Measurements of eivironmental noise all day long nearby residence are made by using L_&lteq&gt meter which stores L_&lteq1/6&gt for every ten minutes. 315 samples (i. e. one sample/km^2) are collected uniformly in Nagoya City during later half of '82. Associated informations around residence and reactions of inhabitants to noise environment are also obtained in this survey. The results are summarized as follows. 1. Average value of L_&lteq24&gt was 60 dBA. Refering to average L_&lteq&gt in daytime, those values in the morning(also in the evening) and in the night were lower by 4dBA and 9dBA respectively. 2. Residence in commercial area was exposed to higher level of noise by 5dBA comparing with residence in other area. 3. Influence of trunk roads on environmental noise was strong enough that the area nearby them exceeded the other area in noise exposure by 10dBA. 4. Reactions of inhabitants to environmental noise were found to become severe when L_&lteq24&gt around residence exceeds 60dBA. Below 50dBA there seem little problems about noise.
