Claim 5:
6. The adaptive noise-canceling system of claim 5, wherein the adaptive noise-canceling system further comprises:
a reference input electroacoustic transducer for generating the noise reference signal according to noise present in the acoustic environment of the system;
an output electroacoustic transducer for generating an acoustic output including the anti-noise signal from a transducer input signal in the acoustic environment of the adaptive noise-canceling system; and
an error input electroacoustic transducer for generating an error signal according to the acoustic output from the output electroacoustic transducer and ambient noise, and wherein the adaptive filter is responsive to the error signal to provide the second response describing the characteristic of the acoustic environment as a second response modeling a secondary acoustic path from the output of the output electroacoustic transducer to the error input electroacoustic transducer.
