The Effect of Noise on Average Beta EEG Signal

Abstract

Someone who works indoors will always be exposed to noise. In this study, the influence of noise factors on cognitive performance, especially in decision making using beta signal of Electroencephalography (EEG) was investigated. The parameter used to measure cognitive performance is the average beta signal. An increase in the average beta signal indicates an increase in the function of attention. The type of research used is an experimental design. The variables involved in the study were sound intensity of 45 and 85 dB. The instrument used to measure beta signal was Muse Headband and cofnitif performance was Stroop Test. The subjects involved in this study were ten students with balanced proportions of 5-males and 5-females. The research was conducted at the Ergonomics Laboratory and Work System Design (EPSK), Department of Industrial Engineering, University of North Sumatra. The results showed a significant effect between the sound intensity factor on the average beta signal. The gender factor has no significant effect on the average beta signal. However, on average, female subjects had a higher level of attention than male subjects. So this indicated that can be used as a basis for considering the noise factor on Student Cognitive Performance.
