Accommodation to virtual sound rendering in a reverberant room with 3DoF and 6DoF interaction

This study investigates the perception of real (loudspeaker) and virtual (binaural rendering through headphones) sound sources in a reverberant room with 3DoF and 6DoF interaction. More specifically, the study looks at the effect of accommodation to the virtual audio rendering while carrying out a listening experiment aimed at evaluating the presence of real and virtual sources. The<br/>experiment contains three blocks of triplets organised as follows: the 10 first triplets always contained one real sound source, the next 25 triplets had only virtual sources, and the 10 last triplets had again one real sound source. The results show that most of the participants correctly identified the presence of the real sound source during the first block, and started to identify virtual sound sources as real ones in the second block, possibly indicating an accommodation<br/>to the virtual rendering. In the third block, participants correctly identified the presence of the real sound source again.
