This work examines the performance of both offline and online secondary path modeling
algorithms that are used in narrowband active noise control (NANC) systems. Theoretical …

Several approaches have been introduced in the literature for active noise control (ANC)
systems. Since the filtered-x least-mean-square (FxLMS) algorithm appears to be the best …

This paper proposes a new structure for feedforward active noise control (ANC) systems with
online secondary path modeling. The proposed method: 1) uses the same error signal for …

The filtered-x least mean square based narrowband active noise control (FX-NANC) system
with a parallel structure is typically used to cancel low-frequency multi-tonal noise. The …

This paper investigates estimation of the secondary path (SP) during the online operation of
the filtered-x least mean square (FxLMS) algorithm-based feedback active noise control …

Abstract A Hybrid Active Noise Control (HANC) system is used to attenuate disturbances in a
scenario where a portion of noise is captured by reference sensors. In such scenarios, the …

Many noise reduction applications are targeted at multi-tonal disturbances. Active noise
control (ANC) solutions for such problems are generally based on the combination of …

Online feedback path modeling and neutralization (FBPMN) is vital in active noise control
(ANC) systems to ensure stability and elevate performance in non-stationary environments …

A method to improve the performance of the secondary path modeling for active noise
control systems is proposed in this letter. The proposed method can further reduce the …

The presence of strong acoustic feedback degrades the performance of active noise control
(ANC) systems, and in the worst case the ANC system may become unstable. In this paper …
