What is the three-part classification of hearing loss?

The three-part classification of hearing loss includes conductive, sensorineural, and mixed types.

Conductive hearing loss occurs when sound is not conducted efficiently through the outer ear canal to the eardrum and the tiny bones of the middle ear. This can result from obstructions, infections, or damage to the ear structures.

Sensorineural hearing loss is due to problems within the inner ear or the auditory nerve pathways to the brain. This type includes issues stemming from hair cell damage in the cochlea or from neural deficits.

Mixed hearing loss is a combination of both conductive and sensorineural loss, indicating that there is both a problem in the outer or middle ear as well as in the inner ear or auditory nerve.

Understanding these classifications is essential for audiologists and health technicians as it guides diagnosis, management, and treatment options for individuals experiencing hearing loss.
