Intervention for Reduced Sound Tolerance

To assess the efficacy of TRT-based intervention for hyperacusis in hearing-aid eligible persons.

  1. Tinnitus Talk
    Hyperacusis is the intolerance to sound levels that normally are judged acceptably loud to others. The presence of hyperacusis (diagnosed or undiagnosed) can be an important reason why some persons reject amplified sound from hearing aids. Tinnitus Retraining Therapy (TRT), originally proposed for the treatment of persons with debilitating tinnitus, offers the significant secondary benefit of increased Loudness Discomfort Levels (LDLs), along with expansion of the dynamic range for loudness. TRT uses both counseling and sound therapy from daily exposure to soft sound from bilateral noise generator devices (NGs) and has been promoted as an intervention for hyperacusis. The hypothesis of this investigational study is that the counseling and sound therapy principles used in TRT can be applied successfully to treat hearing-impaired hearing-aid candidates with reduced sound tolerance who are otherwise should benefit from hearing aids.
