中国大学生主要居住在四人间甚至六人间卧室，室友的声音可能会影响他们的睡眠。因此，本研究的目的是调查不同声源和声级对中国大学生睡眠的影响。基于睡眠质量测量、声环境测量以及对中国哈尔滨市典型宿舍90名参与者的问卷调查，结果如下：首先，68.89%的大学生存在睡眠不足的情况，其中室内噪声是15种干扰因素中影响最大的环境因素，干扰了50%的大学生。其次，每个房间的居住人数是影响睡眠背景声音水平的重要因素。当乘员人数为两人时最高，当乘员人数为五人时最低。第三，深度睡眠时间和快速眼动 (REM) 睡眠时间每 1 dBA（A 权重分贝）分别减少 1.7 分钟和 1.4 分钟，R-2 = 0.352 和 0.332 (p < .001)。从声源对睡眠的影响来看，睡眠主要受到室友谈话的干扰（77.42%），室友睡眠相关活动引起的噪音是最常见的活动源（67.74%）。本研究可为通过改善声音环境帮助提高中国大学生的睡眠质量提供指导 (C) 2018 Elsevier B.V. 版权所有。
Chinese college students reside primarily in four-person bedrooms and even six-person bedrooms, where the sound from roommates may affect their sleep. Therefore, the purpose of the present study is to investigate the effects of different sound sources and sound levels on sleep for college students in China. Based on sleep quality measurements, acoustic environment measurements, and a questionnaire survey with 90 participants in a typical residence hall in Harbin city, China, the results are as following: First, 68.89% of college students experienced sleep deprivation, and indoor noise was the most influential environmental factor among 15 disruptors that disturbed 50% of college students. Second, the number of occupants per room was a significant factor affecting the background sound level of sleep. which was highest when the number of occupants was two, and lowest when the number was five. Third, deep sleep time and rapid eye movements (REM) sleep time decreased 1.7 min and 1.4 min per 1 dBA (decibel with A-weight), with R-2 = 0.352 and 0.332, respectively (p < .001). In terms of the effect of sound sources on sleep, sleep was mostly disturbed by roommate conversation (77.42%), and noise caused by roommate sleep-related activities was the most common source of activities (67.74%). The present study can provide guidelines to help enhance the sleep quality of Chinese college students through improvements in the sound environment (C) 2018 Elsevier B.V. All rights reserved.
