What is tinnitus?
Tinnitus is when an individual hears a ringing, roaring, clicking, hissing, or buzzing in their ear. The noise heard can be at a high or a low pitch and may be unilateral or bilateral (heard in one or both ears).
Subjective tinnitus
Subjective tinnitus is when the noise can only be heard by the individual and accounts for 99% of tinnitus cases.
Objective tinnitus
Objective tinnitus is when the noise can be heard by others and the individual. The noises heard are produced by the body internally; conduction through body tissues delivers the noise from the source to the ears. Sources for objective tinnitus can be caused by blood flow or Musculo-skeletal movement.
