Elderly subjects with both peripheral and central auditory deficits perform less well with amplification than elderly subjects with peripheral deficits only. This decrease in aided performance remains after control for degree of sensitivity loss, absolute speech understanding score, and chronological age. Furthermore, females show greater central deficits and, consequently poorer aided performance, than males. We discuss the implications of these findings for the auditory rehabilitation of the elderly.
