March 20, 2008 Larynx microphones are ideal for transmitting voice electronically because your voice is directly transmitted from the larynx, with noise suppression of up to 10 dB - meaning they reduce ambient noise to close to zero. They’re used by special ops teams all over the world already, and now they’re available for a mobile phone so you can make calls in a noisy factory, or while jogging, skiing, cycling, and even riding a motorcycle or driving an open top car.
