之前，据报道，患有大量高频听力损失的听众难以在正中矢状面中定位声音[Vander Velde等人，1812（A）（1993）]。当被要求定位宽带噪声时，他们在仰角任务中的表现接近偶然水平，在要求他们区分前方、头顶和后方的任务中表现稍好，但远低于正常水平。在本研究中，这些实验重复与新的主题（n=16），并与以下的变化，每一个引入，以鼓励提高性能。(1)噪声刺激的低频分量被滤除，以防止屏蔽更多信息的高频分量。(2)提升任务的难度降低了。(3)受试者在佩戴助听器时接受测试。这些变化中的每一个都帮助了一些人，通常是在小的方面，但没有一个对整个群体产生统计学上的显著改善（p <0.05）。在一起，...
Previously, it was reported that listeners with substantial high‐frequency hearing loss have difficulty localizing sounds in the median sagittal plane [Vander Velde et al., 1812(A) (1993)]. When asked to localize broadband noise, they performed near chance level on an elevation task and somewhat better, but far below normal, on a task that required that they distinguish between sources to the front, overhead, and rear. In the present study, these experiments were repeated with new subjects (n=16), and with the following variations, each introduced to encourage improved performance. (1) Low‐frequency components of the noise stimulus were filtered out to preclude the masking of more informative high‐frequency components. (2) The difficulty level of the elevation task was eased. (3) Subjects were tested while wearing their hearing aids. Each of these changes helped a few individuals, typically in small ways, but none produced statistically significant improvement for the group overall (p≳0.05). Together, the...
