Question About Low Frequency Sounds


I came across the following info on the internet and I can't figure out whether it makes any sense or not.

Sound frequencies below 20Hz (even up to 30Hz) can directly affect states of consciousness. For those of you who don't know, our brains vibrate at different frequencies depending on the level of awareness (consciousness) we are in. Consciousness lies on a continuum. The scale is as follows:

.5-3Hz - Delta. This is the sleep state.
4-7Hz - Theta. The meditative/hypnotic state.
8-12Hz - Alpha. The "relaxed alert" state.
13-20Hz - Beta. Normal wakeful consciousness.
20-32Hz - High beta. Manic states.

Does anybody know anything about this? If true, it's implications on music reproduction could be profound.

Perhaps that would explain why getto thugs are so prone to violence. Too much deep base (20-30 herts, Maniacal state). All along I thought it was that they were simply animals that have broken the fabric of soceity.
