Replicating real-world audio experiments in virtual reality

Abstract Perceptual experiments play an important role in research and development of audio technology. Until recently, they were almost always location-dependent, which means that an experiment could be done only in certain rooms or places resulting in a reduced reproducibility. In the last years, development in computer graphics, virtual acoustics, and electronics enabled us to experience virtual reality (VR). Theoretically, a detailed audiovisual model of a room should provide a VR environment with 6 degrees of freedom, where real-world experiments could be replicated with reduced hardware effort all around the world. This thesis creates a detailed visual model of the IEM CUBE and its surrounding loudspeaker system, as well as an acoustic model based on distributed measurements, and simulations. Finally, an experiment that has been done in the CUBE some years ago will be replicated in VR to investigate the plausibility of the models.
