摘要
本文介绍了一种测量装置,它能够测量 15.2 mm × 30.4 mm 面积上的小尺度压力分布,采样率高达 1.2 kHz。它被用于研究发音时声带的接触压力。这是在 11 头猪喉部的体外实验中进行的。在不同的伸展水平和气流速率下,测量了声带内侧表面的接触压力和其他发音参数,如声门阻力和声带闭合速度。结果进行了统计分析。结果表明,当操作声带或增加流速时,接触压力会升高。
What kind of phonation causes the strongest vocal fold collision? - A hemi-larynx phonation contact pressure study.
This paper presents a measurement setup which is able to measure the distribution of small scale pressure on an area of 15.2 mm × 30.4 mm with a sample rate up to 1.2 kHz. It was used to investigate the contact pressures of vocal folds during phonation. This was performed in ex vivo experiments of 11 porcine larynges. The contact pressure at the medial surface and other phonation parameters, as the glottal resistance and the closing velocity of the vocal fold, were measured at different adduction and elongation levels and air flow rates. A statistical analysis was carried out. It could be shown that the contact pressure rises, when the vocal fold is manipulated or when the flow rate is increased.
