摘要
目的研究阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea-hypopnea syndrome,OS-AHS)和单纯鼾症(simple snoring,SS)者鼾声的基频和共振峰特点,探讨其可能的临床应用价值。方法对50例OSAHS患者(OSAHS组,轻度16例,中度15例,重度19例)和20例SS者(单纯鼾症组)行同步多导睡眠监测和鼾声监测,截取每例患者不同睡眠时段的10次鼾声,使用Prrat语音分析软件对鼾声的基频和共振峰进行分析。结果 SS组有明显的基频,在100Hz段以下分布聚集,而OSAHS组鼾声基频无规律;SS组鼾声的第一共振峰值(F1)明显小于OSAHS组;OSAHS组中,重度组F1最高,轻度组最低,且各组间两两比较差异均有统计学意义。结论 OSAHS患者与SS者的鼾声基频和共振峰频率特别是F1有明显差别,F1值的大小与OSAHS的严重程度有一定关系,鼾声的基频及共振峰值有助于OSAHS与SS的区分以及OSAHS严重程度的大致判断;根据SS者鼾声的基频可能有助于鼾声来源的鉴别。
Objective To investigate the characteristics of formant frequency and fundamental frequency of snoring by patients with obstructive sleep apnea--hypopnea syndrome （OSAHS） and with simple snoring （SS）. Methods 50 patients with OSAHS and 20 patients with SS underwent polysomnography and simultaneously snoring recording. The patients were divided into four group： Group SS,Group mild ,Group media, and Group heavy. 10 snores were selected from each patient in different sleep stage. Fundamental frequency and formants were extracted via Praat, speech analysis software. Results Regular fundamental frequencies was found in Group SS and gathered below 100Hz, while no--regular fundamental frequencies were noted from Group OSAHS. The first formant frequency （F1） was the lowest in Group SS while the highest in Group heavy. The differences between each group were statistically significant. Conclusion Significant differences of fundamental frequency and formant frequency, especially F1, were found between snoring sounds of OSAHS and SS. F1 was relevant to the severity of OSAHS. These can differentiate SS from OSAHS, and also the severity of OSAHS.
