扰动的基本音高和峰值振幅的声学信号与接触式麦克风系统进行了研究，为发展有用的措施，用于检测喉部病变的目的。研究了63例各种喉病变患者和31例正常人。在14例病例中，拍摄了喉部的高速电影，以检查引起声学信号扰动的生理机制。对收集的声学数据进行统计处理，并为每个受试者类别计算“临界椭圆”。讨论了“正常标准”概念的意义。有人指出，声扰动的生理机制是相当复杂的，许多生理方面可能必须考虑。强调了对病理性言语产生进行基础生理学研究的必要性。
Perturbations in the fundamental pitch and in the peak amplitude of the acoustic signal derived with a contact microphone system were investigated for the purpose of developing useful measures for the detection of laryngeal pathology. Sixty-three patients with various laryngeal pathologies and 31 normal subjects were studied. In 14 cases high speed motion pictures of the larynx were taken in order to examine the physiological mechanisms giving rise to the perturbations in the acoustic signal. The collected acoustic data were statistically processed, and a "critical ellipse" was computed for each subject category. The significance of the concept of a "normal standard" was discussed. It was pointed out that the physiological mechanisms for the acoustic perturbations were rather complicated and that many physiological aspects may have to be taken into account. The need for basic physiological research in relation to pathologic speech production was emphasized.
