The development of a masking device for tinnitus patients

Abstract

Over 60 million Americans suffer from "ringing-in-the-ears" or tinnitus. This disorder ranges from mildly annoying to debilitating, and at the moment there is no known effective medical treatment. Acoustic masking of the subjective tinnitus sound does provide a measure a relief for many patients. A narrow band masking device that is tunable and potentially portable is described in this report.
