Claim 23:
24. The method of claim 23, wherein the acoustic sensor is a reference input electroacoustic transducer that generates the noise reference signal according to noise present in the acoustic environment of the system, and wherein the method further comprises:
generating an acoustic output including the anti-noise signal from a transducer input signal in the acoustic environment of the adaptive noise-canceling system with the output electroacoustic transducer; and
generating an error signal according to the acoustic output from the output electroacoustic transducer and ambient noise from an error input electroacoustic transducer, and wherein the adaptive filter provides 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.
