The cochlea is lined with tiny hair cells which, when stimulated by sound waves, send electrical signal to the brain that are then translated into sound. In the hearing impaired, these hair cells are damaged or destroyed, causing partial or total hearing loss. Trauma to the cochlea from loud noises or accidents can also cause hair cell damage. For many sufferers, the exact cause of their symptoms remains a mystery to health care professionals. Only when a specific factor is linked to the appearance or disappearance of the tinnitus can a cause be stated with certainty.
