Active Noise Cancellation, System Identification, Secondary path.
In this paper, The necessity of a proper modeling of acoustic path for an Active Noise Cancellation (ANC) system, and the impact of modeling error on system performance is discussed. Firstly , a physical model is assumed for the acoustic path that can be used as reference for further modeling, and then with the aid of the data obtained from a laboratory enclosure, an appropriate transfer function is derived. At the effect of modeling error on noise reduction is explored.
