Electroencephalograms EEG and topographies of experimental subjects heard neumaticnoise have been measured. Auditory evoked potential AEP and event-related potential ERP occur one after another. Alpha waves disappear and beta waves appear as the result of analysis of frequency map. Loudness of pneumatic noise is estimated by Steavns power law used brain potential of beta wave in ERP.
In addition, physiological responses, namely, heart rate, respiration, and sweating have been measured. Influence on them through the autonomic nervous system is demonstrated. Explanation based on function of the brain is given. Subjects fall into two categories, using a personality test. Even subjects who are hard to feel the stress are influenced by the pneumatic noise. These results indicate that the pneumatic noiseis stressor.
