摘要
背景和目的：词汇音对人工耳蜗（CI）使用者来说是一项挑战，尤其是在噪音条件下。双模态听力利用对侧的残余听力，可为噪声中的音调识别带来益处。本研究旨在评估使用单侧人工耳蜗或双模听力的语前聋普通话儿童在稳态噪声和多语者咿呀声中的音调识别能力：53名接受了CI的舌聋儿童参加了这项研究。其中 22 名是单侧 CI 使用者，31 名在对侧耳佩戴助听器（即双模听力）。所有受试者都在安静环境和两种掩蔽物（语谱噪声（SSN）和双语咿呀声（TTB））中接受了普通话音调识别测试，信噪比分别为 -6、0、+6 和 +12dB：虽然两组在安静环境下的音调识别能力没有差异，但在噪音条件下，双模态组的表现优于单侧 CI 组。在 SSN 条件下，信噪比为 0、+6 和 +12 dB 时，两组之间的差异显著（均为 p 0.05）。在所有测试的信噪比条件下，TTB 对单侧 CI 组和双模组的音调识别产生的掩蔽效应均大于 SSN（所有 p 均为 0.05）：带 CI 的舌前失聪儿童在嘈杂环境中的音调感知能力面临挑战，尤其是当噪音振幅波动较大时，如多语种咿呀学语。在残余听力允许的情况下，在对侧佩戴助听器有利于在噪声中识别音调。
Lexical tone recognition in multi-talker babbles and steady-state noise by Mandarin-speaking children with unilateral cochlear implants or bimodal hearing
Background and objectives
Lexical tone presents challenges to cochlear implant (CI) users especially in noise conditions. Bimodal hearing utilizes residual acoustic hearing in the contralateral side and may offer benefits for tone recognition in noise. The purpose of the present study was to evaluate tone recognition in both steady-state noise and multi-talker babbles by the prelingually-deafened, Mandarin-speaking children with unilateral CIs or bimodal hearing.
Methods
Fifty-three prelingually-deafened, Mandarin-speaking children who received CIs participated in this study. Twenty-two of them were unilateral CI users and 31 wore a hearing aid (HA) in the contralateral ear (i.e., bimodal hearing). All subjects were tested for Mandarin tone recognition in quiet and in two types of maskers: speech-spectrum-shaped noise (SSN) and two-talker babbles (TTB) at four signal-to-noise ratios (−6, 0, +6, and +12 dB).
Results
While no differences existed in tone recognition in quiet between the two groups, the Bimodal group outperformed the Unilateral CI group under noise conditions. The differences between the two groups were significant at SNRs of 0, +6, and +12 dB in the SSN conditions (all p < 0.05), and at SNRs of +6 and +12 dB of TTB conditions (both p < 0.01), but not significant at other conditions (p > 0.05). The TTB exerted a greater masking effect than the SSN for tone recognition in the Unilateral CI group as well as in the Bimodal group at all SNRs tested (all p < 0.05). Among demographic or audiometric variables, only age at implantation showed a weak but significant correlation with the mean tone recognition performance under the SSN conditions (r = −0.276, p = 0.045). However, when Bonferroni correction was applied to the correlation analysis results, the weak correlation became not significant.
Conclusion
Prelingually-deafened children with CIs face challenges in tone perception in noisy environments, especially when the noise is fluctuating in amplitude such as the multi-talker babbles. Wearing a HA on the contralateral side when residual hearing permits is beneficial for tone recognition in noise.
