| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose a configuration method of 1-n-n multi-channel active sinusoidal noise control system. The independent components between the primary noises detected by noise detection microphones cannot be utilized for 1-n-n multi-channel system, especially controlling sinusoidal noise. We show the method of inserting the simple circuit only eliminating the crossing those of the secondary paths connecting loudspeakers and error microphones. The method can be applied to even the secondary paths including non-minimum phase components. The 1-n-n system is thereby converted to n sets of 1-1-1 systems. We finally confirm by using computer simulations that sinusoidal noises can be reduced by applying the filtered-x LMS (least mean square) algorithm to the active noise control even if the secondary paths were preliminarily estimated with some error. | |
