By Using the data obtained from the recent survey of personal noise exposure in daily life, we examined the equivalent sound level Leq during sleep of each subject. Among 210 subjects in and near Nagoya city about 60% of them were in rather good acoustical environments less than 40 dBA during hours of sleep except each transient one hour after going to bed and before getting up. The average Leq of each transient one hour mentioned above was higher by 4 dBA than that of the hours of sleep between them. Although short in duration, 10 minutes or so, about 25% of the subjects were exposed to noise higher than 60 dBA which might disturb their sleep. It was also found that the acoustical environments during sleep are considerably affected by the road traffic and the commercial activities near residence.
