Figure 3. Average distance perception ratings in the reference room and the two rooms that were incongruent with the reference, as a function of source position.

The ratings were obtained in three conditions, with both visual and auditory room cues (VA), and with either visual (V) or auditory room cues only (A). (a) Condition with both visual and auditory room cues across the three rooms. (b) Three tested conditions in the Reference room. (c) Three tested conditions in the Reverberant-Small room. (d) Three tested conditions in the Dry-Large room. The average of the two presentations per listener was used to calculate the across-listener mean, and the error bars show the standard error of the mean across listeners.
