Recently, various kinds of sounds are flooding over in our living environment. For the relation between sound environment and people, we have been obtained a lot of information from researches of noise evaluation. On the other hand, in the familiar environment, we research a significant attribute of each sound. It is important to consider the relationship between receivers of sounds and sounds or sound makers, and those circumstances as the whole issue of sounds. In this research, we concentrate a significant attribute that sounds have, and investigate the system that acknowledges living environmental sound by examining how people feel the environmental sounds in their life. As a result, we could obtain following information. (1) For the reason people are conscious of living environmental sounds and feel comfort/discomfort for sounds, the environmental factor whether sounds fit to the environment or not would exist. (2) The relationship between a living environment and each sound is suggested to be classified into following four categories. i) An impression of the scene and the living environmental sound are agreed. ii) Particular sound has strong effect. iii) A comprehensive of comfort/discomfort for all subconscious living environmental sound decides the degree of comfort/discomfort of the whole scene. iv) The scene and living environmental sounds are separated.
