The perceived location of events occurring in a mediated environment modulates the users’ understanding and involvement in these events. Previous research has shown that when spatially discrepant information is available at various sensory channels, the perceived location of unisensory events might be altered. Tactile “capture” of audition has been reported for lateral sounds. The present study investigates whether auditory localization on the median plane could be altered by concurrent whole-body vibration. Sounds were presented at the front or the back of participants, in isolation or together with vibrations. Subjects made a three alternative forced choice regarding their perceived location of sound (“front”, “back” or “center”). Results indicate that vibrations synchronous with sound affected subjects’ sound localization, significantly reducing the accuracy on front sound localization in favor of “back” and “center” responses. This research might have implications for the design of multimodal environments, especially for those aiming at creating a sense of presence or inducing affective experiences in users.
