One example of the invention relates to an active noise cancellation (ANC) system for reducing, at a listening position, the power of a noise signal being radiated from a noise source (31) to the listening position. The system comprises: an adaptive filter (22) receiving a reference signal representing the noise signal and comprising an output providing a compensation signal; at least one acoustic actuator (210) radiating the compensation signal to the listening position; and a signal processing device (41-43) configured to evaluate and assess the stability of the adaptive filter. |
