Listeners were required to locate, monaurally, noise bursts emanating from the horizontal plane ipsilateral to the functioning ear. Loudspeakers were positioned from 0 through 180 degrees azimuth, separated by 15 degrees. Stimulus bandwidth was 1.0 kHz, and centered at 4.0-14.0 kHz in steps of 0.5 kHz. The location judgments were governed by the frequency composition of the stimuli, not by their place of origin. With a miniature microphone positioned at the entrance of the external ear canal, the relative amplification provided by the pinna was obtained for the stimuli employed in the localization tests. For each differently centered noise burst, that loudspeaker position re other positions which was associated with the greatest amplification of the stimulus was the one most likely to have been chosen as the source of that stimulus during the localization tests.
要求听众单耳定位来自与正常耳同侧的水平面发出的噪声脉冲。扬声器在方位角0度到180度之间定位，间隔为15度。刺激带宽为1.0kHz，以0.5kHz为步长，中心频率在4.0 - 14.0kHz之间。位置判断由刺激的频率成分决定，而非其来源位置。通过将一个微型麦克风置于外耳道入口处，获取耳廓对定位测试中所使用刺激的相对放大情况。对于每个中心频率不同的噪声脉冲，在定位测试期间，与刺激最大放大相关联的那个扬声器位置相对于其他位置，是最有可能被选为该刺激源的位置。
