Simulation and Visualization of Room Compensation for Wave Field Synthesis with the Functional Transformation Method

Active room compensation based on wave field synthesis (WFS) has been recently introduced. So far, the verification of the compensation algorithm is only possible through elaborate acoustical measurements. Therefore, a new simulation method is applied that is based on the functional transformation method (FTM). Compared with other simulation techniques, the FTM provides several advantages that facilitate the correct simulation of the complete wave field particularly in the interesting frequency ranges for WFS. The complete procedure, starting from the virtual "measurements" of the acoustical properties of the simulated room, via the correct excitation for the simulated wave field, towards the resulting animations and sounds is presented in this paper.
