Bone conduction communication system and method of operation

A method comprising:

• establishing a communicable link between a plurality of bone conduction communication systems each comprising a bone conduction transducer, each bone conduction communication system of the plurality of bone conduction communication systems associated with a distinct user;
• operating each of the bone conduction transducers in an input mode wherein the bone conduction transducers are configured to detect a vibration associated with a bone of the respective user;
• at a first bone conduction communication system of the plurality of bone conduction communication systems associated with a first user:
• detecting a vibration associated with a bone of the first user;
• converting the vibration to an audio signal;
• and
• transmitting the audio signal to the remaining bone conduction communication systems of the plurality of bone conduction communication systems;
• at a remainder of the bone conduction communication systems, excluding the first bone conduction communication system:
• receiving the audio signal;
• when the audio signal exceeds a threshold that depends on the first user, switching the bone conduction transducer associated with the respective bone conduction communication system to an output mode, wherein in the output mode the bone conduction transducer outputs the audio signal;
• and
• returning the bone conduction transducer to the input mode a predetermined time after the audio signal stops exceeding the threshold.
