Abstract

This contribution introduces context-dependent quality elements, which have significant influence on perception of an auditory illusion. Binaural synthesis of an acoustic scene via a personalized headphone system is used. The investigated elements are divergent between synthesized scene and listening room, visibility of the scene, and personalization of the system. Two rooms with different acoustic parameters are used as recording and listening room. The test persons listen either to the same room as the listening room or to the other room. The plausibility of the perceived auditory scene is described by the probands with the help of the parameter perceived externality of the auditory event. Because it is unknown if the relevant quality elements are acoustically or visually based, two groups of test persons are used. The first group has no visual cues (dark room), while the second group sees the synthesized source positions and listening room. We have found significant differences in perceived externality depending on the synthesized and listening room, on the two groups, and on personalization of the system.
