采用已建立的胸壁运动学观察（Hoit & Hixon，1987）和压力-流量观察（Smitheran & Hixon，1981）程序，研究10名健康年轻人在耳语和说话时的呼吸和喉功能。结果表明，耳语涉及一般较低的肺容量，较低的气管压力，较高的translaryngeal流量，较低的喉气道阻力，和较少的音节每呼吸组相比，说话。在耳语期间使用较低的肺容量而不是说话可能反映了实现不同的气管压力目标的手段。每个呼吸组产生的音节数量的减少可能是对与说话相比伴随耳语的高空气消耗率的调整。在这项调查中研究的正常受试者的性能并不类似于个人的言语和语音障碍的特点是低电阻负载。
Established procedures for making chest wall kinematic observations (Hoit & Hixon, 1987) and pressure-flow observations (Smitheran & Hixon, 1981) were used to study respiratory and laryngeal function during whispering and speaking in 10 healthy young adults. Results indicate that whispering involves generally lower lung volumes, lower tracheal pressures, higher translaryngeal flows, lower laryngeal airway resistances, and fewer syllables per breath group when compared to speaking. The use of lower lung volumes during whispering than speaking may reflect a means of achieving different tracheal pressure targets. Reductions in the number of syllables produced per breath group may be an adjustment to the high rate of air expenditure accompanying whispering compared to speaking. Performance of the normal subjects studied in this investigation does not resemble that of individuals with speech and voice disorders characterized by low resistive loads.
