Auditory distance perception in real and virtual environments

Abstract

The digital entertainment industry recently knows a major change with the generalisation of 3D video technologies (movies, TV, smartphones). Adding visual depth significantly impacts our multimedia experience. However, little is known regarding the sound technology to associate with this new dimension. Interactions between audio and visual spatial information are poorly investigated as to distance dimension. Before dealing with this bimodal (audio-visual) problem, we need to study each modality independently.
