Analysis of voice of healthy aged persons with narrow band spectrum analyzer.
The purpose of this study is to measure the fundamental frequency (F0) and voice range of healthy aged persons. A total of 160 subjects without laryngeal or pulmonary complaints were involved in this study. The results were as follows. 1) F0: Results of the analysis indicated that the mean F0 of 70 to 74 years aged persons are higher than that of the other groups for male. There was, however, no significant difference among the groups for female. 2) Voice range: We found that the natural voice range for male decreases with increase of age, while the falsetto voice range increases. The natural voice range and falsetto voice range of females decrease with increase of age.
