Matching Perceived Auditory Width to the Visual Image of a Performing Ensemble in Contrasting Multi-Modal Environments

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 spatial congruency and auditory width judgements in dynamic cross-modal environments. The results of these psychophysical tests suggest the importance of consilient audio-visual presentation to the legibility of an auditory scene. Supporting data was accumulated in five rooms of monotonically ascending volumes and varying reverberation times. Participants were given an audio-visual matching test, in which they were instructed to align 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.
