在动态的3D空间中，感知物体的大小并根据与观察者的距离对其进行缩放是生存的关键。人类不仅可以通过视觉来感知距离，还可以通过听觉来感知距离，听觉在物体定位中起着重要作用，特别是在视觉模糊的环境中。然而，听觉距离信息是否以及如何有助于视觉尺寸感知还没有得到很好的理解。为了解决这个问题，我们调查的效率，大小距离缩放，通过使用听觉距离的信息，传达的双耳记录的听觉刺激。我们研究了一个单一的声音序列的绝对距离信息（实验1）和两个声音序列之间的相对距离信息（实验2）在黑暗和光线充足的环境中对视觉尺寸估计性能的影响。我们证明了人类即使在黑暗中也可以通过使用听觉距离信息来执行大小距离消歧。奇怪的是，相对距离信息在尺寸距离缩放中比绝对距离信息更有效，这表明我们的视觉空间体验高度依赖于相对听觉距离信息。结果突出了视听互动的大小距离处理和校准的外部事件下视觉退化的情况下的好处。
In the dynamic 3D space, it is critical for survival to perceive size of an object and rescale it with distance from an observer. Humans can perceive distance via not only vision but also audition, which plays an important role in the localization of objects, especially in visually ambiguous environments. However, whether and how auditory distance information contributes to visual size perception is not well understood. To address this issue, we investigated the efficiency of size–distance scaling by using auditory distance information that was conveyed by binaurally recorded auditory stimuli. We examined the effects of absolute distance information of a single sound sequence (Experiment 1) and relative distance information between two sound sequences (Experiment 2) on visual size estimation performances in darkened and well-lit environments. We demonstrated that humans could perform size–distance disambiguation by using auditory distance information even in darkness. Curiously, relative distance information was more efficient in size–distance scaling than absolute distance information, suggesting a high reliance on relative auditory distance information in our visual spatial experiences. The results highlight a benefit of audiovisual interaction for size–distance processing and calibration of external events under visually degraded situations.
