该实验通过对比受试者在背景噪声接近0 dB（A）的极静环境和普通住宅环境（背景噪声22~48 dB（A））的睡眠质量来探究噪声对睡眠的影响。35位不同性别、年龄的受试者佩戴睡眠头环监测仪，分别在极静房间和自己住宅作睡眠测试。结果发现：在极静房间与在普通住宅相比，受试者睡眠质量整体平均有所提升，睡眠总时长整体平均增加了11.4%，深度睡眠时长整体平均增加了9.3%，快速眼动睡眠（REM）时长整体平均增加了12.2%；在住宅背景噪声为30 dB（A）以上时，深度睡眠时长提升量随住宅背景噪声增大而增加。
The influence of noise on human sleep was studied by comparing people's sleeping quality in a quiet room with close to 0 dB(A) background noise to that in common bedrooms with background noise levels of 22-48 dB(A). 35 subjects of different genders and ages wore sleep evaluation head bands when sleeping in the silent room and in their bedrooms. The results show improved sleeping quality in the silent room compared with the common bedrooms with the total sleep time averagely increased by 11.4%, the deep sleep time averagely increased by 9.3%, and the rapid eye movement (REM) sleep time averagely increased by 12.2%. The improved deep sleep time positively correlates with the background noise for noise levels above 30 dB(A).
