Effects of physiological aging on vowel spectral noise. 1983

L A Ramig

Vowel spectral noise was studied in the sustained phonations of 48 men representing two levels of physiological condition (good and poor) within each of three chronological age groups (25 to 35, 45 to 55, and 65 to 75 years). Results indicated physiological condition was significantly correlated with noise rankings, whereas chronological age and noise were not significantly correlated. These findings support the notion that physiological condition is a significant variable to consider in the analysis of acoustic characteristics of voice.
