| Popis: | International audience; Audio-only Augmented Reality (AAR) consists in enhancing a real environment with virtual sound events. A seamless integration of the virtual events within the environment requires processing them with artificial spatialization and reverberation effects that simulate the acoustic properties of the room. It is known, for instance, that the room effect has a strong influence on the perception of sound source distance. Consequently, in the context of AAR, an important issue is to guarantee that the perceived distance of the virtual events is coherent with the room geometry and the position of the real sound sources present in the room. This calls for the choice of a distance rendering model and the access to a priori information about the acoustical properties of the room. This study focuses on the perceptual evaluation of different room effect rendering models informed by a single or a limited number of Directional Room Impulse Responses (DRIR). These models simulate the missing positions/distances by generating a new DRIR through several modifications of the measured one. The perceptual performances of the proposed models are compared to reference situations based on Binaural Room Impulse Responses (BRIR) measured at each reconstructed distance. The results are compared with bibliographic studies on auditory distance perception. |
