Dive Helmet Communication System

Oceanit proposes to create technologies to improve diver communications at working depths compensating for different gas densities and minimizing communication feedback. The goal is to investigate applications of digital signal processing and actuators (speakers and microphones) and apply these findings in developing a Helmeted Diver communication system(s). This development is to address diver helmet communications that will operate well with diver helmet breathing noise and underwater tool noise while operating in varying gas density/mixtures (squeaky voice). The developed system (helmet (bottom-side) and diver station (topside)) must demonstrate improved and clear communications in actual dives and/or dive chambers. The components must be rugged and usable in marine environments while utilizing existing umbilical lines. It would include noise monitoring and consider future fiber optic signal umbilical lines.
