本研究的目的是描述吞咽声音的特征，并确定在吞咽过程中的声音产生的过程中，在年轻的健康成年人。33名健康志愿者被招募并被分配到三个实验组。在实验1中，将麦克风连接到20名受试者的8个宫颈部位之一，参与者吞咽5 ml水，并记录声音波形。在实验2中，10名受试者在录音期间吞下0、5、10或15毫升水。此外，参与者以两种不同的颈部姿势消耗5 ml推注。在实验3中，当三名参与者消耗5 ml碘帕醇溶液时，同时记录声音波形和视频透视。分析所有实验组中波形的持续时间和峰强度比。波形的声学分析和视频透视显示，吞咽音可分为三个阶段，每个阶段与吞咽运动的一个阶段相关联：口腔阶段包括舌后和舌骨运动，咽阶段包括喉运动、舌骨抬高、会厌闭合和食团通过食管口;复位阶段包括舌骨和喉返回到它们的静止位置，以及会厌的重新打开。通过对吞咽音的声学分析和X线透视，我们发现吞咽音可分为三个阶段：口腔期，包括舌和舌骨的后移;咽期，包括喉运动、舌骨抬高、会厌闭合和食团进入食管口;复位阶段包括舌骨和喉的复位以及会厌的重新打开。
The purpose of this study was to characterize the swallowing sound and identify the process of sound generation during swallowing in young healthy adults. Thirty-three healthy volunteers were enrolled and allocated into three experimental groups. In experiment 1, a microphone was attached to one of eight cervical sites in 20 subjects, participants swallowed 5 ml water, and the sound waveform was recorded. In experiment 2, 10 subjects swallowed either 0, 5, 10, or 15 ml water during audio recording. In addition, participants consumed the 5 ml bolus in two different cervical postures. In experiment 3, the sound waveform and videofluoroscopy were simultaneously recorded while the three participants consumed 5 ml iopamidol solution. The duration and peak intensity ratio of the waveform were analyzed in all experimental groups. The acoustic analysis of the waveforms and videofluoroscopy suggested that the swallowing sound could be divided into three periods, each associated with a stage of the swallowing movement: the oral phase comprising posterior tongue and hyoid bone movement; the pharyngeal phase comprising larynx movement, hyoid bone elevation, epiglottis closure, and passage of the bolus through the esophagus orifice; and the repositioning phase comprising the return of the hyoid bone and larynx to their resting positions, and reopening of the epiglottis.
