Description

Architectural room models used for auralization are typically created with different geometric levels of detail (LOD), which directly affect both the surface areas and the effective scattering behaviour, and thus introduce uncertainty into room acoustic simulations. This study reviews the influence of geometric LOD on the choice of scattering and proposes a compensatory modelling strategy for auralization. Two auditoria are investigated as case studies: the Gasteig philharmonic hall in Munich and the chamber music hall of the Konzerthaus in Berlin. An overview of the modelling challenges and the auralization opportunities will be given.
