The present work examined the predictive nature of modeled velopharyngeal orifice area calculations obtained using the hydrokinetic equation (Warren and DuBois, 1964) during conditions simulating voiceless fricative production. Results indicated that accurate estimates of velopharyngeal orifice area can be obtained during aerodynamic events like those known to exist during fricative production. These findings were interpreted to lend support to the view that aerodynamic assessment incorporating hydrokinetic principles provides a useful, noninvasive method for clinical testing and research investigation of velopharyngeal function.
本研究考察了在模拟清擦音发声条件下，使用流体动力学方程（Warren和DuBois，1964）获得的腭咽口面积计算模型的预测特性。结果表明，在诸如擦音发声时已知存在的空气动力学事件期间，可以获得腭咽口面积的准确估计值。这些发现被解释为支持这样一种观点，即结合流体动力学原理的空气动力学评估为腭咽功能的临床测试和研究调查提供了一种有用的、非侵入性的方法。
