The US Department of Defense allocated $ 10 million to conduct field tests of the Molar Mic, which looks like a bluetooth headset, though very unattractive.
The device consists of a mouthpiece with a waterproof microphone fitted to the teeth of a “specific” user. As soon as he starts talking, Molar Mic sends the audio signal to the radio transmitter fixed to the neck. Then the signal goes to the radio device of another user, after which it is already forwarded directly to the recipient.
The reception is somewhat more complicated. The mouthpiece converts the received sound signal into vibration to the teeth that pass through the jaw bone and the skull to the inner ear, where they transform into familiar sounds. Their peculiarity is that they are perceived as coming from the person's head, which, by the way, should be used for at least three weeks.
The military's interest in Molar Mic is explained by the fact that neither the raging element nor even the thunder of battle will prevent the use of such a device.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
