Resumo
The Virtual Concert Hall is a virtual environment that has been specifically designed for the optoacoustic
simulation of performance rooms. As a tool for experimental research, its design is derived from particular
methodological demands including harvesting comparable acoustical and optical information, dissociating the
space and content of multisensory events,varying optical and acoustical room properties in a mutually
independent manner, while also providing a full set of stimulus cues. The system features 3D sound and
vision by applying dynamic inaural synthesis and a 161°stereoscopic projection on a cylindrical screen. Room
simulation data were acquired in situ in the form of orientational binaural room impulse responses and
stereoscopic panoramic images. Music and speech performances were recorded acoustically in an anechoic
room and optically in a greenbox studio and inserted into the virtual rooms. The Virtual Concert Hall provides
nearly all perceptually relevant acoustical and optical cues, enabling experiments on the audiovisual
perception of optoacoustically conflicting rooms under rich-cue conditions.
