Tinnitus involves central nervous system mechanisms and remains poorly understood

Evidence

Tinnitus is a percept of sound that is not related to an acoustic source outside the body. For many forms of tinnitus, mechanisms in the central nervous system are believed to play a role in the pathology. Despite its high prevalence of 5–10 %, relatively little is known about the neural mechanisms and causes of tinnitus. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2704
