The directional hearing of 20 healthy test persons, all with normal hearing abilities, was tested using a special self constructed equipment. Under the repeated influence of an optokinetic stimulation (rotating light beams on a semicircular screen in a completely darkened room) no statistically significant deviation of the directional hearing reactions could be detected.
使用一种特殊的自制设备对20名听力正常的健康测试者的定向听力进行了测试。在视动刺激（在完全黑暗的房间里，半圆形屏幕上旋转的光束）的反复影响下，未检测到定向听力反应有统计学上的显著偏差。
