Previous experiments using trains of high-frequency filtered clicks have shown that for lateralization based on interaural difference of time or level, there is a decline in the usefulness of interaural information after the signal's onset when the clicks are presented at a high rate. This process has been referred to as "binaural adaptation." Of interest here are the conditions that produce a recovery from adaptation and allow for a resampling of the interaural information. A train of clicks with short interclick intervals is used to produce adaptation. Then, during its course, a treatment such as the insertion of a temporal gap or the addition of another "triggering" sound is tested for its ability to restart the binaural process. All of the brief triggers tested are shown to be capable of promoting recovery from adaptation. This suggests that, while the binaural system deals with the demands of high-frequency stimulation with rapid adaptation, it quickly cancels the adaptation in response to stimulus change.
先前使用高频滤波后的短声序列进行的实验表明，对于基于耳间时间或强度差异的声音定位，当以高频率呈现短声时，信号开始后耳间信息的有效性会下降。这一过程被称为“双耳适应”。这里感兴趣的是能够从适应中恢复并允许重新采样耳间信息的条件。使用具有短点击间隔的短声序列来产生适应。然后，在适应过程中，测试诸如插入时间间隙或添加另一个“触发”声音等处理方法重启双耳处理过程的能力。所有测试的短暂触发因素都显示能够促进从适应中恢复。这表明，虽然双耳系统通过快速适应来应对高频刺激的需求，但它会根据刺激变化迅速消除适应。
