Typical active noise control (ANC) system aims primarily at reducing the acoustic noise over the entire frequency band. Non-uniformity of human hearing response in frequency domain and diversity of individual preference for spectral content require tuning of the residual noise spectrum in ANC system. In this paper, we propose a new ANC structure featuring spectrum-tuning of the residual noise. Simulation results show good tuning performance and little influence on system adaptation for the proposed system.
