プレス工場の騒音が生体機能に及ぼす影響

Abstract

The purpose of this study was to investigate the effect of noise on human body in the press shops. The subjects were 27 healthy male students. We decided to report the significant level by examining correlations from the statistical point of view. The results obtained were as follows; 1) The results of experiment showed that blood pressure was classified, "rising" type and "falling" type. 2) Blood pressure and pluse pressure increased together. 3) Although respiration rate made no difference the respiration curve changed. 4) The amplification of EEG (electroencephalogram) amplitudes was observed under the noisy condition.
