Despite many studies investigating auditory spatial impressions in rooms, few have addressed the impact of simultaneous visual cues on localization and the perception of spaciousness. The current research presents an immersive audiovisual environment in which participants were instructed to make auditory width judgments in dynamic bi-modal settings. The results of these psychophysical tests suggest the importance of congruent audio visual presentation to the ecological interpretation of an auditory scene. Supporting data were accumulated in five rooms of ascending volumes and varying reverberation times. Participants were given an audiovisual matching test in which they were instructed to pan the auditory width of a performing ensemble to a varying set of audio and visual cues in rooms. Results show that both auditory and visual factors affect the collected responses and that the two sensory modalities coincide in distinct interactions. The greatest differences between the panned audio stimuli given a fixed visual width were found in the physical space with the largest volume and the greatest source distance. These results suggest, in this specific instance, a predominance of auditory cues in the spatial analysis of the bi-modal scene.
尽管有许多研究调查了房间中的听觉空间印象，但很少有研究涉及同时存在的视觉线索对定位和宽敞感的感知的影响。当前的研究提供了一个沉浸式的视听环境，参与者被要求在动态双模态环境中进行听觉宽度判断。这些心理物理测试的结果表明，音频视觉呈现的一致性对于听觉场景的生态解释很重要。在递增容积和变化混响时间的五个房间中积累了支持数据。参与者接受了视听匹配测试，他们被要求将演奏乐团的听觉宽度平移到房间中不同的音频和视觉提示。结果表明，听觉和视觉因素都影响了收集到的反应，并且这两种感觉模态在不同的相互作用中重合。在具有最大容积和最大声源距离的物理空间中，给定固定视觉宽度的平移音频刺激之间的差异最大。这些结果表明，在这种特定情况下，听觉线索在双模态场景的空间分析中占主导地位。
