From Wikipedia, the free encyclopedia. Presbycusis (also spelled presbyacusis, from Greek presbys “elder” + akousis “hearing”), or age-related hearing loss, is the cumulative effect of aging on hearing. It is a progressive bilateral symmetrical age-related sensorineural hearing loss.

Factors that can cause hearing loss, which can be difficult to distinguish or separate from presbycusis, include: 1  Heredity: Factors like early aging of the cochlea and susceptibility of the cochlea for drug insults are genetically determined.

Figure 2. Neural Presbycusis. Neural presbycusis is characterized as a degeneration of neurons and results in hearing loss similar to sensory presbycusis. However, speech understanding is far worse than would be anticipated from the audiogram, in this example, perhaps only 40% to 60% in each ear.

There are four pathological types of presbycusis: 1  Sensory: characterised by degeneration of organ of corti. 2  Neural: characterised by degeneration of cells of spiral ganglion. 3  Strial/metabolic: characterised by atrophy of stria vascularis in all turns of cochlea.

The hearing loss is most marked at higher frequencies. Hearing loss that accumulates with age but is caused by factors other than normal aging is not presbycusis, although differentiating the individual effects of multiple causes of hearing loss can be difficult.

The third type described by Schuknecht is metabolic presbycusis and “is due to defects in the physical and chemical processes by which energy is produced and made available for use by the sense organs” (p. 375) with degeneration of the stria vascularis as the cause.

Simply put, presbycusis is sensorineural hearing loss that occurs as you age. This type of hearing loss usually happens gradually over the span of many years, affects both ears simultaneously (bilateral hearing loss), and occurs due to age-related changes within the inner ear and along the nerve pathways to the brain.

The fourth type of hearing loss associated with aging is mechanical presbycusis that Schuknecht later termed cochlear conductive presbycusis.1 He ascribed it to an unfavorable alteration of basilar membrane micromechanics that affects the membrane’s motion.
