The experiment was conducted using a full range pass sound, and low range pass sound which is not including high frequency band width to 26 subjects and was measured amounts of brain wave activity in 4 different type of brain wave frequency, delta, theta, alpha and beta waves respectively. State of activity of brain wave was also expressed on brain wave map. At the same time, Profile of Mood States (POMS), brain reaction by personality and psychological evaluation were also examined. As the result, we obtained that ultra sound wave affects to human brain with statistically significant.
