Abstract: There is little question that changes in the ability to understand speech is a common complaint among elderly persons.Even without a corresponding loss of pure-tone sensitivity, older individuals often report difficulty with the understanding of speech.This deficit in speech understanding seems especially pronounced if the speech signal is degraded in some way.A large proportion of the studies that have investigated speech understanding in elderly persons have suffered from one or more methodological problems.Many earlier studies investigating the perception of speech by older individuals compared their abilities to those of a younger control group with differing peripheral auditory threshold sensitivity.Specifically, some investigators compared the speech recognition abilities of older persons with some degree of peripheral loss of auditory threshold sensitivity to the abilities of a younger group with no corresponding loss of sensitivity.Thus, it is difficult to separate the effects of aging on the perception of speech from the effects of hearing loss.Another common methodological error is not allowing for appropriate response time for subjects (Thompson, 1987).Reaction time has been virtually ignored in many studies of speech perception 1
