Abstract
This research examines the validity of utilising a 2D multi-plane FDTD acoustic model to simulate low frequency sound propagation as part of a hybrid room impulse response (RIR) synthesis system. Analytic results, pertaining to the comparison of simulated low frequency multi-plane RIRs with both practical RIR measurements and 3D FDTD simulated RIRs, demonstrate that a good level of accuracy is attained through use of this hybrid modelling paradigm. This claim is further supported, in part, by comparative subjective test results. Furthermore, 2D multi-plane simulations are shown to be far more efficient than full 3D FDTD modelling procedures as they achieve a ∼98% reduction in computation time.
