Abstract

This Letter presents an extension of a previous equation for the phonation threshold pressure by Titze [I. R. Titze, J. Acoust. Soc. Am. 83, 1536-1552 (1988)]. The extended equation contains the vocal-fold oscillation frequency as an explicit factor. It is derived from the mucosal wave model of the vocal folds by considering the general case of an arbitrary time delay for the mucosal wave to travel the glottal height. The results are illustrated with a numerical example, which shows good qualitative agreement with experimental measures.

摘要

本信函展示了对蒂茨（I. R. Titze，《美国声学学会杂志》83卷，1536 - 1552页，1988年）之前关于发声阈压方程的扩展。扩展后的方程将声带振荡频率作为一个明确的因素包含在内。它是通过考虑黏膜波在声门高度传播时任意时间延迟的一般情况，从声带的黏膜波模型推导出来的。通过一个数值示例对结果进行了说明，该示例与实验测量结果在定性上显示出良好的一致性。
