Abstract : A theory that divers hear primarily by bone conduction has been proposed. The present status of this theory is reviewed, as well as past theoretical concepts and data from reported experiments. Experiments have focused on auditory sensitivity in the hyperbaric situation and in water as a function of basic response, depth, contents of the external ear and contents of the middle ear. Findings provide further support for the hypothesis that underwater sound energy is transduced to the cochlea by bone conduction rather than by normal external and middle ear linkage. Implications of this theory relative to divers' auditory functioning underwater are discussed. (Author Modified Abstract)
