Objective: Cochlear implants (CI) have provided tremendous benefit for speech recognition in quiet patients with severe and profound hearing impairment, but implant users still great difficulty perceiving music. The purpose of this study was to develop a test quantify music perception by CI listeners clinically practical manner that could be standardized administration at any center. Study Design: Prospective convenience sample. Setting: Hearing research center an academic hospital. Patients: Eight listeners, including 5 men 3 women experience ranging from 0.5 6 years, participated study. They represented variety devices strategies. Intervention: Administration the Clinical Assessment Music Perception sound field. Main Outcome Measures: assessed using computerized comprising pitch direction discrimination, melody identification, timbre identification. subtest used 2-alternative forced-choice adaptive procedure determine threshold interval discrimination complex change. subtests 12 isochronous melodies 8 musical instruments, respectively. Results: Testing demonstrated broad range perceptual accuracy on all subtests. Test duration averaged less than 45 minutes. Conclusion: is efficient may measure different aspects manner.
