Abstract
A harmonic cancellation system including a feedback sensor, a controller, and a speaker is provided. The feedback sensor is disposed within a cancellation zone within a cabin of a vehicle. The feedback sensor produces a feedback signal corresponding to audio within the cancellation zone. The controller is configured to produce a harmonic cancellation signal that, when transduced into an acoustic signal, reduces audible harmonics from a harmonic noise source at a harmonic frequency within the cancellation zone. The harmonic cancellation signal is adjusted according to a comparison of the feedback signal at the harmonic frequency to at least one of a saturation threshold or the feedback signal at one or more sideband frequencies offset from the harmonic frequency. The speaker is disposed within the cabin, receives the harmonic cancellation signal, and transduces the harmonic cancellation signal into an acoustic harmonic cancellation signal within the cancellation zone.
