✦ Synopsis

Many laboratory and "eld studies of the e!ect of noise on sleep have been performed where subjects sleep whole nights. It was suggested from our former studies that the most serious e!ect of noise on sleep is disturbance in falling asleep and that people have to make e!orts to try to sleep in noisy situations. In this study, the e!ort to fall asleep was used as an index of sleep and the e!ect of various physical properties of sounds was examined. Subjects were asked to try to sleep listening to sounds presented with a mini-disk and they were allowed to switch o! the sound after 1 h if they could not sleep. The results suggest that (1) whether subjects can sleep within 1 h after they start to try to sleep is a good index of the e!ect of noise on sleep and that ΒΈCO is a good index of the e!ect of noise on sleep except for the sounds which have meanings such as songs and people's talk.

Twelve subjects were each exposed to the noise of passing trucks at peak levels of 45, 50, 55 and 60 dB(A) for 15 min intervals throughout the night each for seven to 12 nights. Effects of the noise were observed by sleep electroencephalograpy (EEG). Three EEG parameters were affected by the noise e
