Abstract

See full text

An audio appliance includes a microphone transducer having an acoustically sensitive region to convert incident acoustic energy to a corresponding output signal and a barometric transducer having a pressure-responsive region to convert an ambient pressure to a corresponding output signal. The audio appliance also has an acoustic housing defining a chamber to fluidly couple the microphone transducer with the barometric transducer, together with a processor and a memory containing instructions. The instructions, when executed by the processor, cause the audio appliance to determine a presence or an absence of an ambient impairment to the microphone transducer based at least in part on the output signal from the barometric transducer. Responsive to a determined presence of an ambient impairment to the microphone transducer, the instructions, when executed by the processor, cause the audio appliance to mitigate effects of the ambient impairment.
