同时程序,使空气动力学和运动学的观察喉和胸壁系统被用来调查正常女性和男性的声音强度的变化。喉部的结果表明,当产生更高的强度水平时,最大流量下降率和喉气道阻力显着增加,开放商显着降低。呼吸结果表明,气管压力,百分比胸腔的贡献,肺容量,胸腔容积启动较高,肺和胸腔容积偏移较大时,更高的声音强度水平产生。喉和呼吸功能的结果表明,有些措施是不同的妇女比男子。平均数据支持通过吸入更高的肺和胸腔容积来实现气管压力增加的观点。个体受试者数据提供了用于改变声门气流波形形状的替代呼吸和喉部模式。
Simultaneous procedures for making aerodynamic and kinematic observations of the laryngeal and chest wall systems were used to investigate variations in vocal intensity in normal women and men. Laryngeal results indicate that significant increases of maximum flow declination rate and laryngeal airway resistance and significant decreases in open quotient occur when higher intensity levels are produced. Respiratory results indicate that tracheal pressure, percent rib cage contribution, lung volume, and rib cage volume initiations are higher, and lung and rib cage volume excursions are larger when higher vocal intensity levels are produced. Laryngeal and respiratory function results indicate that some measures are different for women than for men. Mean data support the notion that increases in tracheal pressure are achieved by inhaling to higher lung and rib cage volumes. Individual subject data provide alternative respiratory and laryngeal patterns for changing the shape of the glottal airflow waveform.
