Lesson 14 : Sensory Impairment- Hearing

Sensori-neural Hearing Loss

When the inner ear does not properly process the sound vibrations, messages cannot be passed on normally to the brain. This is called sensorineural hearing loss. It can result from genetic defects, a severe infection such as mumps or meningitis, a head injury, certain medicines, an abnormal growth in the ear, aging or even from a very loud noise that damages the cochlea. This type of hearing loss usually cannot be reversed by medical or surgical means and is therefore permanent.
