A system and method for reduce noise emitted by a printer are disclosed herein. In one embodiment, a sound detector (404) disposed proximate to a noise source (402) detects a measured noise signal, which is analyzed (410) to determine one or more resonant frequencies thereof. A feedback signal is determined (414) based on the analyzed noise signal and is used to generate (416) a compensated signal 180 degrees out of phase with the feedback signal. The compensated signal is output (420) proximate to the noise source.
