Abstract 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).
