Abstract

International audience; Studies on audiovisual interactions in sound localization have primarily focused on the relations between the spatial position of sounds and their perceived visual source, as in the famous ventriloquist effect. Much less work has examined the effects on sound localization of seeing aspects of the visual environment. In this study, we took advantage of an innovative method for the study of spatial hearing-based on real sounds, virtual reality and real-time kinematic tracking-to examine the impact of a minimal visual spatial frame on sound localization. We tested sound localization in normal hearing participants (N = 36) in two visual conditions: a uniform gray scene and a simple visual environment comprising only a grid. In both cases, no visual cues about the sound sources were provided. During and after sound emission, participants were free to move their head and eyes without restriction. We found that the presence of a visual spatial frame improved hand-pointing in elevation. In addition, it determined faster first-gaze movements to sounds. Our findings show that sound localization benefits from the presence of a minimal visual spatial frame and confirm the importance of combining kinematic tracking and virtual reality when aiming to reveal the multisensory and motor contributions to spatial-hearing abilities.
