Causes of Deafness
Loss of hearing doesn't just happen when you're born. There are lots of other ways. Meningitis--what in the world does that mean? A common hearing loss is presbycusis. What? Who made up these words?Some hearing loss causes are diseases. The main disease is ottis media, which is an infection to the middle ear bone. It usually happens in early childhood. Meningitis, or a high fever, can cause damage to the inner ear.
Birth defects that occur during pregnancy may cause hearing loss. If a pregnant woman has the German Measles it can cause a hearing loss in her unborn child. A blood substance in unborn children called the Rh Factor can also cause hearing loss.
Environmental factors can cause hearing loss. Tinnitus is a disease that occurs when a person is exposed to consistent loud noises . An explosion or gunshot can gradually give you permanent hearing loss. If you work in a large factory with loud machinery that makes lots of noise can cause Tinnitus.
Hearing loss can be caused by a high fever. That is called meningitis which can damage the inner ear plus damage the auditory system.
Aging is also a common cause for hearing loss. Two thirds of people over 65 years of age in the United States get a kind of hearing loss called presbycusis. Some scientists think that aging may also cause changes in the auditory system or in the brain that reduce hearing ability.
