AbstractExperimental results have clearly shown that the performance of an active control system can be improved by using multiple control channels. A multi-channel system not only increased the attenuation of the control area, but also increased the size of quiet zone. Moreover, it showed that more complex noise sources can be controlled by using a multi-channel system.
