Question

Which type of hearing loss will result in the acoustic reflex being absent or elevated?

		Conductive Hearing Loss
		Mixed Hearing Loss
		Sensorineural hearing loss
		Retrocochlear hearing loss

Answer 1

Conductive hearing loss

Conductive hearing loss is due to the impairement in the transfering of sound waves through outer ear, tympanic membrane and middle ear.

acoustic reflex is an involuntary muscle action which occur in the middle ear when loud sound stimuli occur.

Sensorineural hearing loss is the hearing impairment occur due to the damage in the inner ear or in the nerves which connect the ear and the brain.

Retrocochlear hearing loss is another type of hearing loss that occur in the inner ear or auditory nerve due to cochlear damage.

Mixed Hearing Loss is the combination of conductive hearing loss and sensorineural hearing loss which affect both middle and inner ear.
