ABSTRACT:
An underwater audio communication system to be worn by a diver is connected with and carried by a conventional face mask such that bone conduction occurs through the mastoid bone of the diver (i.e., behind the ear of the diver). The underwater audio communication system includes a face mask with a head strap for placement behind the head of the diver. A transceiver which is connected with and carried by the head strap is configured for receiving and transmitting ultrasonic signals in the water. At least one bone conduction transducer assembly is connected with and carried by the head strap at a location for placement against a mastoid bone of the diver. Each bone conduction transducer assembly is electrically connected with the transceiver.
