中文摘要：

目的评价成人人工耳蜗植入者对音乐旋律及音色的感知能力。方法对13例人工耳蜗植入者（男8例，女5例，平均年龄26．5±6．9岁）分别进行音乐聆听行为评估和旋律辨别、乐器辨别测试。实验使用慕尼黑音乐经验问卷MUMU（Munich music questionnaire）和人工耳蜗音乐评估软件Mu．S．I．C（musical sounds in cochlear implant）进行评估。对照组为40例听力正常受试者（男21例，女19例，平均年龄26．8±6．7岁）。结果①人工耳蜗组与听力正常组的年龄及音乐经验相互匹配。②人工耳蜗组旋律辨别平均正确率为69．3％，乐器辨别平均正确率为51．2％，听力正常组旋律辨别平均正确率为80．4％，乐器辨别平均正确率为85．3％。两组比较，差异存在统计学意义（P=0．000）。结论成人人工耳蜗植入者的旋律感知能力和音色感知能力明显落后于听力正常者。

英文摘要：

Objective To assess the music melody and timbre perception abilities of adults with cochlear implants. Methods Thirteen adult cochlear implant recipients and forty normal-hearing adults participated in this study. Munich music questionnaire（MUMU） and musical sounds in cochlear implant（Mu.S.I.C） were used to assess the music experience, melody and timbre perception for both normal-hearing adults and adult cochlear implant recipients. Results The age and music experience of normal-hearing subjects and cochlear implant subjects matched each other. The average scores of melody discrimination and instrument identification test for cochlear implant recipients were 69.3% and 51.2%,respectively.The average scores of melody discrimination and instrument identification for normalhearing participants were 80.4% and 85.3%, respectively. The differences between the two groups were significant （P=0.000）. Conclusion The adult cochlear implant recipients perform significantly poorer in melody and timbre perception in comparison with normal-hearing listeners.
