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.
