摘要
Active noise control (ANC) technology is becoming popular in consumer electronic products for audio applications. Typical ANC system aims primarily at reducing acoustic noise over the entire frequency band. However, human factors including diversity of individual listening preferences on spectral content and non-uniform characteristics of human hearing response in frequency domain require the capability of tuning the residual noise spectrum in ANC system. In this paper, we propose a new feedforward ANC structure featuring spectrum-tuning of the residual noise. Analysis shows that this new system has good tuning performance and little influence on system adaptation. Simulation results verify the effectiveness of the proposed system.(1).
