本研究的目的是探讨声带内收对离体喉部模型语音质量的影响。前瞻性、重复测量实验。将10只切除的犬喉部安装在喉部切除发声系统上，记录了三个不同的声带内收水平。根据记录的辐射声历史计算了抖动、闪烁和信噪比（SNR）的声扰动测量值。离体实验表明，以声带内收为自变量，抖动均值（p=0.005）、闪烁均值（p=0.002）和信噪比均值（p=0.011）的增加具有统计学意义。理论结果表明，声门DC和AC分量随声门前音面积的增加而单调增加。声干扰随声带外展程度的增加而增加。离体喉部测量表明，高内收状态可能是声学上最好的。这可以从理论上解释为，随着前置区面积的增加，直流/交流比增加。
The purpose of this study was to investigate the effect of vocal fold adduction on voice quality in an ex vivo larynx model. Prospective, repeated-measures experiments. Ten excised canine larynges were mounted on an excised larynx phonation system and measurements were recorded for three different vocal fold adduction levels. Acoustic perturbation measurements of jitter, shimmer, and signal-to-noise ratio (SNR) were calculated from recorded radiated sound histories. Ex vivo experiments indicated that statistically significant increases in the means of jitter (p=0.005), shimmer (p=0.002), and SNR (p=0.011) measures decreased with respect to vocal fold adduction as the independent variable. Theoretical results showed that the DC and AC component of glottal area increased monotonically with prephonatory glottal area. Acoustic perturbation increased with the degree of vocal fold abduction. Ex vivo larynx measurements suggested that a hyperadducted state may be acoustically best. This may be explained theoretically by an increase in DC/AC ratio as the prephonatory area is increased.
