Sound Therapy for Tinnitus: Options for Audiologists

Abstract

Purpose: Sound therapy to reduce the emotional and functional effects of tinnitus has been used by audiologists since the 1970s when Jack Vernon introduced the masking method to provide a sense of relief from tinnitus distress. Our group renamed masking sound as "soothing" sound and distinguished it from "interesting" and "background" sound, each of which has a different purpose for tinnitus sound therapy. Other methods of sound therapy have the potential to reduce the "sensation" of tinnitus, including notched noise, matched noise, desynchronization, and residual inhibition. The purpose of this article is to provide an overview of the different sound therapy approaches to serve as a resource for audiologists who often provide sound therapy to their patients with tinnitus. Conclusion: Although, according to systematic reviews, sound therapy does not have strong evidence for treatment of tinnitus, it is nonetheless well evidenced both through abundant research and clinical utilization mostly by audiologists. It is unknown if any one form of sound therapy is superior to any other.
