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 36):
A packaged microphone device as claimed in  claim 35  wherein the spectrum peak detect block comprises a controller responsive to the activity detector, wherein the controller is configured such that if the activity is above an activity threshold the relevant spectrum signal is not used to determine an indication of resonance frequency or quality factor that is output from the spectrum peak detect block.
