To quantify the snoring sound intensity levels generated by individuals during polysomnographic testing and to examine the relationships between acoustic, polysomnographic, and clinical variables.
The prospective acquisition of acoustic and polysomnographic data with a retrospective medical chart review.
A sleep laboratory at a primary care hospital.
All 1,139 of the patients referred to the sleep laboratory for polysomnographic testing from 1980 to 1994.
The acoustic measurement of snoring sound intensity during sleep concurrent with polysomnographic testing.
Four decibel levels were derived from snoring sound intensity recordings. L1, L5, and L10 are measures of the sound pressure measurement in decibels employing the A-weighting network that yields the response of the human ear exceeded, respectively, for 1, 5, and 10% of the test period. The Leq is a measure of the A-weighted average intensity of a fluctuating acoustic signal over the total test period. L10 levels above 55 dBA were exceeded by 12.3% of the patients. The average levels of snoring sound intensity were significantly higher for men than for women. The levels of snoring sound intensity were associated significantly with the following: polysomnographic testing results, including the respiratory disturbance index (RDI), sleep latency, and the percentage of slow-wave sleep; demographic factors, including gender and body mass; and clinical factors, including snoring history, hypersomnolence, and breathing stoppage. Men with a body mass index of > 30 and an average snoring sound intensity of > 38 dBA were 4.1 times more likely to have an RDI of > 10.
Snoring sound intensity levels are related to a number of demographic, clinical, and polysomnographic test results. Snoring sound intensity is closely related to apnea/hypopnea during sleep. The noise generated by snoring can disturb or disrupt a snorer's sleep, as well as the sleep of a bed partner.
量化个体在多导睡眠图测试期间产生的打鼾声强度水平，并研究声学、多导睡眠图和临床变量之间的关系。
前瞻性采集声学和多导睡眠图数据，并回顾性查阅病历。
一家初级保健医院的睡眠实验室。
1980年至1994年间转诊至睡眠实验室进行多导睡眠图测试的所有1139名患者。
在进行多导睡眠图测试的同时，对睡眠期间的打鼾声强度进行声学测量。
从打鼾声强度记录中得出四个分贝水平。L1、L5和L10是采用A加权网络以分贝为单位的声压测量值，分别表示在测试期间1%、5%和10%的时间内超过人耳响应的值。Leq是波动声学信号在整个测试期间的A加权平均强度的度量。12.3%的患者L10水平超过55 dBA。男性的打鼾声平均强度水平显著高于女性。打鼾声强度水平与以下因素显著相关：多导睡眠图测试结果，包括呼吸紊乱指数（RDI）、睡眠潜伏期和慢波睡眠百分比；人口统计学因素，包括性别和体重；以及临床因素，包括打鼾史、嗜睡和呼吸暂停。体重指数>30且平均打鼾声强度>38 dBA的男性患RDI>10的可能性高4.1倍。
打鼾声强度水平与许多人口统计学、临床和多导睡眠图测试结果相关。打鼾声强度与睡眠期间的呼吸暂停/低通气密切相关。打鼾产生的噪音会干扰或扰乱打鼾者本人及其同床伴侣的睡眠。
