Active Control of Vehicle Interior Noise Based on Selective Attenuation Method

Based on the Least Square Mean method which is broadly applied on the active noise control technology, the paper calculated the frequency selective LMS algorithm and created the model for the application of the algorithm on active noise control; and was modeled and analyzed the adaptive attenuation simulation with single tone noise signal and narrow band noise signal demonstrating on the platform of Matlab/Simulink, after the control parameters of filter performance parameters and step size and filter length of adaptive filter was decided. The simulation result showed obvious counteract effect of noice signal, it was identical with theoretic solution and the presented algorithm was valid.
