Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a selective fixed filter sub-band ANC system with power estimation. The proposed system divides the reference signal obtained inside the system into multiple sub-bands, and selects the noise control filters which correspond to the frequency band with large noise power. In addition, the proposed system can track noise changes immediately based on the selection of the appropriate noise control filters every 0.5 ms. Simulation results with actual impulse responses show that a noise reduction of more 25 dB is possible even when noise characteristics change rapidly.
