Coupled Meta-Adaptive Filtering for Active Noise Control Under Time-Varying Acoustic PathsNew

The paper addresses active noise control in acoustics under time-varying acoustic paths. It uses meta-adaptive filtering to replace hand-crafted adaptive-filter updates with a learned optimizer during online adaptation. The optimizer features are constructed from a secondary-path estimate, and mismatch between this estimate and the changing physical path can reduce filter-update accuracy and noise-control performance.
