Tinnitus is the hearing of sound when no external sound is present. It can take the form of ringing, hissing, buzzing, roaring, rushing, whistling or clicking. Sometimes, unclear voices or music are heard. Sounds may be soft or loud, low or high pitched, and may come from one ear or both.
Tinnitus is a chronic condition that develops gradually over time, most frequently caused by exposure to loud noises. According to the Mayo Clinic, tinnitus affects 20% of Americans, including about a third of people over age 55.
Severity can be slight to extreme, and may cause depression and anxiety, and interfere with sleep, concentration and normal daily activities. There are currently no effective medications to treat tinnitus--until TinniStop!
