 note = {Tinnitus is defined as the perception of various sounds or noises without any external stimuli, and it reflects a variety of pathological conditions involving the cochlea, auditory nerve and other structures related to hearing. Many patients with hearing loss, especially those with sensorineural hearing loss, complain of tinnitus. The pitch match test for tinnitus was applied to 200 ears in 151 patients, 74 males and 77 females. Presbyacusis in 23 ears, industrial hearing loss in 15 ears, idiopathic sensorineural hearing loss in 8 ears, and normal hearing with tinnitus in 48 ears were investigated. In the presbyacusis and the industrial hearing loss, hearing loss was occurred in the 4,000 Hz and 8,000 Hz, and pitch of the tinnitus belonged to the same range. In the idiopathic sensorineural hearing loss, there was not any tendency in the frequency of hearing loss and pitch. In the normal hearing ears with tinnitus, pitch was frequently noted at 8,000 Hz (pure tone).},
