摘要通过自测睡眠分数、多导睡眠参数和次日早晨的性能测试，研究了噪声环境下的睡眠习惯。睡眠质量自评问卷（OSA）包括困倦、睡眠维持、忧虑、综合睡眠感觉和睡眠启动5个主观睡眠质量因子。多导睡眠参数包括6个睡眠阶段（以分钟计）、睡眠潜伏期、REM潜伏期、REM周期、REM持续时间、睡眠期间觉醒的频率和持续时间（以分钟计）、总睡眠时间、睡眠阶段转换数、睡眠效率、睡眠纺锤波数和密度。还检查了当晚和第二天早上睡觉前的反应时间之间的差异。受试者是12名年龄在19至21岁之间的学生，他们总共接受了96个晚上的测试。每个主题睡在一个实验室，并暴露于记录通过卡车噪音与峰值水平为45，50，55和60分贝（A）的时间间隔为15分钟。显着的变化被认为是在第1阶段，MT，觉醒的频率和睡眠阶段转移的数量。作者推测，随着嘈杂的夜晚不断重复，浅层睡眠的减少反映了夜间睡眠对重复通过的卡车噪音的习惯，其间隔，持续时间和性质是恒定的。
Abstract Habituation of sleep to a noisy environment was investigated by self-rated sleep scores, polygraphic sleep parameters, and a performance test on the following morning. The self-rated sleep questionaire, OSA, includes five factors of subjective sleep quality: sleepiness, sleep maintenance, worry, integrated sleep feeling and sleep initiation. The polygraphic sleep parameters were six sleep stages in minutes, sleep latency, REM latency, REM cycle, REM duration, frequency and duration in minutes of awakening during sleep, total sleep time, number of sleep stage shifts, sleep efficiency, number of sleep spindles and density. The differences between reaction times before sleep that night and the following morning were also examined. The subjects were twelve students aged 19 to 21 who were tested a total of 96 nights. Each subject slept in an experimental room and was exposed to recorded passing truck noise with peak levels of 45, 50, 55 and 60 dB(A) at intervals of 15 min. Significant changes were recognized in Stage 1, MT, frequency of awakening and number of sleep stage shifts. The authors speculate that the decrease in the shallow stage as noisy nights were repeated reflects habituation of night sleep to repeated passing truck noise, whose interval, duration and nature was constant.
