Few studies have investigated the influence of visual cues on sound space perception beyond the influence of visual cues on sound source position. Previous studies suggest that the perception of late reflections is not affected by the visual impression of a room; however, only a limited number of spatial sound attributes were investigated. In the present paper, audiovisual interactions were examined without making assumptions on the number and nature of perceptual dimensions involved in the perception of sound space. In a virtual environment that employed a Head Mounted Display and dynamic binaural playback, subjects were asked to judge the perceived dissimilarity between sound spaces while watching the same visual stimulus. Pairwise comparisons were repeated using multiple visual conditions, including an audio-only condition. One sound source, a male voice reciting a poem, was considered in the listening test. It appeared that the visual modality did not impact the perceived differences between sound spaces.
