About Tinnitus

Over eight million people in the U.S. suffer from chronic ringing, hissing, buzzing or other noises in one or both ears, a condition known as tinnitus. Two million Americans are seriously debilitated by their tinnitus to the point that it severely impacts their quality of life. For most sufferers the cause of their tinnitus is unknown and there is currently no accepted therapy available. Physicians tell most tinnitus sufferers that there is no effective treatment for tinnitus so they must learn to live with it.
