A computerized airflow/air pressure analysis system, the Aerophone II Model 6800 (Kay Elemetrics Corp.), was used to assess the effects of age and gender on laryngeal aerodynamics. A sample of 56 male and 53 female normal speaking subjects was divided into six age groups (20-30; 31-40; 41-50; 51-60; 61-70 and 71-80 years). The laryngeal aerodynamic parameters measured included phonatory (mean) flow rate, estimated subglottal pressure, laryngeal airway resistance, phonatory sound pressure level, phonatory power, and phonatory efficiency. Most comfortable phonation, vocal efficiency, and running speech tasks were used to collect the aerodynamic data. Comfortable pitch and loudness levels were used for each of these tasks. Age and gender effects were found for a number of the phonatory (mean) flow rate and phonatory sound pressure level values. Results failed, however, to indicate age or gender effects for the estimated subglottal pressure, laryngeal airway resistance, phonatory power and phonatory efficiency parameters. High intersubject variability was found for the phonatory flow rate, laryngeal airway resistance, phonatory power and phonatory efficiency values. Estimated subglottal pressure values, however, appeared to vary the least among subjects. The results are discussed with respect to factors that might influence laryngeal aerodynamics, such as underlying laryngeal anatomical and physiological age-related changes and gender-related differences. The clinical implications of the findings for the assessment and treatment of individuals with voice disorders using the Aerophone II are also discussed.
使用一种计算机气流/气压分析系统——Aerophone II 6800型（Kay Elemetrics公司）来评估年龄和性别对喉部空气动力学的影响。选取了56名男性和53名女性正常发声受试者作为样本，将其分为六个年龄组（20 - 30岁；31 - 40岁；41 - 50岁；51 - 60岁；61 - 70岁和71 - 80岁）。所测量的喉部空气动力学参数包括发声（平均）流速、估计的声门下压力、喉部气道阻力、发声声压级、发声功率和发声效率。通过最舒适发声、发声效率和连续言语任务来收集空气动力学数据。这些任务中的每一项都采用了舒适的音高和响度水平。在一些发声（平均）流速和声压级值方面发现了年龄和性别的影响。然而，结果并未表明估计的声门下压力、喉部气道阻力、发声功率和发声效率参数存在年龄或性别影响。在发声流速、喉部气道阻力、发声功率和发声效率值方面发现受试者之间存在很大差异。然而，估计的声门下压力值在受试者之间的变化似乎最小。针对可能影响喉部空气动力学的因素，如潜在的喉部解剖学和生理学上与年龄相关的变化以及与性别相关的差异，对结果进行了讨论。还讨论了使用Aerophone II对嗓音障碍患者进行评估和治疗时这些发现的临床意义。
