How brainwave entrainment works is quite simple. A tone or beat is overlayed into a track (usually with nature sounds or calming music) that pulses on and off at a specific rate. The frequency of that rate is matched by the brain, thus leading it to produce brainwaves that correspond with that particular frequency. The specific frequency range determines the brainwave produced (ie: alpha, theta, delta, gamma). For example, if the beat is pulsing on or off at a rate of 7hz, your brain will produce brainwaves at the frequency of 7hz, which are theta waves.

So my question is: Why? When I read it, I had a bit of a fear of brain aneurysms. Therefore, 1. could someone contact me to tell me why use of your product shouldn’t continue past 2 hours? [I probably won’t heed the reason unless it’s a life or death warning: I love this product that much!] 2. Please feel free to post my letter in your testimonials, if you ever decide to post such customer comments.
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.
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.

Deep relaxation is a major benefit resulting from the brain’s cortical frequency following response. By selecting the desired rate the brain, via the frequency following response, will tend to mimic the rate it is exposed to and thus enter that brainwave state. This helps to explain why this technology can produce benefits commonly found with meditation. One of the most valuable benefits of consistent  brainwave entrainment is that we are able to experience and recognize the various states of consciousness. With practice we can learn how to re-create these states.
"I have been using Quantum Mind Power for two weeks and today I feel that although the changes are subtle, I have been able to overcome many roadblocks in my personal life. I have ADHD and have been taking Adderall for 7 years, recently I decided that I need to stop and have cut my dosage in half with the intention of completely stopping within a month.  I have also just started teaching Pilates as a second job.....
Don’t let someone fool you by making this sound overly technical, scientific, or too good to be true. It can truly change your life! It changed mine in a huge way. That’s why I’m so passionate about it! But it isn’t a “magic pill” that will effortlessly solve all your problems. I truly think this technology is nothing short of a miracle, and is on the very edge of the future in scientific ways to influence consciousness, personal development, and success in life, but it is also still practical, and worth exercising some discrimination and skepticism when making a decision on where to spend your money.

I have purchased several brain entrainment CDs, all of which have cost far more than the one I am using from the EOC Institute. Without a doubt, your CD outperforms the other ones hands down. It is nice to know that there are companies out there that truly put the customer first instead of the “ALMIGHTY DOLLAR” Thank you so much for your excellent product. It is a big help.

I definitely NEED (& can feel a difference mentally) Gamma the most. Beta and Alpha do better my processing. Theta waves are TERRIBLE! My normal symptoms increase when listening to those frequencies! Delta has been helpful for me around nighttime. It has helped my sleep on occasion. *Note: Do not listen to higher frequencies (Gamma, Beta) before bedtime! They will keep you very alert.


Altered states of consciousness: In as early as 1987 it was discovered that photic stimulation at specific frequencies produced an altered state of consciousness. An extremely small study with just 4 individuals involved photic stimulation at 6 Hz, 10 Hz, and 18 Hz. The results were reported to have altered their conscious awareness. This really isn’t that surprising to anyone that’s used brainwave entrainment therapy.
Miscellaneous reports have also been made about the advantages of brainwave entrainment with the reviews of numerous users stating that the it can assist in increasing sex drive. Research shows that relaxation, meditation, and good self esteem ensures normal body functions. Furthermore, the brainwave entertainment allows your body to flow in rhythm with the beats therefore if your brain accepts and blends with certain frequencies, this could account for the enhanced sex drive.

I would like to start off by saying that many bold statements are made about this technology from people who have a self-interest in promoting or rejecting it. We have to face the truth by accepting that people are profiting from brainwave entrainment, and as a result of this other groups of people are being affected in a negative way (from a business point of view). This is a reason why you can find all kinds of claims from someone who has never used or tested the technology.  Unfortunately I have found in my own personal journey of using brainwave entrainment that there are some great people out there making some great products, and there are also some irresponsible and untrustworthy people out there trying to grab a slice of the pie.
Beta stimulation: There is evidence that stimulation within the beta range can improve attention, measures of intelligence, relieve short-term stress, decrease headaches, and decrease behavioral problems. Some evidence even suggests that beta could decrease emotion-based exhaustion. Many people with slower frequency brain waves may benefit from regular beta stimulation.

