A method to examine audiospatial integration was developed through studies of normal and brain-injured patients. The method used a sound source sequentially outlining a spatial pattern within an array of 100 loudspeakers. For 48 subjects tested with this method, the presence or absence of visual cues had no effect in audiospatial processing. Eye movements also did not match the perceived sound patterns. Significantly higher hit rates were obtained by placing the panel of loudspeakers in front, behind or above the subject rather than on the left or right. These differences were observed with involuntary but not with voluntary head-fixation. Theoretical concepts of audiospatial processing are discussed.
通过对正常人和脑损伤患者的研究，开发出一种检测听觉空间整合的方法。该方法使用一个声源依次勾勒出由100个扬声器组成的阵列中的空间模式。用这种方法测试的48名受试者中，视觉线索的有无对听觉空间处理没有影响。眼球运动也与感知到的声音模式不匹配。将扬声器面板放置在受试者前方、后方或上方时，命中率显著高于放置在左侧或右侧时。这些差异在非自愿头部固定时观察到，而在自愿头部固定时未观察到。文中讨论了听觉空间处理的理论概念。
