Tinnitus is the name given to the condition of noises ‘in the ears’ and/or ‘in the head’ with no external source. Tinnitus noises are described variously as ringing, whistling, buzzing and humming. The noise/s may be heard in one ear, both ears or in the middle of the head or it may be difficult to pinpoint its exact location. The noise may be low, medium or high-pitched. There may be a single noise or two or more components. The noise may be continuous or it may come and go. Experiences of tinnitus are very common in all age groups, especially following exposure to loud noise, however, it is unusual for it to be a major problem.
