Abstract
A communications headset system and method of use utilizing first and second headsets with integrated hearing protection for enabling users to wirelessly communicate when the hearing protection is engaged. Each headset is configured for placement onto a user'"'"'s head and includes hearing protection cups that engage a user'"'"'s ears and attenuate incoming sound waves external to the headset. The headsets include a first optical receiver that detects a light signal within a first receiving field-of-view and generates an incoming electrical signal corresponding to the light signal. A speaker converts the incoming electrical signal to an incoming audio signal, and then outputs the incoming audio signal as sound waves. A microphone converts outgoing sound waves to an outgoing electrical signal. An optical transmitter converts the outgoing electrical signal to one or more light signals and then broadcasts the one or more light signals within a broadcast field-of-view and a broadcast range.
