In this paper, we propose a method for stabilizing the noise reduction effect fluctuation causing when the coefficients of the noise control filter are updated by using the simultaneous equations method. The fluctuation is caused by the envilonmental noise arriving at the error microphone.and the components not satisfying the causality. In this paper, we introduce a method for steadily reducing the estimation error caused by the envilonmental noise to the designed level, and then propose a method for pausing the updating the coefficients of the noise control filter when the unsatisfying components increase. We finally verify that the fluctuation cab be sppressed by the propose methods. |
