In this paper, we propose a configuration method of 1-2-2 multi-channel active noise control system. The independent components between the reference signals are generally used for the control. Unfortunately, the components are nothing in the 1-2-2 system. We propose a method of inserting the inverse system cancelling the crossing in the secondary path between two noise control filters and two loudspeakers. The two channels are thereby separated, and consequently they can be individually controlled. We finally applied to two sinusoidal noise control systems using the frequency conversion method and the filtered-x LMS (least mean square) algorithm, and also show that the former is superior to the latter. |
