Hearing loss causes

 

TYPES OF HEARING LOSS

Conductive Hearing Loss
This occurs when the external and middle ear can no longer conduct sound into the inner ear. One of the most common causes of conductive hearing loss is blockage in the external ear canal, typically caused by earwax buildup or infection. Most cases are temporary and can be corrected with proper medical treatment.


Sensorineural Hearing Loss
Often successfully treated with hearing aids, this type of hearing loss may result from:
• damage to the sensory cells or nerve fibers of the inner ear 
• exposure to diseases like mumps, meningitis, multiple sclerosis or acute Grave's Disease 
• use of certain drugs like aspirin, certain antibiotics
• low birth weight 
• genetics 
• head trauma 


Mixed Hearing Loss
This is a combination of conductive and sensorineural hearing loss. This type of loss may be successfully treated with a combination of medical assistance and use of a hearing aids.
