Few studies have ever been conducted on the influences of noise upon human creativity in spite of the emerging importance of the creativity in the learning society to come. This study aims to investigate the overall effect of it, in particular. The experiments were conducted at three elementary schools and a lower secondary school in Niigata Prefecture in the period from October, 1977 to February, 1978. Creativity tests (S-A Creativity Test, "A" or "B" type originally designed by J.P. Guilford, and "P" type originally designed by E.P. Torrance) were conducted in three groups i.e., control group under no noise exposure, and groups under 70 dBA and 80dBA noises. The noise employed in this study was 1kHz band noise generated by a noise field generator and its reproduction by a tape deck. The subjects were 527 pupils of fifth and eighth grades. The main findings are as follows: 1. The noise (band noise, central frequency 1 kHz) was uniformly obstructive on the "verbal creativity" (measured by "A" or "B" type) of school children regardless of their grade or sex. But it affected neither negatively nor positively on their "figural creativity" (measured by "P" type) as a whole. 2. 80 dBA noise was more obstructive on "verbal creativity" than 70 dBA noise, but there was no difference of effects between 80 dBA and 70 dBA noises on "figural creativity." 3. The noise was uniformly obstructive on the factors and the fields of "verbal creativity." It was accelerating on the perceptivity, the fluency and the flexibility of "figural creativity", but obstructive on the constructability of it. 4. Pupils assess 80dBA noise more obstructive to perform the creativity tests than 70 dBA noise. This difference of annoyance by noise level was clear for pupils of the eighth grade though vague for those of the fifth grade.
