Abstract

In this paper, we propose a feedback active noise control system with noise power scheduling for online secondary path modeling. The proposed method using the VSS-NLMS algorithm yields a faster convergence than conventional feedback ANC systems. Also, utilization of a noise power scheduling results in lower residual noise.Simulation results demonstrate the effectiveness of the proposed approach.
