Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents an active noise control (ANC) system employing a frequency-domain simultaneous perturbation method with variable perturbation and variable step-size parameters. The proposed system extends the conventional time-domain simultaneous perturbation method, which is effective under disturbance conditions at the error microphone, to the frequency domain. By adaptively adjusting the perturbation and step-size parameters, the proposed system converges rapidly. Simulation results demonstrate that the proposed system achieves significantly faster convergence and superior noise reduction performance compared with conventional systems.
