But again, when it comes to subjective experience, and mental evolution, I would have to caution you to take what anyone says with a grain of salt.  Obviously people want to sell these products.  There are some good ones out there and there are some bad ones out there.  There are differences in quality, as well as differences in intent with how the audios are to be used.
By the end of just a few short days (3 or 4 of use), my constant “on edge” feeling completely dissipated. I had changed my lifestyle drastically to a very low-stress environment. All feelings of anxiety disappeared rapidly, but I was still experiencing something “physical.” I had trouble explaining it to anyone. I lashed out immediately at the slightest frustration. I tried to explain to those around me that it was something physically happening in my brain, but they were skeptical. Within less than a week of using the EOC cd’s, I noticed my tolerance level for dealing with people and situations had increased tremendously.

There isn’t really a one-size-fits-all track or frequency range which is right for all kids while doing homework. So that does make it difficult to recommend one thing in particular, and why I have a number of tracks for studying and focus. If they have already learnt and understood the information, but are just trying to commit it to memory for a test, then I would recommend an alpha track, like the Memorization Study Aid product I have with the 10.4Hz frequency you referred to. If they are still trying to fully understand what is being taught in a workbook, then I would recommend a track that is mainly beta frequencies, like my Study Focus tracks. In the middle, I have a number of tracks which use a combination of beta and alpha wave frequencies, like Study Booster, Study Enhancer and Cognition Enhancer. The last 3 use similar frequencies but deliver the tones and brainwave entrainment effects in different ways. As we are all wired a little differently it does sometimes take a bit of trial and error, to see what method or frequency range works best for the individual. These types of tracks are made for a general audience. In an ideal world, you would hook up to an EEG and see in real time exactly what a person responds to best, depending on the goal and current state of mind.

Research: the authors stated that qualitative electroencephalogram signatures needed to be developed for different disorders and tested using standard validated methods of psychological assessment. Larger RCTs were needed with clear inclusion criteria for participants. The RCTs should measure qualitative EEG, hormone levels and the time of day of the intervention. Interventions protocols should be clearly defined and the relationship between session frequency/ duration and outcomes should be explored. More studies of auditory stimulation were needed, as well as studies comparing different types of stimulation, monaural, binaural and isochronic beats and use of white noise versus music.

Hi Pajaro. It is difficult to pinpoint exactly why and they probably didn’t want to make assumptions without conclusive evidence. Do you suffer from ADD? Or do you struggle to focus? The reason I ask is because of this: “Peak performers’ decrease Delta waves when high focus and peak performance is required. However, most individuals diagnosed with Attention Deficit Disorder, naturally increase rather than decrease Delta activity when trying to focus. The inappropriate Delta response often severely restricts the ability to focus and maintain attention. It is as if the brain is locked into a perpetual drowsy state”. This extract… Read more »
While visual entrainment is more powerful than audio alone for inducing desired brainwave states, more caution is needed when using visual methods. Between 0.3 and 3 percent of the population is susceptible to having seizures from flickering light stimulation, and for other people, flickering visual stimuli simply makes them uncomfortable. People with epilepsy have a greater chance of having a seizure from exposure to flickering light stimulation.
That is a general assumption people make but there isn’t really much science to back it up. What we do know though is that isochronic tones are ineffective below 4hz, and possibly a bit higher. So for theta and delta entrainment you are best off with binaural beats. In my experience binaural beats will be very effective all the way up to around 40hz.
The phenomena of brainwave entrainment was first described in the scientific literature in 1973 by Gerald Oster in results published in an article in Scientific American entitled, “Auditory Beats in the Brain”. He showed that a specific brainwave could be induced when a person heard two separate, but closely related, sound frequencies, one in each ear. He discovered that when the frequencies heard by each ear differed by about 10 hertz, the brainwave pattern of the person hearing the sound would synchronize to the difference between the two frequencies. For example, if the person heard a 410 hertz sound in one ear and a 400 hertz sound in the other ear, their brainwaves would stabilize at the difference between the two, or 10 hertz. This technique is called binaural beats, and it is a fundamental principle of brainwave entrainment methods.

