Treatment of Tinnitus Using a Customized, Ultrasonic Acoustic Stimulus Delivered via the HyperSound Audio System

Tinnitus is a condition whereby sound is heard without external acoustic stimulus. It is often described as a constant tone (ringing), hissing, or roaring. Prevalence studies in western Europe and the USA have shown rates as high as 15% in the adult population (Baguley, McFerran, & Hall, 2013) with an estimated 20 million Americans that suffer from tinnitus. Researchers believe there are four primary effects of tinnitus on daily life, including (a) thought and emotions, (b) hearing, (c) sleep, and (d) concentration. It is a significant cause of diminished quality of life as well as depression, anxiety, insomnia, fatigue, and difficulty with concentration. To complicate further, each person is affected differently by tinnitus. The condition can occur from a variety of sources including disease and hearing damage, and can range in intensity from mildly annoying to completely debilitating (Claussen & Pandey, 2009).
