What's the history of hearing loss, or hearing impairment with age?

Gradual HF loss: Many people will experience gradual bilateral high frequency loss with age. In some the loss will become severe enough that it interferes with ability to discriminate voices or hear in general. Some hearing loss is clearly attributable to noise exposure, but some is likely genetic as well.

Presbyacusis: Aging can cause progressive hearing loss in higher frequencies called sensorineural deafness. Not everyone gets this kind of heating loss even when they are aged.

Presbycussis: In western society, there is a well known group of diseases called presbycussis, which is the term used for the hearing loss of aging. Although genetics and noise play an important role, over the age of about 60, there is a gradual degeneration of inner ear hair cells and a progressive loss of hearing in the high pitches. Sometimes, a hearing aid or aids may help.
