Since 1982 we have been surveyed daily noise exposure and associated informations of residences in Nagoya city. Classification of measured noise patterns of residences has been made by using cluster analysis. The five typical groups of patterns are shown to exist and they are mainly related to road traffic conditions and land use nearby residence. Then in this paper noise ratings based on L_<eq> are also examined with respect to reaction of inhabitants. Scalings of reaction have been done by using Likert scale and the successive category method, on which one can quantitatively discuss the relation between L_<eq> and reaction of inhabitants to noise environment. The results show that as for L_<eq24> reactions of inhabitants are gentle below 55 dBA, moderate at 60 dBA, but severe over 65 dBA. The other noise ratings such as L_<dn>, L_<eq>M, L_<eq>D, L_<eq>E, L_<eq>N and L^^<(a)>__<eq1/6> are also considered.
