Violent_Mind_In_Frequency

# Mind control to control people and their "illusion"
# Here we demonstrate in Hz to control, Best play low sound at 30 minutes
# always remember o be hind BT or other speakers in trial
# We have here to demonstrate people's control of vision ( can be blurred) ,Frontal Lobe, etc
# Long-term exposure to high-level noise may cause tensions and aggression in individuals; even different frequencies may # act differently and cause impairment in cognitive functions,Vision, increase human errors, may cause adverse consequences, and
#  most importantly, increase psychological reactions in social and family settings
