Abstract: A noise reducing sound reproduction system and method may be operable with an input signal supplied to a loudspeaker by which it is acoustically radiated. The signal radiated by the loudspeaker may be received by a microphone that is acoustically coupled to the loudspeaker via a secondary path and that provides a microphone output signal.

The filter input signal is filtered in an active noise reduction filter to generate an error signal, and the useful-signal is subtracted from the error signal to generate the loudspeaker input signal. In addition, the useful-signal is filtered by one or more spectrum shaping filters prior to subtraction from the microphone output signal or the loudspeaker input signal or both.
