Claim 0:
1. A vehicle implemented noise-cancellation system, comprising:
a noise-cancellation subsystem disposed in a vehicle, the noise-cancellation subsystem comprising an adaptive filter being adjusted according to a reference signal and an error signal, the adaptive filter outputting a noise-cancellation signal, which, when transduced into a noise-cancellation audio signal by a speaker, reduces road noise within at least one zone within a cabin of the vehicle; and
an entertainment audio monitoring subsystem, configured to:
generate an entertainment audio monitor signal corresponding to audio originating from an entertainment audio system of the vehicle;
disable the noise-cancellation audio signal when an amplitude of the entertainment audio monitor signal is greater than a cancellation disable threshold; and
attenuate the noise-cancellation audio signal when the amplitude of the entertainment audio monitor signal is greater than a cancellation enable threshold, wherein the attenuation of the noise-cancellation audio signal increases relative to the amplitude of the entertainment audio monitor signal when the amplitude of the entertainment audio monitor signal is less than the cancellation disable threshold.
