Virtual auditory environments (VAEs) can be explored by controlling the position and orientation of an avatar and listening to the scene from its changing perspective. Reverberation is essential for immersion and plausibility as well as for externalization and the distance perception of the sound sources. These days, room simulation algorithms provide a high degree of realism for static and dynamic binaural reproduction. In this investigation, the ability of people to discriminate listening positions within a virtual room is studied. This is interesting to find out whether the state of the art room simulation algorithms are perceptually appropriate, but also to learn more about people’s capability of orientating themselves within a purely acoustical scene. New findings will help designing suitable VAEs.
