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.

受试者均为50岁至20岁的健康人，无吞咽障碍。吞咽前后的性质、长度、声压、呼吸声（呼出气或吸入气），并对受试者一次吞咽约5ml水时吞咽音的产生时间进行分析。结果，在没有吞咽障碍的健康人的吞咽中获得了简短、平淡的吞咽音，但长度和声压的个体变化都很大。吞咽前后吱吱声的性质清楚，吞咽后，根据产生的时间迅速重新开始呼吸。至于吞咽后的呼吸，有很多人呼出了空气。吞咽后呼吸时间的个体差异较大。
