本研究的目的是检验人工耳蜗 (CI) 用户的音乐感知与其词汇音调感知相关的假设，并且这两种类型的感知在电听觉中具有相似的机制。对一组 CI 用户和一组正常听力 (NH) 的听众进行了词汇音调感知测试和音高间隔辨别测试。 19 名成年 CI 用户和 10 名以普通话为母语的 NH 听众参与了这项研究。 CI 组的音调感知表现平均正确率为 58.3%（正确率±19.78%），而 NH 组的表现接近完美。 CI 组的音高辨别平均阈值为 5.66 半音（± 5.57 半音），而 NH 组的阈值为 0.44 半音。 CI 用户的音调感知表现与其音高辨别阈值之间存在很强的相关性（r=-0.75，p<0.001）。音乐和词汇音高感知彼此密切相关，并且它们在电听觉中可能具有相似的机制。
The purpose of the present study was to test the hypothesis that cochlear implant (CI) users’ music perception is correlated with their lexical tone perception and the two types of perception share similar mechanisms in electric hearing. A lexical tone perception test and a pitch interval discrimination test were administered to a group of CI users and a group of normal-hearing (NH) listeners. Nineteen adult CI users and 10 NH listeners who are native-Mandarin-Chinese speakers participated in the study. Tone-perception performance of the CI group was, on average, 58.3% correct (± 19.78% correct), and performance of the NH group was near perfect. The CI group had a mean threshold of 5.66 semitones (± 5.57 semitones) in pitch discrimination as compared to the threshold of 0.44 semitone from the NH group. There was a strong correlation between the CI users’ tone-perception performance and their pitch discrimination threshold (r=−0.75, p<0.001). Musical and lexical pitch perception is strongly correlated with each other and they might share similar mechanisms in electric hearing.
