We present an audio-visual Virtual Reality display system for simulated sound fields. In addition to the room acoustic simulation by means of phonon tracing and finite element method this system includes the stereoscopic visualization of simulation results using a 3D back projection system as well as auralization by use of a professional sound equipment. For auralization purposes we develop a sound field synthesis approach for accurate control of the loudspeaker system. 1998 ACM Subject Classification I.3.5 Computational Geometry and Object Modeling, J.2 Physical Sciences and Engineering Keywords and phrases Special Relativity, Minkowski, Spacetime, Virtual Camera Digital Object Identifier 10.4230/DFU.SciViz.2010.303
