In this paper, the relationship between sound pressure and distance is described. We carried out an experiment, as a fundamental study to develop a machine with hearing characteristics of humans, on how accurately the intensity of a sound that is audible to humans and the distance from the sound source there of can be presumed. The method employed was AHP analysis. As a result of the experiment, the relationship between the intensity of the sound which a subject heard and the distance from the sound source was found to be consistent. The sound intensity value obtained experimentally was similar to the theoretical value for the distances from the sound source of up to 1 m. We utilized a white noise and a pink noise. We compared the a characteristics of noise and pure sound. The characteristics of the that two kinds of noise were found to be similor. The experiment clarified the differences between the characteristics of noise and those of pure sound.
