(HealthDay News) — Tinnitus is the sensation of a ringing, buzzing, clicking, roaring or hissing sound in one or both ears. It’s not a disease itself, but a sign that something is wrong with hearing, or the parts of the brain involved in processing sound.
The National Institute on Deafness and Other Communication Disorders says possible causes of tinnitus include:
- Hearing loss caused by exposure to loud noise.
- Having an sinus or ear infection.
- Having a cardiovascular problem.
- Having Menieré’s disease.
- Having an abnormality of the thyroid gland.
- In women, having had recent hormonal changes.
