| Research Abstract |
The subjects were healthy persons who did not have 50-year-old from 20 swallowing impaired. The properties, length, acoustic pressure, breath sound of before and behind the deglutition (expired air or inspired air), and the generated timing of the swallowing sound at one time swallowing of water about 5ml were analyzed with subjects.
As a result, a short, plain swallowing sound was obtained in the deglutition of the healthy person who did not have the swallowing impaired, but both length and acoustic pressure individual variations were large. Properties of the creaking sound before and behind the deglutition were clear, and after the deglutition, breath was promptly restarted as for the generated timing. As for breath after the deglutition, there were a lot of people of the expired air. The individual variation of timing that breath after the deglutition restarts was large.
