What is Tinnitus?
Tinnitus is the perception of sound in the ears or head not caused by an external sound source. Ringing and buzzing sounds may be heard in one or both ears or appear to be generally in the head region but can be variable and difficult to decide exactly where it seems to be.
Almost always, it is a totally subjective noise which only the person who has it can hear. On rare occasions, it can be heard by others as well; this is called objective tinnitus but is not associated with the effects of noise exposure.
Tinnitus is not an illness or a disease in itself, but it is often a symptom of a problem with the ear or the hearing pathways to the brain. Usually, it occurs when the inner ear is damaged or impaired in some way. Some of the causes of are:
- Exposure to loud noises
- Ear infections
- Head injury
- Waxy build-up in the ear
These are just a few of the most common causes, but it can also be a side-effect of medication or a result of other health concerns, such as high blood pressure. It is also commonly associated with age-related hearing loss, although it can affect anyone at any age.
