Abstract

Based on three vibrating acceleration signals, using BP neutral network, the noise signal at the driver´s right ear is predicted as reference signal. Applying the adaptive filter, a single channel, feed-forward, self-adaptive controller, as well as an online secondary path model is established and simulated in MATLAB/Simulink. Both the primary signal and the residual signal are exported to the workspace to analyze the loudness improvement. The applied ANC method proves to be effective on loudness improvement.
