Pseudoauditory Bone-Conduction Thresholds

Abstract

Fifty deaf children ranging in age from 5-14 years were divided into 2 "sensory-neural" groups: 38 partially deaf children and 12 totally deaf children. None of the subjects gave bone-conduction responses above 500 cps. In a third group of 20 partially deaf children with mixed hearing loss, air- and bone- conduction thresholds were similar, but the bone- conduction thresholds varied markedly in degree and extended beyond 500 cps. Thirty subjects were selected from the 3 groups to determine bone-conduction thresholds on 3 "non-auditory" areas of the body, with the non-auditory bone-conduction thresholds generally comparable or better than those obtained from the mastoid area.
