LXII Presbycusis Study of a Relatively Noise-Free Population in the Sudan

The purpose of this research was to study the hearing of a noisefree population in order to assess more accurately the effect of aging on hearing. One difficulty, among others, common to previous studies of hearing loss in aging is the exposure of their subjects to noises of modern civilization. Glorig and Nixon! stated: "Before we can really determine the threshold changes found in presbycusis we must measure hearing as a function of age in a population whose environment does not include the cacophony of modern civilization."
