Abstract : A system is described which provides a rigorously controlled milieu within which the testing of hearing and speaking functions underwater can be accomplished. Provisions are made for (1) the presentation and reception of acoustic stimuli, (2) the transmission of visual material for use either as multiple choice hearing test response items or as test material for studies of speech production and (3) the transmission of multiple choice responses by the subject to a digital (IBM) surface control unit. Research is currently in progress utilizing this unit (DICORS) in (1) the evaluation of normal hearing thresholds for pure tones and speech, (2) the evaluation of speech discrimination, (3) evaluating diver's capabilities to speak underwater, and (4) evaluating commercial underwater speech communications systems.
