Voice sensing using multiple microphones

An in-ear noise cancelling headset comprising:

• an earpiece comprising a feedback microphone (104) and an output driver (112);
• a feedback loop receiving a first signal from the feedback microphone and providing an antinoise signal, based on the first signal, to the output driver,
• the feedback loop including a feedback compensation filter (402, 404) that receives the first signal and produces the antinoise signal,
• wherein, at frequencies at which voice sounds produced by the wearer of the headset tend to be amplified within an occluded ear canal, the feedback compensation filter produces antinoise at levels selected to counteract such amplification without otherwise cancelling the voice sounds;
• a voice output circuit receiving the first signal from the feedback microphone,
• the voice output circuit including a voice output filter that receives the first signal and produces a voice-filtered signal;
• and
• a communications interface providing the voice-filtered signal as a voice communication signal output from the headset.
