抄録: Noise has become one of the serious social problems as human civilisation develops. This study aims at pointing out some aspects of the influence of noise upon human intelligence in the case of school children. The specific purpose of this study is to examine the following points : 1. Influence of noise upon the "intelligence" of school children as a whole. 2. Influence of noise upon each factor of "intelligence". 3. Its variation by the difference of noise level. 4. Its variation by the difference of personality. 5. Its variation by the difference of levels of intelligence development. 6. The difference of influence of continuous and intermittent noise. 7. Its variation by the difference of age. The experiments were conducted at two elementary schools and a lower secondary school in Niigata and Miyazaki Prefectures in the period from February, 1972 to July, 1973. Intelligence test (Todai A-S Intelligence Test, H Version) was administered in 3 groups, i.e., control group under no noise exposure, and groups under continuous 2 KHz noises of 70 dBA and 80 dBA at an elementary school. It was conducted in 3 groups, i.e., control group under no noise exposure, and groups under 1 KHz continuous and intermittent noises of 80 dBA at an elementary school and a lower secondary one. The noises employed as stimuli in the experiments were 1 KHz and 2 KHz band noise generated by a noise field generator and its reproduction. The subjects were 261 male and 212 female pupils ranging from 9 to 15years old. The findings are as follows : 1. The noise employed had obstructive effects upon "intelligence" as a whole. 2. The effect was more obstructive upon logical thinking than upon intuitive one. It was more obstructive upon figural thinking than upon verbal one. 3. The effect varied according to the personality of pupils. 4. It was more obstructive upon highly intelligent group. 5. Continuous noise had a more obstructive effect upon "intelligence" than intermittent one as a whole. 6. The effect was uniformly obstructive regardless of age.
