[QUOTE="John Roberts, post: 112957, member: 126"] Re: Noise-Cancelling Com headset mic Of you want to really play cheap you can try rolling your own... the basic concept is two mics that are opposite polarity for room noise, while not for voice. You can source cheap mic capsules for a few $. Other possibilities might be a contact mic on the throat (really old school aircraft). IIRC there may be some trick mics that sit inside the inner ear and listen for voice that leaks into the ear drum from the Eustachian tubes or bone conduction. JR [/QUOTE]
