Explanation:
Detailed explanation-1: -Sensorineural deafness is a type of hearing loss. It occurs from damage to the inner ear, the place of origin of the nerve that runs from the ear to the brain (auditory nerve), or the brain.
Detailed explanation-2: -Damage to the cochlea typically causes permanent hearing loss. This is called sensorineural hearing loss (SNHL).
Detailed explanation-3: -SNHL happens when there is damage to tiny hair cells in the cochlear and/or the auditory nerve. Sound energy reaches the cochlea, but damaged hair cells are unable to convert sound waves into neural signals that pass through the auditory nerve to the brain. Auditory nerve abnormalities will also cause SNHL.
