In the presence of non-Gaussian impulsive noise (IN) with a heavy tail, active control (ANC) algorithms often encounter stability problems. While adaptive filters based on higher-order error power principle have shown improved filtering capability compared to least mean square family for IN, however, performance filtered-x absolute third (FxLMAT) algorithm tends degrade under high impulses. To ...

This paper investigates the effect of changes in environment on performance two widely-used virtual sensing methods for active noise control (ANC): remote-microphone method and additional-filter method. Robust adaptive feedforward algorithms incorporating such techniques is essential to achieving attenuation at designated locations practice, when subject uncertainties environment. Off-line simu...
