Bone Mic  
In a bone-conductive microphone, the vibrations from our bones are transmitted through our skin. The microphone converts the skin vibrations into an analog electrical signal, which is then sampled by an analog-to-digital converter. The bone microphone only produces signals when the user talks; environment noise or background speech will not affect the bone microphone.

 
PTT  Push to Talk - The act of pressing a transmitting switch or button on a radio (vhf or uhf) to activate a voice communication between the radios.
