Treatment for hyperacusis can broadly be categorized into those which target the physical symptoms, and those which aim to reduce the psychological burden of the condition. Tinnitus retraining therapy (TRT) involves educating the patient about their condition alongside gradual sound enrichment, and its use in hyperacusis is becoming increasingly popular.[26] Prolonged low-level noise exposure has been shown to have a reversing effect on the enhanced neural gain, which is thought to be the underlying mechanism of hyperacusis.[28]
