A noise reduction system includes a microphone configured to detect an acoustic signal. A first digitizer converts an output of the microphone into a discrete output signal. An acoustic sensor detects structure-borne noise, and a second digitizer converts an output of the acoustic sensor into a discrete acoustic noise reference signal. A noise compensation circuit processes the discrete output signal based on the discrete acoustic noise reference signal.
