Abstract

A voice communication unit is mounted with respect to a full face mask to allow the wearer of the mask to communicate with others. An optical transmitter positioned inside the mask responds to the user's voice to transmit an optical signal through the face lens of the mask. A receiver located outside the mask and optically coupled to the transmitter is responsive to the optical signal and generates a sound corresponding to the user's voice. A timer in the transmitter limits the operating period of the communication unit. The receiver includes volume control circuitry for maintaining the generated sound to a relatively constant level.
