By and large, with the development of technology, two-way communication systems like walkie-talkies have not changed much. Yes, they became smaller, their radius of action increased, but something fundamentally new did not appear. And now it became known that the US Department of Defense has signed a contract for the implementation of a communication system, in which elements will use bone conduction to transmit sound. Meet: Molar Mic.
Molar translated from English is the common name for the sixth, seventh and eighth teeth of the human jaw. And it's not just that. The fact is that the Molar Mic system is just the same designed to be attached to the teeth. And bone conduction in this case will provide a hidden two-way communication even at a high noise level or if the system wearer needs to be as quiet as possible. Each Molar Mic will be tailor-made for a specific person, and once secured to the surface of the tooth, the tooth and jaw will conduct sound vibrations directly into the inner ear. Some modern smartphones and headphones can offer something similar, with the only difference that the speaker and microphone are located, so to speak, “outside the body”. While the Molar Mic is located inside the mouth.
Using this method virtually eliminates the possibility of eavesdropping on what is being said “on the other end of the line”. And also allows you to negotiate, perfectly hearing the surrounding sounds. The waterproof microphone built into the system, according to the authors of the development in the person of Sonitus Technologies, registers even a quiet whisper with a sufficiently loud external noise. In addition to the speaker and microphone, the Molar Mic device includes the Tactical Neckloop, which uses Near-field magnetic induction communication to communicate with the device using a magnetic field. Also, the developers say that the first tests of the Molar Mic system were very successful. It was used, for example, during the rescue of victims of Hurricane Harvey last year.
