Summary

The purpose of this multi-site randomized clinical study was to assess treatment outcomes for three forms of tinnitus treatment: Tinnitus Retraining Therapy (TRT), Tinnitus Masking, and Tinnitus Education (TED). There were four study sites: VAMC Audiology Clinics at Bay Pines, FL; Portland, OR; Seattle, WA; and San Diego, CA. Thirty-six subjects (Veterans) were enrolled into treatment at each site - 12 into each treatment group. Each subject received 18 months of treatment. Treatment appointments and outcome questionnaires occurred at 0, 3, 6, 12, and 18 months. Qualified subjects were initially randomized to one of the treatment groups or to a 6-month Waiting List group. Those in the Waiting List group completed outcome questionnaires at 3 and 6 months, and were randomized into one of the three treatment groups. They then received 18 months of treatment as above.

Interventions

PROCEDURE

Tinnitus Masking

Sound therapy with Tinnitus Masking is intended to produce immediate relief from the discomfort caused by tinnitus (Vernon, 1977; 1987; Vernon, 1988). If maskers or combination units are used, the masking sound can be set at any level the patient chooses to attain maximum relief. Relief using masking noise can be accomplished using the external sound of the masker, which is generally a more acceptable sound than the tinnitus.

PROCEDURE

Tinnitus Retraining Therapy (TRT)

The TRT procedure adheres as closely as possible to the methodology described by Dr. Pawel Jastreboff. For TRT, sound therapy is used to facilitate long-term habituation to tinnitus (Jastreboff, 1999b).

PROCEDURE

Tinnitus Education (TED)

TED represents tinnitus treatment that would typically be provided by audiologists using hearing aids and counseling (although for this study the counseling has been structured and expanded to be equivalent in length to the other two groups).
