Observing the limits of visual bias on sound source localization in ventriloquism effect: A case study on sound engineers vs naive listeners

Visual stimuli and its sound stimuli are judged by the human brain together and perceived them as a single event, even if both are assessed by different sensory systems. Also even if these two stimuli are realized in different spatial positions, a human can perceive both stimuli at the same spatial position. Generally, depending on the properties of the stimuli, the visual sensory system dominates the auditory sensory system, and the sound perceptually is heard from the position where the visual is located. Experimental setup in this study was designed to observe this perceptual shift.
