Abstract :	[en] While 3D cinema is becoming more and more established, little effort has focused on the general problem of producing a 3D sound scene spatially coherent with the visual content of a stereoscopic-3D (s-3D) movie. As 3D cinema aims at providing the spectator with a strong im- pression of being part of the movie (sense of presence), the perceptual relevance of such spatial audiovisual coherence is of significant interest. Previous research has shown that the addition of stereoscopic informa- tion to a movie increases the sense of presence reported by the spectator. In this paper, a coherent spatial sound rendering is added to an s-3D movie and its impact on the reported sense of presence is investigated. A short clip of an existing movie is presented with three different sound- tracks. These soundtracks differ by their spatial rendering quality, from stereo (low spatial coherence) to Wave Field Synthesis (WFS, high spatial coherence). The original stereo version serves as a reference. Results show that the sound condition does not impact on the sense of presence of all participants. However, participants can be classified according to three different levels of presence sensitivity with the sound condition impacting only on the highest level (12 out of 33 participants). Within this group, the spatially coherent soundtrack provides a lower reported sense of presence than the other custom soundtrack. The analysis of the participants’ heart rate variability (HRV) shows that the frequency-domain parameters correlate to the reported presence scores.
