In a series of 68 healthy ears the muscular opening function of the Eustachian tube was assessed in two different ways. A pressure equilibration capacity of +/- 100 mm H2O was tested by a quantitative impedance technique using a pressure chamber and compared to sound transmission capacity recorded by sonotubometry at frequencies of 6, 7 and 8 kHz. In contrast to the pressure equilibration test, sonotubometry does not allow a quantitative assessment of Eustachian tube function and furthermore, sonotubometry yields false-positive as well as false-negative results due to the great variations in sound pressure generated by the deglutition maneuvers themselves.
在68只健康耳朵的系列研究中，采用两种不同方法评估了咽鼓管的肌肉开放功能。使用压力室通过定量阻抗技术测试了±100 mm H₂O的压力平衡能力，并与通过声管测量法在6、7和8 kHz频率下记录的声音传输能力进行了比较。与压力平衡测试不同，声管测量法无法对咽鼓管功能进行定量评估，此外，由于吞咽动作本身产生的声压变化很大，声管测量法会产生假阳性和假阴性结果。
