Hearing Impairment and Tinnitus Pitch in Patients With Unilateral Tinnitus: Comparison of Sudden Hearing Loss and Chronic Tinnitus

Objectives The objectives were to analyze the results of pitch‐matching and loudness‐balance testing in patients with unilateral tinnitus and to evaluate the relationship between audiological findings based on the tinnitus‐affected and tinnitus‐unaffected threshold differences and tinnitus pitch by using linear interpolation methods. In addition, the effects of the duration of the tinnitus on this relationship were investigated. Sudden sensorineural hearing loss with tinnitus was selected for the “acute tinnitus” group, and unilateral tinnitus with unknown disease and a duration of more than 3 months was selected for the “chronic tinnitus” group.
