Abstract:
This application describes an apparatus ( 300 ) for monitoring for blockage of an acoustic ( 110 ) port of a microphone device ( 100 ). The apparatus has a spectrum peak detect block ( 301 ) for receiving a microphone signal (S MIC ) and determining, from the microphone signal, a resonance frequency (f H ) and a quality factor (Q H ) of a resonance ( 202 ) associated with the acoustic port. A condition monitoring block ( 302 ) is configured to determine any change in resonance frequency and quality factor and to determine a blockage status for the microphone based on said detect changes. The condition monitoring block identifies a change in blockage status if there is a change in quality factor.

Claim (Index 32):
A packaged microphone device as claimed in  claim 31  wherein the resonance frequency detection block is configured to identify a signal magnitude range between the highest and lowest signal magnitudes within the predefined frequency range, determine a first threshold within the identified signal range and integrate the values of signal magnitude above the first threshold across the predefined frequency range to identify a first frequency at which the integral equals half of the total integral and identify said first frequency as the resonance frequency.
