For the Norwegian radio show, see Tinitus (radio show). Tinnitus is the hearing of sound when no external sound is present. While often described as a ringing, it may also sound like a clicking, hiss or roaring. Rarely, unclear voices or music are heard. The sound may be soft or loud, low pitched or high pitched and appear to be coming from one ear or both.
For many, it's a ringing sound, while for others, it's whistling, buzzing, chirping, hissing, humming, roaring, or even shrieking. (To get an idea of what people with tinnitus hear, go to www.ata.org/sounds-of-tinnitus .) The sound may seem to come from one ear or both, from inside the head, or from a distance.
