Geriatric grand rounds: hearing impairment and functional independence.

Hearing loss is a commonly encountered impairment in the elderly. It can profoundly affect physical, psychosocial and cognitive function. In addition to the actual hearing loss, other factors contribute to the hearing handicap experienced by older persons. These include difficulty in understanding speech in noisy situations, difficulty in supplementing hearing with visual information, and the slowing of cognitive and psychologic processes. Many forms of amplification are available and can be very useful in reversing much of the functional impairment associated with hearing loss. A comprehensive audiological assessment should be recommended before selecting the type of hearing aid or assistive listening device. Such a referral also affords an opportunity for more extensive aural rehabilitation.
