Using , you can coax your brainwaves to a certain frequency, and in doing so, achieve the mental state associated with that frequency. The medium used to do this varies - some of these parties used devices that generated EM fields which were applied to a precise part of the body, while others used vibration and sound. I don't have any experience with using EM fields - most of my personal toying about with this stuff uses a sound medium. The sources of these frequencies claimed that they could affect humans in a variety of ways. The information I've added is in violet. My personal comments are in light blue. Hyperlinked words have glossary definitions that you can access by clicking on them. This is also where I'll give any indications about what medium the source for the information used sound, light, EM fields, or vibrations. By default, assume it to be sound. If you want to redistribute this, please include the Bibliography page as well -- the original sources deserve their reference. Also, please leave my introduction at the top as it is, along with my name, email, and URL. Disclaimer : I wouldn't take everything you read on this list for granted. Some of it is verifiable by science -- and, there's probably a lot of new-agey crap as well. Although the mere fact some of it sounds new-agey in itself doesn't mean there isn't some truth to it. The powers that be might have just been too imaginative naming it. Disclaimer 2 : Anything you do with the frequencies below is your personal risk - if you manage to burn out a couple of brain cells or harm yourself in some other way, I do not take any responsibility nor will I be held liable. Just protecting my butt here. The two- or three-character source codes after each frequency are defined in the. Access to unconscious information. Dominant brainwave in infants under one year old. This range normally decreases when we focus, but this doesn't happen when a person with ADD - delta waves actually increase when they try and focus. They all play simultaneously. May benefit dyslexics + people with Alzheimer's. Can lead to trance-like states. Theta strong during internal focus, meditation, prayer + spiritual awareness. Reflects state between wakefulness+ sleep. Observed in anxiety, behavioral activation+behavioral inhibition. Promotes learning+memory when functioning normally. I think they mean it helps you process what you've learned - if you tried to actively learn while in the theta state, I doubt you'd have success - but sometimes the theta state can give your subconscious a chance to chew the proverbial fat that you've learned during the day, and digest it. Abnormal in awake adults, but seen in children up to 13 years old. When moved to 4HZ these individuals showed marked improvement in the length of time between the occurrence of exhaustion after certain exercises were completed. C onsists of trains long runs of rhythmic frontal activity centering at 6. It probably ties into what the 5. I think this is slightly off - most sources consider the lowest frequency of the Schumann Resonance to be 7. One needs to be careful to distinguish between octaves of the 7. Some paint Alpha as a range of relaxed attentiveness, ideal for learning. I see the Alpha range as the fine line between daydreaming and alertness. It's like a baseball player on a base - he'll move away from the base, so that he can steal if the opportunity presents itself. But he always stays close enough to the base so he can get back in case the pitcher throws the ball to the baseman. But we can also quickly retreat into the realm of sleep if need be. Here's the thread from the Brainwave Generator message board : 9. They're also often detected during dream sleep. It was their conclusion. A more desirable frequency band than 12 to 15-Hz is 11. For the former, he suggests 36 to 44 HZ. This effect seems the strongest around 20 HZ. While other sources equate this frequency range with stress, I'm thinking it might be like the roar of a car engine - in small doses, it can be quite a rush, but too much of it can lead to a headache. The system is funny like that. Causes distress during labor. Some effects have been observed, but currently not enough research has been done in this area, to prove, or disprove, anything. It then considers 60 to 120 to be the Lambda range. I had originally thought it was related somehow to the Schumann Resonance at 33 HZ, and I was wrong. I've had some interesting results with this one -- particularly when I overlap waves at 9. The mind tends to wander in funny ways. Helps To Maintain Alertness. Associated with high-level information processing. Rodolfo Llinas a professor of neuroscience at New York University. The average frequency is in the ~39. A 40-Hz rhythm occurred just prior to the subject's answering the question. Forty--Hz pulses are thought to lead to synchronization + coordination of neurons assigned to the processing of incoming sensory stimulation. Their guessing was about as accurate as random chance, BUT when they had their eyes on the correct card that would inevitably turn up, the amount of 40HZ activity registering in their brain was higher. Go here for more information: 45. Although, I'm including it since it's a very specific frequency. I'll research it further and try to dig up some additional information. Also, most ELF research is now Govt classified, particularly since the mid-1960's when Hamer discovered behavioral effects as the result of applied sinusoidal field gradients as low as 4 volts. Appears to be involved in stimulating 5-hydroxytryptamine production, with 160Hz. An additional undertone in the alpha range of frequencies sometimes helps too. My money is on the second, since there is another frequency that is given for the Earth year. It leads to a state where being has no name, to a state where the all-one and the all encompassing are no longer separate entities but are reunited at their one common origin, the origin that is also you. I suppose you could associate the earth year with the sun, since it's the time it takes the earth to go around the sun, but 126. See the comments with that frequency for more. I'll have to research that further. He had said he'd go into more detail when Awakening Mind II is released. I'm just a little, little bit skeptical of this one, but if anybody has any luck with it, let me know. The associations might tie in with something astrological instead. One source might have done a typo, and then other sources based their information from that. A quarter note, perhaps. Sixth harmonic of six, center of the brainwave spectrum. One could justifiably call it Ab. It's probably closer to Ab than it is to A. Proponents of this change indicate music played with a 432 tuning is more pleasant, brighter, and easier on the ears. They also indicate it promotes meditation and relaxed states, and the tuning as a whole resonates with the heart chakra. The tuning has been presumably used by ancient Egyptians, ancient Greeks, and in some classical music example - Giuseppe Verdi. They're indicating that a diatonic scale with this as the center does. It may seem nitpicky, but it's worth mentioning. I'm not sure if they're perhaps basing this on some older scale. The frequencies that notes exist at have changed over the years. Go see a doctor. However, if you do want to tinker around, this frequency was used as an EM field, not a sound. I'm not sure if it would work as a sound. Use at your own risk. See disclaimer for 500 HZ. See disclaimer for 500 HZ. See disclaimer for 500 HZ before even playing with this. See disclaimer for 500 HZ. A subharmonic of the frequency of quartz crystal. Some claim it energize crystals in the brain. Others say that it activates aspects of the auric field. See disclaimer for 500 HZ. Fastest recharge at 8000 HZ.
