Underground station environment

An audio-visual model for virtual reality of the Munich underground station Theresienstraße. The model has been created for a highly accurate acoustic rendering over loudspeaker arrays and headphones and for visual representation in virtual reality. The package encompasses a highly accurate spatial geometric model of the underground station, which can be used for acoustic simulations, and a visual model for virtual reality. Both models has been calibrated to a 3D laser scan of the environment. It further includes a definition of two acoustic scenes for the purpose of audiology and hearing research together with the associated measurements of the acoustic impulse responses using a binaural recording system (binaural room impulse responses), a spherical microphone array, and omnidirectional microphones. Further measurements include HRTF measurements and anechoic measurements of the directivity of the sound source.
