Claim 8:
9. The adaptive noise-canceling system of claim 6, further comprising:
a source of audio information for reproduction by the output electroacoustic transducer;
a first combiner that combines the program audio with the anti-noise signal to provide the transducer input signal; and
a second combiner that removes the program audio from the output of the adaptive filter to generate the error signal, whereby the classifier classifies the second coefficients of the response of the adaptive filter modeling the secondary acoustic path from the acoustic output of the output electroacoustic transducer to an output of the error input electroacoustic transducer and applies the classification to predict a required first response of the feed-forward filter.
