Hearing loss is a condition that causes partial or complete inability to hear sound and may affect one or both ears. Hearing loss can be conductive, sensorineural or mixed.

Conductive hearing loss is most commonly the result of sound being unable to pass through the outer ear and middle ear.

Sensorineural hearing loss is due to damage of the inner ear or auditory nerve.

Mixed hearing loss is a combination of both conductive and sensorineural hearing loss.
