The sound of an inhaling apparatus with a vibrator, introduced in both meatusses of the nose, is better heard in both ears during deglutition. This demonstrates a permeability of the Eustachian tubes. The same principle is used in the sonomanometry. We examined this phenomenon in five test persons, in whom we blocked by a pomphus the pharyngeal ostium of the tube during 90--150 min. On this occasion we found the following results: a ) The sound of the vibrator is always heard though the unblocked tube. b) There is a lateralisation in the Weber's hearing test immediately after the blockage of the tube, whereas the Rinne' test mains positive. c) The middle ear pression falls 1 mm H2O per min.
将带有振动器的吸气装置插入双侧鼻腔，在吞咽时双耳能更清楚地听到其声音。这表明咽鼓管具有通畅性。声导抗测量法也基于同样的原理。我们对五名受试者进行了此项现象的研究，在90至150分钟内用棉球堵塞其咽鼓管的咽口。在此期间我们得到了以下结果：a）振动器的声音总能通过未堵塞的咽鼓管被听到。b）在堵塞咽鼓管后立即进行的韦伯氏听力测试中出现了听觉偏侧化现象，而林纳氏测试仍为阳性。c）中耳压力每分钟下降1毫米水柱。
