摘要

•FMBEM and FDTD are benchmarked in room acoustic modelling and simulations.•The model uncertainties of using the two solvers are presented and studied.•The two solvers are evaluated with increasing complexity of material input properties.•Both FMBEM and FDTD can give close predictions in most of the scenarios.•Input material data results in large deviations between simulation and measurement.
