“…Previous studies showed that visual information of the room can improve auditory distance perception (Calcagno et al, 2012) and incongruent audio-visual cues can disrupt distance or externalization percepts (Gil-Carvajal et al, 2016). However, visual information has been shown to not affect the percept of reverberation (Schutte et al, 2019), which is in line with the results from the current study.…”

In multi-talker situation, listeners have the challenge to identify a target speech source out of a mixture of interfering background noises. In the current study it was investigate how listeners analyze audio-visual scenes with varying complexity in terms of number of talkers and reverberation. Furthermore, the visual information of the room was either coherent with the acoustic room or incoherent. The listeners’ task was to locate an ongoing speech source in a mixture of other speech sources. The 3D audio-visual scenarios were presented using a loudspeaker array and virtual reality glasses. It was shown that room reverberation as well as the number of talkers in a scene influence the ability to analyze an auditory scene in terms of accuracy and response time. Incongruent visual information of the room did not affect this ability. When few talkers were presented simultaneously, listeners were able to quickly and accurately detect a target talker even in adverse room acoustical conditions. Reverberation started to affect the response time when four or more talkers were presented. The number of talkers became a significant factor for five or more simultaneous talkers.

“…Data relating to congruent versus incongruent audiovisual stimuli in an auditorium context is scarce, with one study finding that incongruent audiovisual stimuli from different seat locations sometimes but not always results in lower plausibility (Postma & Katz, 2017), one finding that congruent or incongruent audiovisual stimuli from different rooms did not significantly affect distance or room size perception (Maempel & Jentsch, 2013), while another has shown that perception of reverberation in a variety of rooms is not affected when the visual dimensions are altered to make the visual room incongruent with the auditory one (Schutte et al, 2019). In the study of Jeon et al (2008), when crossmatching 3 auditory and visual stimuli with different subjective preferences, a significant interaction was observed, although the effect size was very small compared to the main effects.…”

Separate effects of auditory and visual room size on auditorium seat preference: a virtual reality study

Audiovisual integrations and interactions happen everywhere, including in music concerts, where combined visual and auditory perception contributes to overall enjoyment. Thirty-three participants evaluated their overall subjective preference at various seats in four virtual auditoria, which comprised congruent and incongruent auditory and visual renders of two auditoria that differ only in size. Results show no significant difference between participants who completed the experiment in a fully calibrated and standardized laboratory environment and participants who completed remotely using various VR equipment in various environments. Both visual and auditory auditorium size have significant main effects, but no interaction. The larger hall is preferred for both conditions. Audiovisual congruency does not significantly affect preference.

“…When the sound is far from listeners, reflected sound plays the main role in distance perception, while direct sound still obeys the inverse-square law. But Michael Schutte et al supposed that the estimation of subjects to reverberation did not depend on visual cues [ 26 ].…”

Auditory distance perception is important to virtual sound production and is affected by many factors. In order to investigate the effect of the visual cue on auditory distance perception and the best auditory distance perception in the existence of virtual sound source, experiments on the effect of visual cue on distance perception and the best auditory distance perception were conducted, respectively. The results of the first experiment showed that there was no obvious difference between the auditory distance perception in the existence and absence of virtual sound source, but visual cue can decrease the fluctuation of the perception. From the best auditory distance perception experiment, the attenuating SPL of the initial sound signal that made the subjects perceive the best auditory distance in the existence of virtual sound source at the distance of 4m, 6m, 8m, 10m, and 12m was measured, respectively, and compared the difference of attenuating SPL between experiment measurement and theoretical calculation.
