感音神经性听力损失的儿童在口语结果上表现出相当大的差异性。我们测试了超阈值听觉知觉的特定缺陷是否可能导致这种差异性。在先前的一项研究中，J.Acoust.SoC。轻至中度感音神经性耳聋(MMHL)儿童在评估对颞叶细微结构(TFS，短时间间隔内窄带信号幅度的快速振荡)敏感性方面的表现比正常听力(NH)对照组更差。然而，他们在评估包络敏感度(E；总体幅度的缓慢波动)的措施上表现在正常范围内。在这里，在控制了非言语智商、语言困难家族史和听力损失严重程度后，个体对TFS的敏感度的差异可以解释MMHL儿童口语能力的显著差异。对于MMHL儿童，TFS和E线索的辅助敏感性同样重要，而对于NH儿童，E线索更为重要。这些发现表明，TFS知觉缺陷可能导致感音神经性耳聋儿童口语结果的差异性。
Children with sensorineural hearing loss show considerable variability in spoken language outcomes. We tested whether specific deficits in supra-threshold auditory perception might contribute to this variability. In a previous study [, J. Acoust. Soc. Am, 146, 4299], children with mild-to-moderate sensorineural hearing loss (MMHL) were shown to perform more poorly than normally hearing (NH) controls on measures designed to assess sensitivity to the temporal fine structure (TFS, the rapid oscillations in the amplitude of narrowband signals over short time intervals). However, they performed within normal limits on measures assessing sensitivity to the envelope (E; the slow fluctuations in the overall amplitude). Here, individual differences in unaided sensitivity to TFS accounted for significant variance in the spoken language abilities of children with MMHL, after controlling for nonverbal IQ, family history of language difficulties, and hearing loss severity. Aided sensitivity to TFS and E cues was equally important for children with MMHL, whereas for children with NH, E cues were more important. These findings suggest that deficits in TFS perception may contribute to the variability in spoken language outcomes in children with sensorineural hearing loss.
