Age effect hearing levels for a black nonindustrial noise exposed population (ninep)

Abstract
A nonindustrial noise exposed population (NINEP) that describes the age effects for a black male and female population was established. The mean hearing threshold levels [HTL] for the black NINEP are significantly lower (better hearing) than the previously established mean HTL for a white NINEP when compared by sex. The availability of the black NINEP makes it possible to more accurately evaluate a typical industrial noise exposed population (INEP).
