ABSTRACT
Objective To study the variable orderliness of vocal fold vibration caused by the voice with different frequency in chest register of various healthy subjects having several age and sex through electroglottographic examination.Methods 120 healthy subjects were respectively evaluated with electroglottography, including the old group, the adult group, the men group and the female group. Meanwhile the parameters of vocal fold vibration, such as the contact quotient, the contact index, the contact quotient perturbation and the contact index perturbation were measured and analyzed.Results With increase of the frequency, the contact quotient was decreased in all subjects, having signification difference. The contact quotient of old group and adult group ,men and female group had also signification difference. But other parameters not represented the difference in statistics.Conclusion The closer degree of vocal fold was varied with the different frequency in chest register voice from the healthy subjects who were different in age and sex ,but the symmetry and regulation of vocal fold vibration were not related to age and sex. The results were help to study physiology of vocal fold.
