Types Of Hearing Loss

Conductive Hearing Loss

This involves the breakdown or obstruction of some part of the external or middle ear. The physical vibrations of sound are no longer transmitted or conducted through air, most problems are medically correctable. Some causes of a conductive loss can be cerumen blockage, infection of the outer ear, perforation of the tympanic membrane, otitis media, genetics, otosclerosis, head injury and ear surgery.

Sensorineural Hearing Loss

This kind of hearing loss is a result of damage to the inner ear hair cells in the cochlea and or damage to the neural pathways of the auditory nerve. Some of the causes of this hearing loss can be presbycusis, hereditary, meniers disease, noise induced, acoustic neuroma, infection, ototoxic medication, trauma, surgery or disease.

Mixed Hearing Loss

This is a combination of more than one type of loss usually conductive and sensorineural. Some of the causes of this hearing loss can be illness, ototoxic medication, hereditary, trauma, malformation of the ear, cerumen, fluid in the ear, ear infections and perforation of tympanic membrane.

Non Organic Hearing Loss

This is often called a functional loss, and is a result of some sort of psychological cause and there is nothing physically wrong with a person’s hearing mechanism.
