Wave-based room acoustic simulations of an open plan office

Abstract

In this study, room acoustic simulations of a real open plan office using the time-domain discontinuous Galerkin (TD-DG) method are performed, as a preliminary attempt to assess the accuracy and applicability of this wave-based method for realistic sound field analysis in the low-frequency range. This TD-DG simulation involves the developed techniques of locally-reacting frequency-dependent impedance boundary conditions and the local-time stepping scheme. The required input for the boundary modeling of relevant absorption materials is obtained from the absorption coefficients measured in a reverberation room based on the international standard ISO 354. Observed discrepancies, in terms of the room acoustic parameters, between the measurements and simulation results indicate the limitation of the detailed wave-based modeling in the absence of a precise boundary characterization.
