Objective Our study used 1/24 octave pure tone test to find the maximum pitch of hearing loss

in order to learn the relations between the pitch of tinnitus and maximum pitch of hearing loss; to analyze the relationship between hearing and clinical characteristics in patients with tinnitus. Methods The research took 1/24 octave to find the maximum pitch of hearing loss and tinnitus pitch between normal pure-tone audiograms（PTA） test group and abnormal group. Results Our study detected 12 patients with hearing loss in 38 cases of normal PTA test. 127 cases were tested by 1/24 octave

the maximum hearing loss pitch was consistent with tinnitus pitch in 36 patients. The incidence of hypertension

sleep disorder and insufficient cerebral blood supply in the abnormal hearing group was higher than that in the normal. Conclusion The "targeting"of tinnitus therapy can be improved by 1/24 octave pure tone test.
