Empirical Evaluation of the Frequency-Dependent Boundary Conditions in a Digital Waveguide Mesh

The digital waveguide mesh is a popular method for time domain acoustic system simulation such as room acoustics. One of the main reasons to choose this paradigm relies in the ease to include boundary conditions in the simulation. This work is focused on the comparison of the simulation with real-world measurements, where a particular scenario is physically built and the corresponding simulation, according to their physical parameters, is carried out. The main scope of this paper is the validation and discussion of a boundary condition model and their correspondence with the measurements through an example.
