Abstract Tinnitus is the perception of sound without a corresponding external sound source. This condition affects approximately 14% of adults, with approximately 2% experiencing severe symptoms. Underlying mechanisms of tinnitus suggest involvement of both peripheral and central processes, in which cochlear injury and deafferentation may trigger maladaptive plasticity, increased central gain, and thalamocortical dysrhythmia, modulated by limbic and salience networks.

Abstract Tinnitus is defined as the conscious awareness of a tonal or composite noise in the absence of a corresponding external acoustic source. This international multicentre, parallel-arm, superiority, randomised controlled trial investigated whether combination therapies are superior to single interventions in the treatment of chronic subjective tinnitus.
