目的：本研究的目的是检测人工耳蜗核混合(声+电刺激)人工耳蜗术后患者的音乐感知能力，并与听力正常成人和使用传统长电极设备(Advanced Bionics：90K，Clarion，CIIHF；Cochlear Corporation：CI24M，CI22，Conour；Ineraid)的听力正常成人和CI患者进行比较。将混合CI接受者与NH成人和LE CI接受者在(A)现实世界旋律和(B)乐器的识别方面进行比较。方法和方法：我们测试了4名混合CI接受者、17名NH成年人和39名LE CI接受者对现实世界歌曲的开放集合识别，包括有歌词和没有歌词。我们还测试了14名混合CI接受者、21名NH成人和174名LE CI接受者对演奏7音符短语的8种乐器的闭合集合识别。结果：在识别真实世界的歌曲方面，在没有歌词的条件下，混合CI接受者和NH收听者的准确率都显著高于LE CI接受者(p<；0.0001)，后者只需要依赖音乐提示。在低频和高频范围的乐器识别上，LE组的准确率明显低于混合组或NH组(p<；0.0001)。结论：这些结果虽然是初步的，但表明低频听觉的保存对于真实世界音乐刺激的感知是重要的。
AIM: The aims of this study were to examine the music perception abilities of Cochlear Nucleus Hybrid (acoustic plus electric stimulation) cochlear implant (CI) recipients and to compare their performance with that of normal-hearing (NH) adults and CI recipients using conventional long-electrode (LE) devices (Advanced Bionics: 90K, Clarion, CIIHF; Cochlear Corporation: CI24M, CI22, Contour; Ineraid). Hybrid CI recipients were compared with NH adults and LE CI recipients on recognition of (a) real-world melodies and (b) musical instruments.PATIENTS AND METHODS: We tested 4 Hybrid CI recipients, 17 NH adults, and 39 LE CI recipients on open-set recognition of real-world songs presented with and without lyrics. We also tested 14 Hybrid CI recipients, 21 NH adults, and 174 LE CI recipients on closed-set recognition of 8 musical instruments playing a 7-note phrase.RESULTS: On recognition of real-world songs, both the Hybrid recipients and NH listeners were significantly more accurate (p < 0.0001) than the LE CI recipients in the no lyrics condition, which required reliance on musical cues only. The LE group was significantly less accurate than either the Hybrid or NH group (p < 0.0001) on instrument recognition for low and high frequency ranges.CONCLUSIONS: These results, while preliminary in nature, suggest that preservation of low-frequency acoustic hearing is important for perception of real-world musical stimuli.
