To assess the accuracy with which cochlear implant patients are able to match two stimuli on the basis of pulse rate pitch.
Patients were required to adjust the pulse rate of a comparison stimulus to match that of a fixed reference stimulus. The comparison and the reference stimuli differed in loudness or were presented to different electrodes.
Patients were able to match stimuli on the basis of pulse rate, with varying degrees of accuracy. Deviations from the target and the amount of variability were greater when stimuli were presented to different electrodes. The results also provide evidence regarding level-dependent pitch shifts.
Because of methodological limitations, conclusions regarding pitch equivalence are limited. However, patients vary significantly in their ability to utilize temporal information.
评估人工耳蜗植入患者基于脉冲率音调匹配两种刺激的准确性。
要求患者调整比较刺激的脉冲率以匹配固定参考刺激的脉冲率。比较刺激和参考刺激在响度上不同，或者呈现给不同的电极。
患者能够基于脉冲率匹配刺激，准确性程度各异。当刺激呈现给不同电极时，与目标的偏差和变异性更大。结果还提供了关于与电平相关的音调偏移的证据。
由于方法学上的局限性，关于音调等效性的结论有限。然而，患者在利用时间信息的能力方面存在显著差异。
