Abstract

Objective: The aim of this study was to investigate the benefits of residual hair cell function for speech and music perception in bimodal pediatric Mandarin-speaking cochlear implant (CI) listeners.

Design: Speech and music performance was measured in 35 Mandarin-speaking pediatric CI users for unilateral (CI-only) and bimodal listening. Mandarin speech perception was measured for vowels, consonants, lexical tones, and sentences in quiet. Music perception was measured for melodic contour identification (MCI).

Results: Combined electric and acoustic hearing significantly improved MCI and Mandarin tone recognition performance, relative to CI-only performance. For MCI, performance was significantly better with bimodal listening for all semitone spacing conditions (p < 0.05 in all cases). For tone recognition, bimodal performance was significantly better only for tone 2 (rising; p < 0.05). There were no significant differences between CI-only and CI + HA for vowel, consonant, or sentence recognition.

Conclusions: The results suggest that combined electric and acoustic hearing can significantly improve perception of music and Mandarin tones in pediatric Mandarin-speaking CI patients. Music and lexical tone perception depends strongly on pitch perception, and the contralateral acoustic hearing coming from residual hair cell function provided pitch cues that are generally not well preserved in electric hearing.

儿童双模人工耳蜗听者残毛细胞功能对语音和音乐感知的益处。

目的:本研究的目的是探讨残毛细胞功能对双语儿童人工耳蜗(CI)听者语音和音乐感知的益处。设计:测量35名说普通话的儿童CI使用者单侧(仅CI)和双峰听力的语音和音乐表现。测试了普通话语音对元音、辅音、词汇语调和安静句子的感知。测量音乐感知的旋律轮廓识别(MCI)。结果:与单纯的MCI相比，电声联合听力显著提高了MCI和普通话语音识别能力。对于MCI，在所有半音间隔条件下，双峰听力的表现都明显更好(p < 0.05)。对于音调识别，双峰表现显著优于音调2(上升;P < 0.05)。单纯CI和CI + HA在元音、辅音和句子识别方面没有显著差异。结论:结果表明，电声联合听力可以显著改善儿童汉语CI患者对音乐和普通话音调的感知。音乐和词汇的音调感知强烈依赖于音高感知，来自残余毛细胞功能的对侧声学听觉提供了通常在电听觉中没有很好保存的音高线索。
