Abstract : Studies completed were: Diver-to-surface communication (near field and over distance); diver-to-diver communication; speech modification in helium at 300 feet; off-line evaluation of the RELA unscrambler; underwater microphone evaluation; diver auditory acuity; minimum audible angle of scuba divers. Studies nearing completion: Speech intellibility in neon at depths of 300-680 feet; speech feedback (divers underwater hear their own speech immediately after their utterances and attempt modification for better intelligibility).
