Abstract

Some experiments on active noise control in a three-dimensional room were reported. A 2 by 2 control system was designed using the Image-GA method, and implemented. Experimental results showed that, with the optimally designed control system, significant control reduction can be achieved even in a three-dimensional room with high modal density. Moreover, a randomly configured control system was implemented to further show the effectiveness.
