Sixteen normal ears and 231 ears with sensorineural deafness were studied by forward and reverse sweep continuous-tone Bekesy audiometry. In normal ears, the tracings overlapped and this was also generally true in clinical material for cochlear deafness with loudness recruitment and slight-tone (less than 30 db) decay. Abnormal tracings were seen more frequently in cases with lesions in the brain-base area including the auditory nerve and cerebellum. Poor reverse tracings were associated with a part of the cases with abnormally high-tone decay and incomplete or absent loudness recruitment.
