This PhD project aims to be a step towards a better understanding and prediction of the sound propagation in open plan spaces by implementing, further developing and validating room acoustics modelling techniques. Since state-of-art room acoustic modelling approaches, mostly based on geometrical acoustics, could lead to incorrect predictions in open plan spaces, this research aims to contribute with other acoustic modelling approaches for large open (interconnected) spaces, including non-line-of-sight source-receiver paths. The wave-based approach, time-domain discontinuous Galerkin (DG) method, will be further developed for the purpose of room acoustic modeling.
