Briefly, microphones were placed in the ear canals, a 45\u00b0 telescope introduced through one side of the nose to visualize and record ipsilateral ET movements, and the probe from a sound generator placed in the opposite nostril. At a generated nasopharyngeal sound level, ET movements and ipsilateral microphone signals were continuously recorded while the subject performed a series of three swallows. For each swallow, relational movements among ET structures observed on video recordings and characteristics of the sonotubometry signal envelope at the ear canal were quantified at three times: swallow onset (T1), maximum soft\u2010palate elevation (T2), and maximum ET luminal dilation (T3).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 99 swallows were analyzed. The average medial rotation of the ET cartilage and lateral wall over the T1\u2010T2 interval were \u221232.7 \u00b1 14.9\u00b0 and 7.2 \u00b1 25.1\u00b0, and over the T2\u2010T3 interval were 4.6 \u00b1 7.7\u00b0 and 6.2 \u00b1 14.6\u00b0, respectively. The transtubal sound transmission during a swallow peaked at an amplitude of 30.5 \u00b1 35.7 mV during the 572.5 \u00b1 292.6 ms of elevated sound\u2010pressure time.
