This paper describes some results of questionnaire in residential areas and nonresidential areas in Nagoya City. Responses of inhabitants for questionnaire and noise sources around residence are analyzed using AIC and quantification theory, which explains all contributions of noise lebel and other factors for inhabitants' responce. The results are summarized as follows. (1) Main factor is road traffic in the responses of noisiness around residence. In Honami, well correlative factors are land use, distance from factory and noise ratings. In Jiyugaoka, contributions of traffic noise in the night is particularly detected in the responses. (2) Distance from noise sources is the most highly correlated factor in the responses of noise sources around residence. The rate of contributions of noise sources and noise lebel are relate to the responses of industrial noise and railway noise. (3) The factors, such as noise sources and land use show good correspondence to Leq24 in Honami, and traffic noise has some influences to Leq24 in Jiyugaoka
