What is Tinnitus?

Tinnitus is an abnormal perception of a sound reported by a patient but is unrelated to an external source of stimulation. Tinnitus is a very common disorder affecting over 50 million people in the United States. It may be intermittent, constant or fluctuant, mild or severe, and may vary from a low roaring sensation to a high pitched type of sound. It may or may not be associated with a hearing loss. It is also classified further into subjective tinnitus (a noise perceived by the patient alone) or objective (a noise perceived by the patient as well as by another listener). Subjective tinnitus is common; however, objective tinnitus is relatively uncommon. The location of tinnitus may be in the ear(s) and/or in the head.
