Claim 0:
1. An adaptive noise-canceling system for generating an anti-noise signal from a noise reference signal, the adaptive noise-canceling system comprising:
a feed-forward filter for filtering the noise reference signal to produce the anti-noise signal, wherein the feed-forward filter has a first response controlled by a set of first coefficients;
a measurement subsystem for measuring a characteristic of an acoustic environment of the adaptive noise-canceling system;
a classifier for classifying the characteristic of the acoustic environment of the adaptive noise-canceling system by analyzing an output of the measurement subsystem; and
a controller for providing the set of first coefficients to the feed-forward filter in conformity with an output of the classifier.
