title: [Factors influencing the pitch and loudness of tinnitus].
abstract: Pitch match and loudness balance tests were given to 397 cases with tinnitus. The factors which influenced tinnitus pitch and loudness were analyzed statistically from the clinical point of view. The results obtained were as follows: 1) Onomatopoeia of tinnitus, either [Keeeen] or [Jeeeen], were observed in a majority of cases. 2) Significantly sharp sounding onomatopoeia such as [Keeeen] or [Meeeen] had high pitches, over 4kHz, and dull sounds like [Gooooh] or [Buuuun] had low pitches, below 500Hz. 3) Acute stage tinnitus, within one month of onset, had a significantly depressed pitch and walked loudness, above 6dB. 4) The pitches observed in cases with Meniere's disease and chronic otitis media were distributed evenly from low frequencies to high. In other cases, especially presbyacusis and noise deafness, high pitch tinnitus (above 4kHz) was frequently noted. The loudness of tinnitus without hearing loss was significantly greater than in other diseases. 5) As a rule the more deteriorated the hearing level was, the lower the frequency of the pitch, and the smaller the loudness in tinnitus. 6) A high pitch of tinnitus nearly corresponded with hearing type, that is, the pitch of tinnitus was also in accordance with the disturbed frequency in the hearing threshold.
