function, and communication goals with no significant improvement seen in the control group. The two groups were statistically equivalent on all outcome measures at preassessment. The robust improvements for the AR group were maintained at 2 months post-treatment. Conclusion Results of this clinical study provide evidence that a short-term AR intervention protocol can maximize outcomes for adult post lingually deafened CI users. The impact of this brief multidimensional AR intervention to extend CI benefit is compelling, and may serve as a template for best practices with adult CI users.
