The purpose of this study is to analyze the effects of the auditory stimulation using pop music on EEG. The subjects in the study were eight healthy university students; five men and three women, age group of 22-28 years old. EEGs were measured for one minute at 19 channels, according to the international 10-20 system method, after both pop musics which the subject likes and not were provided with 100% and 50% volume of standard value, respectively, and the ratio of β/σ was obtained. As a result, when the subjects heard their favorite music, the values of β/σ ratio at the Right-Parietal.Temporal.Occipital lob(T6, O2) showed to be lower than stable state in the situation with 50% volume of standard value.
