A hundred and three ears with tinnitus were examined neurotologically and tinnitus matching tests were carefully carried out using tinnitus sythesizer (Norwest Acoustics SG-1). Then the residual inhibition (RI) was checked with one minute masking test of Vernon.RI was detected in 67% of the ears with tinnitus, and their durations were widely distributed from 3 seconds to over 2 hours, although 78% of them were within 1 minute.No correlation was observed between the “loudness of tinnitus” and the RI duration, nor between the hearing level at the tinnitus frequency and the RI duration.Mean age of the RI positive patients was 54.0 years, which was considerably higher than that of RI negative patients (47.2 years).The great majority of the RI positive patients had high frequency (>2kHz) tonal tinnitus.Further additional work seemed to be necessary to make the RI test one of the standard tests of tinnitus.
