뇌파를 이용한 KTX 실내소음에 따른 스트레스 분석

Abstract

The aim of this study is to observe and detect a change of human's brain wave due to stress caused by train interior noise. Train's interior noise has changed by trains situation, for example, trains speed, type of trains and environments, particularly interior noise change rapidly, when traines pass through the tunnel. EEG(electroencephalogram) is records of the electrical activity of human brain, and it is changeable according to external stimulus. The wave, wave, wave, wave and wave, which are divided by frequency band width, were analyzed especially to research a brain's condition, such as stress, concentration, drowsiness. Particularly wave and wave, which are deeply involved in relax and stress. Using these properties, we could compare stress level depending on the type of trains and environments
