Abstract:
This application describes a noise reduction apparatus ( 800 ) for a microphone device ( 100 ) having an acoustic port ( 110 ). The apparatus has a spectrum peak detect block ( 301 ) for receiving a microphone signal (S MIC ) and determining, from the microphone signal, at least one characteristic of a resonance peak ( 202 ) associated with the acoustic port of the microphone. The at least one characteristic may comprise a resonance frequency (f H ) and/or quality factor (Q H ). A noise reduction block ( 801 ) is configured to process the microphone signal based on the resonance characteristic so as to reduce noise in the processed microphone signal due to said resonance. The noise reduction block may apply a function which is the inverse of the determined resonance characteristic.

Claim (Index 17):
An apparatus as claimed in  claim 1  wherein the at least one characteristic of a resonance peak associated with the acoustic port of the microphone comprises a resonance frequency and a quality factor of the resonance associated with the acoustic port, the apparatus further comprising a condition monitoring block configured to determine any change in resonance frequency and quality factor with respect to respective reference values of resonance frequency and quality factor and to determine an operating condition for the microphone based on said detect changes;\n wherein the operating condition comprises at least one of: a blockage status of the acoustic port and an air temperature condition.
