背景远程麦克风(RM)系统旨在减少不良声学对语音理解的影响。然而，当使用助听器(HAS)和RM系统时，研究在噪声中添加混响对语音理解的影响的研究有限。鉴于恶劣的声学环境给重听儿童带来的巨大挑战，我们评估了一种新型的RM系统解决噪声和混响影响的能力。目的我们评估最近开发的一种RM系统对噪声和混响中的重听儿童的辅助言语感知的影响，以及他们的表现与听力正常的同龄人(即听力阈值不超过15 dBHL的儿童)相比如何。研究样本22名轻度至重度听力损失儿童和17名非重听儿童(即听力阈值不超过15 分贝HL)(7-18岁)。数据收集和分析采用自适应程序确定在噪声和噪声加混响(RT 300 ms)下50%和95%正确句子识别的信噪比。用线性混合模型检验听力条件对两组儿童RMS语音识别的影响，以及助听对重听儿童在所有听力条件下的表现的影响。结果重听儿童单独使用HAS的语音识别能力比HAS加Rm的更差。无论听力状况如何，儿童在噪音加混响中的语音识别能力都比单独在噪音中差。在单独使用HAS时，听力障碍儿童的语音识别能力比阈值不超过15 dBHL的同龄人差，但与HAS加RM的语音识别能力相当或更好。听力较好的儿童在单独使用HAS和HAS+RM的情况下表现出更好的语音识别能力。结论提供HAS可以最大限度地提高语音可听性，并将它们与RM系统相结合，有可能改善在噪声和混响环境中听力较差的儿童的沟通途径和结果。
BackgroundRemote-microphone (RM) systems are designed to reduce the impact of poor acoustics on speech understanding. However, there is limited research examining the effects of adding reverberation to noise on speech understanding when using hearing aids (HAs) and RM systems. Given the significant challenges posed by environments with poor acoustics for children who are hard of hearing, we evaluated the ability of a novel RM system to address the effects of noise and reverberation.PurposeWe assessed the effect of a recently developed RM system on aided speech perception of children who were hard of hearing in noise and reverberation and how their performance compared to peers who are not hard of hearing (i.e., who have hearing thresholds no greater than 15 dB HL). The effect of aided speech audibility on sentence recognition when using an RM system also was assessed.Study SampleTwenty-two children with mild to severe hearing loss and 17 children who were not hard of hearing (i.e., with hearing thresholds no greater than 15 dB HL) (7–18 years) participated.Data Collection and AnalysisAn adaptive procedure was used to determine the signal-to-noise ratio for 50 and 95% correct sentence recognition in noise and noise plus reverberation (RT 300 ms). Linear mixed models were used to examine the effect of listening conditions on speech recognition with RMs for both groups of children and the effects of aided audibility on performance across all listening conditions for children who were hard of hearing.ResultsChildren who were hard of hearing had poorer speech recognition for HAs alone than for HAs plus RM. Regardless of hearing status, children had poorer speech recognition in noise plus reverberation than in noise alone. Children who were hard of hearing had poorer speech recognition than peers with thresholds no greater than 15 dB HL when using HAs alone but comparable or better speech recognition with HAs plus RM. Children with better-aided audibility with the HAs showed better speech recognition with the HAs alone and with HAs plus RM.ConclusionProviding HAs that maximize speech audibility and coupling them with RM systems has the potential to improve communication access and outcomes for children who are hard of hearing in environments with noise and reverberation.
