What is the most common type of hearing loss in older adults?

Sensorineural hearing loss is the most prevalent type of hearing impairment found in older adults. This form of hearing loss arises from damage to the inner ear structures or the auditory nerve pathways leading to the brain. As individuals age, the sensory hair cells within the cochlea can become damaged or diminish in number, leading to reduced ability to hear high-frequency sounds primarily, which is a common experience among the elderly.

While the other options present valid types of hearing loss, they are less commonly seen in older adults. For example, otitis media is more frequently an issue in children; hereditary factors can contribute to hearing loss but are not as predominant as the age-related changes seen in the auditory system; and conductive hearing loss, which involves problems with the outer or middle ear that impede sound transmission, is not as frequent as sensorineural hearing loss in this demographic. Thus, recognizing sensorineural hearing loss as the most common type aligns with the observed trends in the aging population.
