Detailed explanation-1: -Age-related hearing loss, also called presbycusis, comes on gradually as a person grows older. It seems to run in families and may occur because of changes in the inner ear and auditory nerve, which relays signals from the ear to the brain.

Detailed explanation-2: -Presbycusis is a true sensorineural loss, in which both cochlear hair cells and, to a lesser extent, the spiral ganglion cells in the vestibulocochlear nerve can be affected [2, 28-30]. (See “Evaluation of hearing loss in adults” and “Evaluation of hearing loss in adults", section on ‘Classification of hearing loss’.)

Detailed explanation-3: -It is evident that the previously advanced concept of four predominant pathologic types of presbycusis is valid, these being sensory, neural, strial, and cochlear conductive.

Detailed explanation-4: -What causes age-related hearing loss? Most commonly, presbycusis (age-related hearing loss) comes from changes in the inner ear that occur as you age. It typically affects both ears equally and has a gradual onset. Many people have a combination of age-related hearing loss and noise-induced hearing loss.
