Tinnitus is a dreadful physical condition in which people hear elusive voices regularly. It can be anything between buzzing, ringing, or other such irritating sounds. The U.S.Center for Disease Control estimates roughly about 15% of the general American public suffers from some kind of tinnitus. That’s quite a significant percentage indeed. While a 20 million suffer from terrible chronic tinnitus, another 2 million suffer from more pronounced or extreme tinnitus.
