Types of Hearing Loss

	Conductive Hearing Loss  Caused by damage to the outer or middle ear, causing sound waves to be blocked as they move through the outer or middle ear. Can be as a result of middle ear infection, excessive wax, fluid in the middle ear, damage to the middle ear bones, a perforation or a foreign body in the ear.
	Sensori-neural Hearing Loss  Caused by damage to the inner ear The inner ear is unable to pick up the vibrations from the outer and middle ear or is unable to send the vibrations to the brain. Also called “nerve deafness” and usually occurs in both ears. Can be the result of aging, excessive noise, infection, certain drugs and birth defects.
	Mixed hearing loss  Caused by damage to the outer/middle ear and the inner ear. Typically, sound waves are not conducted efficiently to the inner ear, and once they reach the inner ear the vibrations cannot be picked up or sent to the brain.
