Abstract

Acoustic and Respiratory Measures as a Function of Age in the Male Voice

Violet O Cox and Mark Selent

The purpose of this study was to extend understanding of the effects of aging on the male voice by obtaining and analyzing both acoustic and respiratory measures across the aging continuum. Aerodynamic measurements such as vital capacity (VC), maximum phonation time (MPT) and the acoustic measurement Speaking Fundamental Frequency (SFF) are used commonly in Speech-language Pathology to aid in the assessment and treatment outcomes of vocal dysfunction. However, current research lacks analysis of the interaction across these parameters within males. This study examined the changes of these parameters and interactions in males across various age groups. Acoustic measures of SFF, MPT, and VC were obtained in age groups of 20-29, 30-39, 40-49, 50-59, and 60-69, N=35. Age and SFF were found to be statistically significant. No other statistically significant interactions were observed.
