If you start experiencing tinnitus, try to remember any unusual thing that happened with your ear. It could be exposure to loud noise which can cause the ear to vibrate and hum. Concerts and musical events can lead to tinnitus. The loud sound damages the tiny hair inside our ear cochlea. The job of these hair is to send signals to auditory nerves when they detect some form of sound. However, since they get damaged by loud noise, they send the wrong signals and the nerves detect a signal even when everything is quite. Thus the humming in your ear at all times.
Examine your ear for any deposition of wax. Deposition of earwax is a natural process and it protects your ear canal by trapping up the dirt that enters and also reducing infection. However, a more than needed accumulation can cause irritation in the canal and lead to tinnitus. This examination can be done by yourself at home or by a doctor at the hospital.
At times, tinnitus can be a result of changes in ear bone. These changes could be in the genes and carry on in the family. The abnormal bone shape causes disturbance in the ear canal and produces a humming. However, bone examinations can only be carried out by a doctor. Doctors who specialize in hearing problems are known as audiologists and will not only determine the cause but will also help you cure it.
The doctors will also test for the diseases of which tinnitus is a usual symptom. These tests will include blood tests, CT and even MRI scans. Audio metric tests are held to judge the nature and severity of the tinnitus.
