Tinnitus is the medical term for hearing noises in your ears when there is no outside source of the sounds. Tinnitus is often called ringing in the ears, but it may also sound like blowing, roaring, buzzing, hissing, humming, whistling, or sizzling. The noises you hear can be soft or loud. You may even think you are hearing air escaping, water running, the inside of a seashell, or musical notes.
Head noise (tinnitus) can be caused by broken or damaged hairs on auditory cells, turbulence in a carotid artery or jugular vein, temporomandibular joint (TMJ) issues, and problems in the auditory processing pathways of the brain. Tinnitus (TIN-ih-tus) is the perception of noise or ringing in the ears. A common problem, tinnitus affects about 1 in 5 people. Tinnitus isn't a condition itself â it's a symptom of an underlying condition, such as age-related hearing loss, ear injury or a circulatory system disorder. Although bothersome, tinnitus usually isn't a sign of something serious. Although it can worsen with age, for many people, tinnitus can improve with treatment.
