AB  - Multi-Actuator Panel (MAP) loudspeaker arrays are advantageously used for wave field synthesis applications in the multi-media domain. However, due to their large dimensions they reflect each others sound waves, thus blurring the synthesized wave field. Furthermore, the MAPs have a very irregular initial frequency response, resulting in a highly coloured and unnatural sound. Filters for reflection elimination and equalization have been derived from impulse responses measured under anechoic conditions. These filters are based on inversion in the frequency domain, using a singular value decomposition method to avoid instabilities. It is shown how such filters can also be designed based on simulated data, thus avoiding the rather elaborate panel transport and measurement procedure. The performance of several filter types has been evaluated and compared physically and perceptually. The simulation-based filters appear to be a promising tool for further MAP performance optimization.
