Effects of Aging on Selected Acoustic Voice Parameters: Preliminary Normative Data and Educational Implications

The study reported in this article attempted to obtain normative acoustic data of voice for elderly male and female speakers and to explore the educational implications of the effects of aging on those selected acoustic parameters. Voice samples from 21 male and 23 female elderly speakers aged 70 to 80 years were obtained on measures of 15 selected Multi-Dimensional Voice Program acoustic parameters. These data then were compared with the published norms for young and middle-aged adults. The results showed that, compared with young and middle-aged adults, elderly speakers had significantly different (usually poorer) vocal output on all of the selected acoustic parameters of voice. These findings illustrate the importance of establishing acoustic norms and thresholds for elderly men and women and stress the necessity of using discretion in making dragnostic measurements of elderly speakers' acoustic parameters of voice. This article also highlights the educational implications of such aging voice changes.
