摘要： 目的利用颈部听诊法分析健康青年人在自主控制吞咽时吞咽音的参数变化。方法37 名健康青年志愿者分别进行3ml 和10 ml 水的吞咽，吞咽方式设定为用力吞咽、正常吞咽以及轻吞咽，利用颈部听诊技术采取志愿者的吞咽声，并将采取的声音进行电脑声学参数分析，主要选择吞咽音间期(SSD)、平均吞咽音振幅(ASA)和平均声谱频率(MSF)3 个参数数据，对不同吞咽方式下以及不同水容量下的吞咽音进行比较。结果用力吞咽时MSF 高于其他两种吞咽方式(P<0.05)；10 ml 水吞咽时SSD、ASA和MSF 均明显高于3 ml 水吞咽(P<0.01)。结论健康人对吞咽动作进行主动控制时，吞咽声音的频率体现健康青年人对吞咽方式主动控制的变化，下咽液体容量变化时吞咽声音的声音间期、平均频率以及平均振幅均发生变化。

Abstract: Objective To analyze the change of swallowing sounds in healthy youth by cervical auscultation (CA). Methods 37 young volunteers swallowed 3 ml and 10 ml water respectively by forced swallowing (FS), normal swallowing (NS) and soft swallowing (SS), the swallowing sounds were collected by CA, and the swallowing sound duration (SSD), average swallowing sound amplitude (ASA) and mean swallowing sound spectral frequency (MSF) were compared among different swallowing ways and water volumes. Results MSF was higher in FS than in NS and SS (P<0.05). All the indexes were significantly higher in 10 ml water than in 3 ml water (P<0.01). Conclusion Healthy swallowing sound recorded by CA can be volitionally controlled by the healthy individual consciousness in swallowing ways and the liquid volumes. SSD, ASA and MSF of the swallowing sound increase with water volume.
