ROOM ACOUSTIC PREDICTION MODELLING
Jens Holger · 2010
The development of room acoustic modelling technique over more than forty years is briefly outlined by introducing the most important methods. An important issue is the scattering properties of surfaces, how they are measured and modelled. Two different cases are used to show some of the challenges to room acoustic computer modelling. The first case is a turbine hall with very large sound sources which cannot be modelled by simple point sources. The other case is a new school project where the entire building model has been imported for acoustic simulations, either in selected rooms, or as a more complex soundscape scenario that includes the sound transmission between rooms.
