Abstract: Virtual Reality (VR), in combination with acoustical simulations, can be used to create ecologically valid environments of everyday scenes such as classroom scenarios which typically contain various (background) sound sources. To set up an experiment investigating different levels of visual fidelity of such background sound sources in a virtual classroom, efficient rendering strategies for the auralization of the scene's sound sources are required. This work presents and discusses options to implement and configure a binaural real-time room simulation and auralization of a classroom including multiple virtual sound sources using the software Virtual Acoustics in combination with the room acoustic simulation library RAVEN. The visual VR environment used in the conducted experiment is created in the Unreal Game Engine and presented to the participants via head-mounted displays, whose tracking devices make it possible to also account for the user's movements in the headphone-based auralization. Different configurations of the classroom scene, as well as of the acoustic rendering engine and their effects on the system’s performance in the experiment, are presented.
