本文对耳蜗性听力障碍患者时间分辨率的研究进行了综述，目的是评估存在阈值以上缺陷的证据。在比较听力受损(HI)和听力正常(NH)听众的表现时，特别注意变量的作用--例如刺激可听度、总体刺激水平和受试者年龄--这些变量可能会使对实验结果的解释复杂化。在特定的时间任务(例如，间隙检测)上，当与相同SPL时相比，HI听者的性能似乎比NH听者的性能降低。对于其他时间任务(例如，前向掩蔽)，与NH听者相比，在相同的感觉水平下，HI性能降低。然而，有一组相对较小的研究，其中刺激的可听性和水平(有时是受试者的年龄)的影响已经通过使用噪声掩蔽的模拟NH听者的听力损失来控制。对于一些时间任务(包括间隙检测、间隙持续时间辨别和调制噪声中短音的检测)，HI听者的表现在噪声掩蔽的NH听者的结果中得到了很好的再现。对于其他任务(即时间积分)，噪声掩蔽的听力损失模拟不会重现HI听者的结果。在时间加工的另外三个领域(时长辨别、噪声中时间调制的检测和各种时间掩蔽范式)，有必要通过控制刺激的可听性和水平以及年龄来进一步研究，以便更全面地理解超阈值缺陷在高听力听者的时间加工能力中的作用。
A critical review of studies of temporal resolution in listeners with cochlear hearing impairment is presented with the aim of assessing evidence for supra-threshold deficits. Particular attention is paid to the roles of variables—such as stimulus audibility, overall stimulus level, and subject age—that may complicate the interpretation of experimental findings in comparing the performance of hearing-impaired (HI) and normal-hearing (NH) listeners. On certain temporal tasks (e.g., gap detection), the performance of HI listeners appears to be degraded relative to that of NH listeners when compared at equal SPL. For other temporal tasks (e.g., forward masking), HI performance is degraded relative to that of NH listeners when compared at equal sensation level. A relatively small group of studies exists, however, in which the effects of stimulus audibility and level (and occasionally subject age) have been controlled through the use of noise-masked simulation of hearing loss in NH listeners. For some temporal tasks (including gap detection, gap-duration discrimination, and detection of brief tones in modulated noise), the performance of HI listeners is well reproduced in the results of noise-masked NH listeners. For other tasks (i.e., temporal integration), noise-masked hearing-loss simulations do not reproduce the results of HI listeners. In three additional areas of temporal processing (duration discrimination, detection of temporal modulation in noise, and various temporal-masking paradigms), further studies employing control of stimulus audibility and level, as well as age, are necessary for a more complete understanding of the role of supra-thresholds deficits in the temporal-processing abilities of HI listeners.
