In this Final Task, will implementing multiple-channel hybrid ANC system for open air acoustic using FXLMS algorithm to produce anti-noise signal. ANC system in this Final Task will use noise signal from the sine single tone dan dual tone. The activities on this Final Task are simulating algorithm using MATLAB, identifying nultiple channel ANC secondary model and controlling multiple channel desentralitation and sentralitation ANC system. The experimental results shows that to accomplish good performance of ANC the selection of learning step value, number of order and geometrical aspect should be carefully considered. <br />
