Understanding Hearing Loss....
Hearing losses occur in many types and degrees. The solution for the hearing loss depends heavily on what type of hearing loss you have and to what extent your hearing has been affected. In general there are three main types of hearing loss.
Conductive Hearing Loss
This is caused by problems in the outer and/or middle ear, that can stop sounds getting through to the innerear. In children, this is mostly due to middle ear infections. Most infections heal without causing any lasting damage with medication. But sometimes they can cause temporary hearing loss. If the infections last a long time, the middle ear can be damaged, which can result in permanent hearing loss.
Sensorineural hearing loss (SNHL)
This happens when some of the delicate hair cells in the inner ear break down, and are unable to convert sound waves into electrical signals. Sometimes the nerve pathways in the auditory nerve get damaged, which also prevents the signals from reaching the brain. This kind of hearing loss can also be caused by excessive noise from machinery, or loud music. Unfortunately this type of hearing loss cannot be rectified with medication.
Mixed Hearing Loss
Mixed hearing loss is a combination of Conductive and Sensorineural hearing loss. The problem is in the outer and/or middle ear and inner ear. Although the problem in the outer ear and middle ear is rectified by means of medication or surgery, the deficit in the inner ear will still remain.
