Effectiveness of sound...It is common knowledge these days that music affects plants. Research also show that music and all frequencies affect humans as well. In the book "Dynamic DNA" Dr. Hari Sharma describes the effects of sound on the human physiology (on the level of the brain/limbic system, on the level of the body chemistry, and on the level of cellular function), and lists proposed mechanisms through which sound has these measured effects. He says we cannot escape the very real influence of the environment on us which happens "at the epigenetic level, and hence on the DNA."
Computing power of the human brain is great. We need to learn to use it more.
