Active noise control is the method that attenuates the noise, especially at low frequencies. In almost all the case, Filtered-x LMS algorithm is used as its adaptive algorithm. However, Filtered-x LMS algorithm has a fault that cannot follow suit for the change of acoustical transfer function. For this reason, the purpose of this research is modification of Filtered-x LMS algorithm in order to follow up the change of acoustical characteristics. We design new ANC controller by applying optimization algorithm (Least Mean Square Algorithm), and the performance of the controller has been verified on a simulation with MATLAB.
