摘要：
A feedforward active noise control system (50) is provided that includes a reference sensor (16), a secondary source (18), an error sensor (20), and an active noise control system controller (10) for generating an anti-noise signal to attenuate a noise signal provided through a media. The feedforward active noise control system (50) performs on-line feedback path modeling and on-line secondary path modeling.
