Tinnitus Retraining Therapy Trial
In Brief
A Phase 3 clinical trial evaluating Conventional sound generator (SG), Placebo sound generator (placebo SG), and 2 other interventions for Subjective Tinnitus. Completed, enrolled 151 participants across 6 sites.
Detailed Summary
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.

Timeline
Interventions
Conventional SGs: Tranquil model sound generators (General Hearing Instruments, Inc.) are either inside or outside-the-ear devices that generate low-level noise, which is set at or just below the patient's mixing point (i.e., the noise level that just blends with the study participant's tinnitus)
Tranquil model placebo sound generators (General Hearing Instruments, Inc.) are either inside or outside-the-ear devices that generate a sound different from the active devices.
The standard of care treatment will be similar to that typically provided to patients with severe tinnitus at participating military medical centers and as described in the American Speech-Language-Hearing Association (ASHA) Preferred Practice Patterns in Audiology (ASHA, 2006). Tinnitus management will be based on the patient's complaints, history, audiologic evaluation, and self-assessment. The goal of the tinnitus management is to reduce negative cognitive, affective, physical, and behavioral reactions to tinnitus and to improve the patient's well-being and quality of life. Specific treatment recommendations will be individualized to reflect the participant's concerns and abilities, as well as his or her engagement in the decision-making process regarding treatment options.
Directive Counseling (DC): two-hour educational session during which the patient is given information regarding the nature of the tinnitus problem and related problems such as hearing loss and sound intolerance; visual aids to review the audiological/tinnitus/ hyperacusis evaluation, provide instruction on anatomy and physiology of hearing and tinnitus, introduce the Jastreboff neurophysiological model of tinnitus and related concepts of habituation, and describe and recommend the use of ST and environmental sound in the habituation process.
