    Abstract

    A multi-channel narrowband feedforward Active Noise Profiling (ANP) system using a modified Filtered-x Least Mean Squares (FXLMS) algorithm has been developed in a passenger car to profile the low-frequency noise components. In practice, the performance of the ANP system will be affected mainly by the accuracy of the plant estimate, the convergence speed, and also the robustness of the ANP algorithm. During the first experiments, the practical ANP system has already been proven to some extent to be effective to modify the periodic noise, specifically the 2nd order engine harmonic. However, because of the complexity of acoustic environment inside the car and the frequency dependent convergence behavior of the algorithm, more work needs to be focused on the optimization of plant estimate and the ANP algorithm to improve the performance of the ANP system
