People without warning signs in whom tinnitus recently developed should call their doctor, as should people with pulsatile tinnitus. Most people with tinnitus and no warning signs have had tinnitus for a long time but should see their doctor about it if they have not already done so. In people with tinnitus, doctors first ask questions about the person's symptoms and medical history.
Doctors then do a physical examination. What they find during the history and physical examination may suggest a cause of the tinnitus and the tests that may need to be done see table Some Causes and Features of Tinnitus Some Causes and Features of Tinnitus Ringing in the ears tinnitus is noise originating in the ear rather than in the environment.
The nature of the tinnitus, including whether it is in one or both ears and whether it is constant or pulsatile. During the physical examination, doctors focus on examining the ears including hearing and the neurologic system.
They also listen with a stethoscope over and near the person's ear and on the neck for sounds of objective tinnitus. Most people should have a formal hearing test done by either the doctor or a hearing specialist audiologist. People with tinnitus in only one ear and hearing loss should have gadolinium-enhanced magnetic resonance imaging MRI.
People with pulsatile tinnitus often require magnetic resonance angiography MRA Magnetic resonance angiography MRA In magnetic resonance imaging MRI , a strong magnetic field and very high frequency radio waves are used to produce highly detailed images. MRI does not use x-rays and is usually very safe Attempts to identify and treat the disorder causing tinnitus are often unsuccessful. However, correcting any hearing loss for example, with a hearing aid Hearing Aids Many causes of hearing loss have no cure.
In these cases, treatment involves compensating for the hearing loss as much as possible.

Common Health Topics. Tests may include :. The most common cause of tinnitus is damage and loss of the tiny sensory hair cells in the cochlea of the inner ear.
This tends to happen as people age, and it can also result from prolonged exposure to excessively loud noise. Hearing loss may coincide with tinnitus. Research suggests that the sensory loss of certain sound frequencies leads to changes in how the brain processes sound.
As the brain receives less external stimuli around a specific frequency, it begins to adapt and change. If a foreign body or earwax causes tinnitus, removing the object or wax often makes the tinnitus go away. Tinnitus that sounds like a heartbeat may be more serious. It could be due to an abnormal growth in the region of the ear, such as a tumor or an abnormal connection between a vein and artery. One study found that out of teenagers, over half had experienced tinnitus in the previous year.
However, the investigators found that those who were prone to tinnitus tended to keep their music volume down, suggesting they may already have a hidden susceptibility to hearing loss in the future. They propose monitoring for tinnitus and a low tolerance for loud noise from an early age, as these could be early signs of future hearing loss. Tinnitus is a common problem in the general population, especially among those with certain risk factors.

Tinnitus often means there is damage to those hair cells, enough to keep them from sending electrical messages to the brain. These electrical messages is how the brain translates sound into something you can clearly comprehend like a car horn or person talking.
The current theory about tinnitus has to do with the silence or a lack of sound. To compensate, your brain fills that that lack of sound with the ringing or buzzing noise of tinnitus. The need for feedback from the ears does explain a few things related to tinnitus. For one, it tells you why that sound is a symptom of such a variety of illnesses that affect hearing from a mild ear infection to age-related hearing loss.
It also explains why the volume goes up at night for some people. Unless you are profoundly deaf, your ear picks up certain sounds all day long even if you do not realize it. The ears hear faint noises like music playing or the TV humming even if there is no comprehension of the sound.
At the very least, you hear your own voice, but at night, it all stops. Suddenly, all the sound disappears and the level of confusion in the brain rises in response. If you accept that tinnitus increases at night because there is no distracting noise to keep the brain busy, the answer is clear — create some. For some people suffering from tinnitus, all they need is a fan running in the background. Just the noise of the motor is enough to quiet the ringing.
There is also a device made to help those with tinnitus get to sleep.
