Power-output regularization in global sound equalization
Schematic diagram of the room for the two-dimensional problem. The sensor plane is at while the coordinates of the centers of the sources are at 0.05, 0.5, 1, 1.5 and . The coordinates of their centers are at for the left sources and at for the right sources.
Variation of the reproduction error as a function of the penalty parameter (solid line) and (dashed line) calculated (a) at the monitor sensors and (b) at the control sensors.
Reproduction error as a function of the frequency (a) at the monitor sensors and (b) at the control sensors. The penalization parameter is for power penalty regularization and for effort penalty regularization. In (a) is also shown the global reproduction error for global sensing.
(a) Total sound power output of the reproduction sources as a function of the frequency and (b) total source effort. The mode notation in (a) is .
Distribution of the sound pressure level in dB at using (a) effort regularization and (b) power-output regularization. The sound pressure is shown only at positions where the deviations of the reproduced sound pressure from the desired pressure are within . The positions of the control sensors are marked with white dots.
