What is tinnitus?

Tinnitus is a generic term used to describe a ringing or noise in the ears that occurs in the absence of external sound. This is a very common condition that is thought to occur in up to 15% of people. It can occur in one or both ears, and often people will describe the sound as “coming from their head.” There are a variety of descriptions that people use for their tinnitus such as whooshing, ringing, pulsing, and/or buzzing, and the quality of the sound varies by individual.

Symptoms of tinnitus can cause great distress

While tinnitus can be caused by conditions that require medical attention, it is often a condition that is not medically serious. However, the distress and anxiety it produces can often disrupt people’s lives. Because of the negative impact tinnitus can have on people, it may be helpful to learn more information on what symptoms are common and benign (not serious), and those that require medical attention and interventions.

What causes tinnitus?

Tinnitus can be broken down into two major types: pulsatile and non-pulsatile.

Pulsatile tinnitus is a noise in the ear that sounds like a heartbeat. Often people will describe a perception of a pulsing in their head and the ability to hear their heartbeat. Tinnitus that sounds like someone’s heartbeat can be caused by normal or abnormal blood flow in the vessels near the ear. This type of tinnitus should be brought to the attention of your physician, because there are various rare conditions that cause it that may require medical intervention.

Non-pulsatile tinnitus is more common, but it can be more difficult to identify a cause. Most often tinnitus is associated with a hearing loss. However, people can have tinnitus with normal hearing. While people with tinnitus often believe the problem is with their ears, there is some evidence in tinnitus research that suggests the noise originates in the brain, even though it is perceived through the ears.

There are some specific conditions of the ear or brain that are associated with tinnitus. It is common for many of these conditions to have other symptoms associated with them, such as hearing loss or imbalance.

Despite the list of possible causes of tinnitus, often times there may be no identifiable causes, and doctors generically say that a patient has tinnitus. Even if a source of the tinnitus is identified, most tinnitus is due to benign, or non-threatening, conditions.

Note: This list is not intended to be comprehensive, but to provide representative examples of things that may cause tinnitus.
