Abstract: The effects of noise [95dB (A)] on human body were studied in the press shops noise. The subjects were 15 healthy male students. The results of preliminary experiment showed that changes in subject's blood pressure due to the noise exposure were classified into two types; "rising" type (80% of the subjects) and "falling" type (20%). Only the subjects of the "rising" type were participated in main experiments. The results obtained were as follows; 1) Blood pressure and pulse pressure were increased to a great extent under the noisy condition. 2) Heart rate and brinking rate were decreased during the period of noise exposure. 3) Respiration rate was found to be unchanged between the periods of noise exposure and non-exposure; however, respiratory magnitude showed the difference between the two periods. The respiratory magnitude found in the period of noise exposure was shallower than that in the non-exposure period. 4) The θ waves of EEG amplitude which was not found in the condition without noise were observed in the noisy condition.
