Tinnitus


Tinnitus 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.

 
 
 
 
There are two kinds of tinnitus.

Subjective tinnitus is tinnitus only you can hear. This is the most common type of tinnitus. It can be caused by ear problems in your outer, middle or inner ear. It also can be caused by problems with the hearing (auditory) nerves or the part of your brain that interprets nerve signals as sound (auditory pathways).

Objective tinnitus is tinnitus your doctor can hear when he or she does an examination. This rare type of tinnitus may be

caused by a blood vessel problem, a middle ear bone condition or muscle contractions.
 
Another type of tinnitus is pulsatile tinnitus is the type of ear noise that is perceived as a rhythmic pulsing that is often in time with the heartbeat. It can be experienced as a thumping or whooshing sound. It is sometimes referred to as vascular tinnitus because in the majority of cases, it is related to disturbances in the blood flow.