These are lower frequency waves: The state is generated when our thoughts are really not concentrated and our minds wander freely, or we are in a relaxed state such as meditating or daydreaming. We also experience Alpha Brainwaves when we are gently busy with routine tasks like pottering in the garden, taking a shower, putting on makeup, doing light housework. Alpha is considered to be the bridge between the conscious mind and the subconscious mind.

“A quite different phenomenon results when stereophonic earphones are used and the signals are applied separately to each ear. Under the right circumstances beats can be perceived, but they are of an entirely different character. They are called binaural beats. . . . Binaural beats require the combined action of both ears. They exist as a consequence of the interaction of perceptions within the brain.”
I’ve been on the brainwave vibe for about 6 months now, & I’m really diggin’ some results! I find that there are certain frequencies, I guess, that feel right and comfortable to my mind; I also find that I can physically feel the area of my brain that “pure” (no frikkn ocean waves) tones are affecting as I listen to them. This occurs the moment I hear the sound. Kinda like energy, a brain tickle. Spooky & awesome!!
A study that tested photic stimulation for reduction of poor behavior in ADHD children found that 15 sessions of photic stimulation between 12 Hz and 14 Hz resulted in behavioral change. This behavioral change was measured using the Achenbach Child Behavior Checklist – which accounted for not only the parent’s perspective, but self-reports from the children. Statistically it was stated that behavior improved up to 70% in the stimulation group compared to controls.
We all experience different states of mind each day: states such as sleep, focus, or creativity, for example. Every state of mind has a unique electrical signature that can be detected in the brain. These signatures are known as “brainwaves.” Using specialized equipment, these waves (or frequencies) can be measured and recorded, allowing us to map what brainwaves are present during certain key states of mind.
Back in 1839, Dr. Heinrich Wilhelm Dove, a Prussian physicist and meteorologist, discovered that when you introduce tones with certain frequencies into each ear, you could actually entrain the electrical patterns within the brain to resonate in very specific patterns, called brainwave states. The last two decades have seen an amazing amount of scientific interest in this world transforming field of study, laying the foundation for the hundreds of studies conducted since then, boosting the technology’s significance and importance immeasurably.

If the further development of consciousness and awareness is your ultimate goal, there really is no substitute for actual meditation, of which many techniques are the result of thousands of years of human endeavor and accumulated knowledge and experience. Sure, it's not as easy as putting on headphones and pushing a button, but achieving authentic inner peace and relief from the stresses of human existence will mean so much more to you when earned through the time-tested route of traditional meditation. (Plus, once you learn to actually meditate, you can do it anywhere anytime without having to rely on being plugged in to something!)
Holosync is often seen as the ‘gold standard’ of brainwave entrainment. The Holosync program features 13 different levels which are listened to for 4-6 months before your brain will have adjusted enough to the technology to be able to move on to the next level up. Starting at level 2 of the program, Holosync goes the extra mile by incorporating your own chosen positive affirmations – recorded in your own voice.
My name is ******. I’m a systems engineer which have worked on the engineering field for over 20 years. During the last few years I have faced some personal challenges which have put a lot of my abilities to a test. Over a year now I got the “Equisync II” CDs from the EOC Institute, and the results from the very beginning were really amazing. Even as an engineer it was not easy to understand the incredible benefits of this brainwaves therapy when used consistently.
Going back to the technology, the simple claim of brainwave entrainment is that, by listening to these audios, usually with stereo headphones and eyes closed, your brain will be naturally and effortlessly led into a specific brainwave state as designated by the maker of the audio (ie: it could be alpha, theta, delta, gamma, etc., depending on what the audio is designed to do.)  The other most basic claim is that when listening to these audios, the right and left hemispheres of the brain synchronize and you experience whole-brain functioning.
One RCT (n=108) showed significant reduction in anxiety from a single session of alpha/delta therapy for day surgery patients. A crossover RCT of a single session of theta stimulation in four healthy adults reported significant improvement from the intervention in one of five measures. Five pre/post studies reported significant benefit from the intervention for 16 of 27 outcomes.
