摘　　要：为探讨在噪声环境中的睡眠防护问题，设计了三种状态的睡眠实验：（１）安静状态，背景噪声低于４５ｄＢ（Ａ）；（２）噪声状态，环境噪声９０ｄＢ（Ａ）；（３）噪声防护状态，环境噪声９０ｄＢ（Ａ），受试者配戴耳塞。睡眠期间记录了６名受试者的脑电、眼动和肌电，分析了睡眠潜伏期，醒觉次数和时间，各期睡眠率和总睡眠率。结果表明。Sleep experiments were done in 6 subjects under 3 conditions.(1) Quiet, background noise level lower than 45dB(A); (2)Noisy with earplugs,ambient noise level 90dB(A);(3)Noisy, ambient noise level 90dB (A), and subjects wearing earplugs. EEG、REM and EMG during sleep were recorded. Sleep latency,times and duration of waking up ,sleep rate of each stage and total sleep rate were analyzed. It shows that sleep under noise condition can be improved by wearing earplugs.
