Acoustic characteristics of snoring sound, such as pitch and formant, differed according to the site of upper airway obstruction determined by sleep videofluoroscopy (SVF). Snoring sound analysis can complement determination of the site of obstruction in snoring and sleep apnea patients.
The aim of this study was to evaluate the acoustic characteristics of snoring according to obstruction site determined by SVF.
Ninety patients who underwent simultaneous snoring sound recording during SVF were included in this study. Acoustic parameters of snoring such as pitch (min, mean, max) and formant (1,2) were analyzed. Site of obstruction was determined by SVF and classified according to anatomic structure and level of obstruction.
Mean value of peak frequency showed significant difference between soft palate and isolated tongue base or epiglottis obstruction and combined obstruction involving soft palate and tongue base or epiglottis. Peak frequency of velopharyngeal obstruction showed difference only with hypopharyngeal obstruction. First formant showed similar results in the structure classification whereas velopharyngeal obstruction showed significant difference compared with other levels of obstruction. Other parameters (intensity, jitter, shimmer) did not show significance according to site of obstruction.
根据睡眠荧光透视检查（SVF）确定的上气道阻塞部位，鼾声的声学特征（如音高和共振峰）存在差异。鼾声分析可辅助确定打鼾和睡眠呼吸暂停患者的阻塞部位。
本研究旨在根据SVF确定的阻塞部位评估鼾声的声学特征。
本研究纳入了90例在SVF过程中同时记录鼾声的患者。分析了鼾声的声学参数，如音高（最小值、平均值、最大值）和共振峰（第一共振峰、第二共振峰）。通过SVF确定阻塞部位，并根据解剖结构和阻塞程度进行分类。
软腭与孤立的舌根或会厌阻塞以及涉及软腭和舌根或会厌的联合阻塞之间，峰值频率的平均值存在显著差异。腭咽阻塞峰频率仅与下咽阻塞存在差异。在结构分类中，第一共振峰显示出类似结果，而腭咽阻塞与其他阻塞程度相比存在显著差异。其他参数（强度、基频微扰、振幅微扰）根据阻塞部位未显示出显著性差异。
