Effects of visual and vestibular self-motion information on auditory space perception

当我们在一个环境中移动时，我们耳朵的听觉输入会动态变化。这可能会干扰准确的声音定位，因为听觉定位的线索主要是协调和集中在头部。然而，在现实中，我们感知到一个稳定的听觉空间。这就要求大脑将听觉信号与头部和身体运动的信号结合起来进行解释。在这里，我们调查了视觉和前庭自我运动信息如何影响听觉空间知觉。结果表明，在视觉和/或前庭刺激期间，听觉空间的系统性失真，表明听觉系统中的适应性偏差，以避免障碍物和任何传入的危险。

When we move in an environment, auditory input to our ears dynamically changes. This likely interferes with accurate sound localization because cues for auditory localization are primarily coordinated and centered on the head. Nevertheless, in reality, we perceive a stable auditory space. This requires that the brain interpret auditory signals in reference to signals about head and body movements. Here we investigated how visual and vestibular self-motion information affects auditory space perception. The results showed the systematic distortion of auditory space during visual and/or vestibular stimulation, suggesting the adaptive bias in the auditory system to avoid obstacles and any incoming dangers.
