Is tinnitus permanent?

Acute tinnitus can last from a few minutes to a few weeks after noise exposure.24 In some cases, tinnitus has a gradual onset and several years can pass before an intermittent, low-intensity tinnitus becomes bothersome.25 Spontaneous remission by natural habituation is experienced by more than three-quarters of sufferers. Habituation occurs within the CNS, whereas adaptation involves a peripheral sensory organ.8 For those in whom the condition worsens, the tinnitus intensity increases over time but its pitch tends to remain stable.22 If tinnitus persists for more than 2 years, it is considered permanent and irreversible.26.
