Objective:
To investigate the influence of age and gender on the parameters of voice, in order to make baseline data for the diagnosis and therapy of voice disorders.
Method:
One hundred and thirty two normal subjects were randomly selected in Shanghai, which were divided into two groups: one aged 18-40 and another aged 60-90. Each group included 33 male subjects and 33 female subjects. All subjects were assessed by VA (Tiger DRS. Inc), selected parameters including: F0, Jitter, Shimmer, NNE, CQ.
Result:
The factors of age and gender had the significant difference on voice, and there were interaction between age and gender. Sensitive parameters are F0, Jitter, NNE, CQ.
Conclusion:
There are some characteristic change of voice associated with aging. There is vast difference between aging male and aging female. Furthermore, aging voice can be improved by voice training.

Two-Way ANOVA
The two-way ANOVA analysis initially begins by stating the null hypothesis that there is an interaction effect between the two factors of a dataset. This effect can be visualized using line segments formed by joining the means for...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
