Ringing in the ears (“tinnitus”) affects an estimated 10%-15% of the worldwide adult population.  This annoying condition, most commonly caused by exposure to loud noise, affects men more than women, especially as they get older.  The majority of those with tinnitus also suffer from some degree of hearing loss.  If so, the use of a hearing instrument can help by allowing the wearer to hear normal sounds more clearly, which helps divert attention away from the buzzing sounds.
