Two experiments, with a total of 220 Ss, were conducted to investigate the possibility of illusory movement of a sound source. In Experiment 1 intensity level (from 10 to 60 db SPL) and frequency of an auditory sound (from 1000 to 5000 Hz) were varied while the Ss head was stabilized with a head rest; in Experiment 2, intensity and frequency were also varied while the S's head was free to move. When head position was fixed, error signal variables such as intensity had no effect on the frequency of illusory direction changes of a sound source. However, when the head position was not fixed, increasing the intensity of the sound source significantly decreased the number of reported illusory direction changes. In addition, in both experiments, illusory changes of intensity were experienced by Ss, and increasing the intensity of the sound source also decreased this illusion. The results were interpreted in the context of an error signal and noise model of autokinetic effects, and the implications for the perception of auditory localization and movement of a sound source were discussed.
进行了两项实验，共有220名受试者，以研究声源错觉运动的可能性。在实验1中，当受试者头部用头托固定时，改变听觉声音的强度水平（从10到60分贝声压级）和频率（从1000到5000赫兹）；在实验2中，当受试者头部可以自由移动时，也改变强度和频率。当头部位置固定时，诸如强度等误差信号变量对声源错觉方向变化的频率没有影响。然而，当头部位置不固定时，增加声源强度会显著减少报告的错觉方向变化的数量。此外，在两项实验中，受试者都经历了强度的错觉变化，增加声源强度也减少了这种错觉。研究结果在自动运动效应的误差信号和噪声模型的背景下进行了解释，并讨论了其对声源听觉定位和运动感知的影响。
