Clinical studies of hearing acuity in high frequencies on tinnitus without hearing loss

Abstract

The examination of the high frequency range of the cases of tinnitus without hearing loss was done by using the tinnitus audiometer. The average age was 33 years old. It was the same as the usual report by the record of the tinnitus inspection. Dip which wasn't recognized in the pure tone audiometry was recognized in 2 example during the cases of tinnitus without hearing loss 10 example. The average of the measurement result of the high range of the cases of tinnitus without hearing loss and standard deviation were 20.7dB±12.7 with 10kHz and 28.7dB±16.7 with 12kHz. There was an example which rise in the theshold of the high range was estimated at in the cases of tinnitus without hearing loss, and the possibility that it was one factor of the tinnitus was suggested.
