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.
