About Deafness
• Deafness is usually the result of inner ear or nerve damage. 
It may be caused by a congenital defect, injury, disease, 
certain medication, exposure to loud noise or age-related 
wear and tear.
• The chief symptom is an inability to hear sound. For some, 
hearing may be possible with surgery or a hearing device. 
Lip-reading skills, written or printed text and sign language 
may help with communication.

Causes of Hearing 
Loss

Sensorineural Hearing Loss
• Sensorineural hearing loss is the most common form of 
hearing loss. It occurs when the inner ear, auditory nerve, 
or auditory structures in the brain are damaged. According 
to a 2017 article published in Gene Review, hearing loss, 
which occurs in early childhood, before a baby can speak, 
is sensorineural and usually genetic.
• Genetics, noise exposure, and more can also cause 
sensorineural hearing loss. Sensorineural hearing loss 
(SNHL) is the most common form of permanent hearing 
loss. SNHL results from damage to hair cells in the inner ear 
or the nerve pathways between the inner ear and the brain.

Conductive Hearing Loss
• conductive hearing loss happens when sounds cannot get 
through the outer and middle ear. It may be hard to hear soft 
sounds. Louder sounds may be muffled. Medicine or surgery can 
often fix this type of hearing loss.
• Types of conductive hearing loss include:
• Otosclerosis: This causes bone from the cochlea to grow onto the 
stapes bone in the middle ear, making it more difficult to hear.
• Cholesteatoma: This happens when tissue grows in the ear that 
shouldn’t be there. Sometimes it is present at birth. It can also 
appear following a chronic middle ear infection or due to a hole in 
the eardrum.

Mixed Hearing Loss
• Mixed hearing loss is a combination of conductive and sensorineural 
hearing loss. In this type of hearing loss, physical damage or 
blockage to the ear exacerbates genetic or age-related hearing loss. 
According to the American Speech-Language-Hearing Association, an 
example of combined hearing loss is “hearing loss because you avoid 
loud sounds and have fluid in your middle ear. The two together can 
make your hearing worse than if you had just one problem.
