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 — 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. Treating an identified underlying cause sometimes helps. Other treatments reduce or mask the noise, making tinnitus less noticeable.
Tinnitus involves the annoying sensation of hearing sound when no external sound is present. Tinnitus symptoms include these types of phantom noises in your ears:
The phantom noise may vary in pitch from a low roar to a high squeal, and you may hear it in one or both ears. In some cases, the sound can be so loud it can interfere with your ability to concentrate or hear actual sound. Tinnitus may be present all the time, or it may come and go.
There are two kinds of tinnitus.
If you have tinnitus that bothers you, see your doctor.

A number of health conditions can cause or worsen tinnitus. In many cases, an exact cause is never found.
A common cause of tinnitus is inner ear cell damage. Tiny, delicate hairs in your inner ear move in relation to the pressure of sound waves. This triggers ear cells to release an electrical signal through a nerve from your ear (auditory nerve) to your brain. Your brain interprets these signals as sound. If the hairs inside your inner ear are bent or broken, they can “leak” random electrical impulses to your brain, causing tinnitus.
Other causes of tinnitus include other ear problems, chronic health conditions, and injuries or conditions that affect the nerves in your ear or the hearing center in your brain.
In many people, tinnitus is caused by one of these conditions:
Some causes of tinnitus are less common, including:
In rare cases, tinnitus is caused by a blood vessel disorder. This type of tinnitus is called pulsatile tinnitus. Causes include:
A number of medications may cause or worsen tinnitus. Generally, the higher the dose of these medications, the worse tinnitus becomes. Often the unwanted noise disappears when you stop using these drugs. Medications known to cause or worsen tinnitus include:
Anyone can experience tinnitus, but these factors may increase your risk:
Tinnitus can significantly affect quality of life. Although it affects people differently, if you have tinnitus, you also may experience:
Treating these linked conditions may not affect tinnitus directly, but it can help you feel better.
In many cases, tinnitus is the result of something that can’t be prevented. However, some precautions can help prevent certain kinds of tinnitus.
