Abstract
This paper presents a multiple channel active noise control system using the simultaneous equations method based on the different principle from the filtered-x algorithm. The simultaneous equations method can automatically recover the noise reduction effect degraded by acoustic path changes. In this paper, we apply the method to multiple channel active noise control systems and verify the performance of the systems by computer simulations.
