Survey of daily noise exposure of 315 residences in Nagoya City was made in the last half period of 1982. The equivalent sound levels measured nearby houses during 24 hours are analyzed by using quantification theory type I. The results are summarized as follows. 1) The prominent factors for noise exposure of residence in urban area are road and land use as easily expected. 2) The effects of factory and train for noise exposure are noise exposure are noticed in daytime and in the other time respectively. 3) The effects of season (i. e. month) and type of house evident in residual neise level, L^<90>_<eq1/6>. 4) Reduction of noise exposure by neighboring buildings as well as fence of residence is also confirmed. Based on these results we have shown that classification of urban area by land use and road is very useful for discussing environmental noise. If is interesting to know that the above classification is just corresponding to districts which has being employed to define standard values of environmental noise in our country.
