This study assessed a sample of normal-speaking individuals' ability to discriminate differences in their self-generated intraoral air pressures. Two conditions were employed: (1) open tube in which subjects had to sustain an expiratory breath stream to maintain the target pressure, and (2) closed tube in which there was complete resistance to the subjects' breath stream. Analysis of variance revealed no significant difference (p > 0.05) in subjects' ability to discriminate differences in their self-generated intraoral air pressure as a function of open or closed tube conditions. However, subjects' discrimination scores significantly increased (p < 0.05) as the standard pressure was increased.
本研究评估了正常说话个体辨别自身产生的口腔内气压差异的能力。采用了两种条件：（1）开放管，受试者必须维持呼气气流以保持目标压力；（2）封闭管，对受试者的气流有完全阻力。方差分析显示，受试者辨别自身产生的口腔内气压差异的能力，在开放管或封闭管条件下没有显著差异（p>0.05）。然而，随着标准压力的增加，受试者的辨别分数显著提高（p<0.05）。
