Abstract | Previous research has shown that a reflective surface has an impact on the control performance of an active noise control system. System identification of the secondary path is of utmost importance in the effectiveness of the control branch of an active noise control system. It is thus essential to accurately model the secondary path with the right number of filter coefficients to have acceptable performance results. In this paper, the effect of a reflective surface on the impulse response of the secondary path of a single channel ANC system is outlined and discussed. Experiments show that the reflective surface indeed has an effect on the impulse response and can affect the performance of the system. The orientation of this reflective surface can be selected in order to optimize the impulse response of the secondary path for best results. |
