Although the cochlear implant (CI) is successful for understanding speech in patients with severe to profound hearing loss, listening to music is a challenging task to most CI listeners. The purpose of this study was to assess music perception ability and to provide clinically useful information regarding CI rehabilitation.
Ten normal hearing and ten CI listeners with implant experience, ranging 2 to 6 years, participated in the subtests of pitch, rhythm, melody, and instrument. A synthesized piano tone was used as musical stimuli. Participants were asked to discriminate two different tones during the pitch subtest. The rhythm subtest was constructed with sets of five, six, and seven intervals. The melody & instrument subtests assessed recognition of eight familiar melodies and five musical instruments from a closed set, respectively.
CI listeners performed significantly poorer than normal hearing listeners in pitch, melody, and instrument identification tasks. No significant differences were observed in rhythm recognition between groups. Correlations were not found between music perception ability and word recognition scores.
The results are consistent with previous studies that have shown that pitch, melody, and instrument identifications are difficult to identify for CI users. Our results can provide fundamental information concerning the development of CI rehabilitation tools.
尽管人工耳蜗(CI)在重度至极重度听力损失患者理解言语方面取得了成功,但对于大多数 CI 使用者来说,听音乐仍是一项具有挑战性的任务。本研究旨在评估音乐感知能力,并为 CI 康复提供具有临床意义的信息。
10 名正常听力者和 10 名具有 2 至 6 年植入经验的 CI 使用者参与了音高、节奏、旋律和乐器的分测验。使用合成钢琴音作为音乐刺激。在音高分测验中,参与者被要求辨别两个不同的音高。节奏分测验由五、六和七个间隔的五组组成。旋律和乐器分测验分别评估了对八个熟悉旋律和五个乐器的识别,这两个分测验均采用封闭集的方式进行。
CI 使用者在音高、旋律和乐器识别任务中的表现明显逊于正常听力者。两组在节奏识别方面没有观察到显著差异。音乐感知能力与单词识别分数之间未发现相关性。
这些结果与先前的研究一致,表明 CI 用户难以识别音高、旋律和乐器。我们的结果可以为 CI 康复工具的开发提供基本信息。
