Abstract

Ease of adaptive filter techniques of its implementation introduce various active noise control (ANC) systems, using different algorithms for efficient and effective acoustic noise control. Filtered-x least mean square (FxLMS) ANC system is used due to secondary path timing delay. In this paper comparison between feed-forward and feedback active noise control system using FxLMS algorithm is done for the two types of noises a) narrowband and b) broadband noise. For this comparison step-size parameter and filter order is assumed to be constant. Mean square error (MSE) for each case is shown to conclude the usefulness of system.
