Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary purpose of the Tinnitus Retraining Therapy Trial (TRTT) is to assess the efficacy of tinnitus retraining therapy (TRT) as a treatment for severe debilitating tinnitus. TRT is a non-medical intervention that uses directive counseling (DC) and sound therapy (ST)to habituate the patient's associated negative emotional reactions to tinnitus, its perception, and ultimately, its impact on the patient's life.