From a brainwave entrainment effectiveness perspective, it’s my understanding that the response from isochronic tones stimulation starts to diminish over 30Hz and that 40Hz is about the limit for using them. So from what I’ve read on the topic a 100Hz beat wouldn’t work, probably because it’s too fast for the brain to process and synchronise with it.
Normally, binaural beats, isochronic tones, or monaural tones have a certain level of capacity to entrain neural activity—and then they bottom out. By combining really great entrainment tools, I wanted to create a better entrainment stimulus that could entrain more neural activity quicker, allowing us to go deeper much more quickly than we have ever been able to go before, and moving our meditation practice or spiritual development to the next level.
According to both observation and research, after a series of brainwave entrainment practices, the brain learns how to state change. This enables you to achieve certain brainwave effects in the absence of entertainment. Additionally, research shows that children are usually in the Theta stage and this in itself could provide a detailed explanation for their ability to learn fast and remember what they have learned. We can take advantage of this effect and use Alpha and Theta waves to reduce learning time in adults.
Alpha brainwaves are resonating just below beta brainwaves at the frequency range of 8Hz to 12Hz on an EEG. Beta brainwaves are the normal, waking life, active, rational thinking and problem solving brainwaves that are dominant in most people throughout the day. Alpha brainwaves begin to show up when relaxation occurs. Often times the simple act of closing your eyes can product spurts of alpha waves. Taking a few deep breaths or consciously relaxing will do the same. When alpha waves become dominant, the body and mind are usually comfortably relaxed.
So, what is binaural beats or binaural tones?  They are auditory (hearing) processing artifacts, or apparent sounds, caused by specific physical stimuli.  This effect was discovered in 1839 by Heinrich Wilhelm Dove and earned greater public awareness in the late 20th century based on claims coming from the alternative medicine community that binaural beats could help induce relaxation, meditation, creativity and other desirable mental states. The effect on the brainwaves depends on the difference in frequencies of each tone: for example, if 300 Hz was played in one ear and 310 in the other, then the binaural beat would have a frequency of 10 Hz.

I have been making relaxation recordings for mental self help and health improvement since 1979. As a pathfinder in EEG ( brainwave monitoring and entrainment ) I understand totally the effects of sound and music on the human mind and body. The recordings offered from your website are without doubt some of the most effective I have ever used and recommend them to my clients whole heartedly
Use traditional meditation to create the changes in the brain that lead to the benefits I’ve described here. Of course that means going through a long learning curve while you master the art of meditation, motivating yourself to sit each day to meditate. And, to get the benefits I’ve described, you’ll need to meditate several hours each day), and continue in that way for 30+ years.
All brainwave frequencies are useful and beneficial at certain times – there is no brainwave that is intrinsically better than another. However, by deliberately choosing to attain a particular brainwave state, a corresponding mental state can be brought about at the same time. For example, a working person who has been in an overly alert beta brainwave pattern for many hours can quickly shift their mind and body into a relaxed state by listening to a few minutes of brainwave entrainment music for inducing alpha or theta brainwaves.

Clinical testing of Brain Sync programs resulted in a record-breaking 87% success rate. They are offered to patients at America's most prestigious hospitals such as Sloan Kettering and Dana Farber Institutes. EEG studies conducted at Harvard Body Mind Medical School, and UCLA concluded that Kelly Howell's Brain Wave Audio Technology® prompts brain activity into extraordinary body-mind states. Vist our Research Findings page for a full list of articles from the Harvard Medical School, the U.S. National Institutes of Health and Psychology Today that concur: the benefits of guided meditation, binaural beats, brainwave entrainment and positive subliminal messaging are real and profound.

3) Theta waves – these waves exist between 4 and 7 Hz. This state is commonly referred to as the dream or “twilight” state. Theta is associated with learning, memory, REM sleep and dreaming. Memory development is also enhanced while in this state. When in a theta brainwave state, memory is improved (especially long-term memory), and access to unconscious material, insights and creative ideas is increased.
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!!
Scalar waves are a constantly regenerating energy source that imprint a signature on your body with lasting positive effects. They strengthen chemical bonds within DNA, making it more resistant to damage and cleanse blood and cells to improve immune function. They impart energy that helps mental focus, and increase amplitude of all EEG frequencies, but particularly the lower levels where deep rejuvenation, relaxation and healing occur. They leave you feeling refreshed and energized, with lasting pleasant sensations that continue long after each brainwave entrainment session.

First discovered by biophysicist Gerald Oster at Mount Sinai Hospital in New York City, Brainwave Therapy sends pure, precisely tuned sound waves of different frequencies to your brain via stereo headphones. In his EEG research, Oster discovered that when different vibrations, or sound frequencies, are delivered to the brain separately through each ear (as with stereo headphones), the two hemispheres of the brain function together to "hear" not the external sound signals, but a third phantom signal. This signal is called a binaural beat, and it pulses at the exact mathematical difference between the two actual tones. For example, a signal of 100 Hz delivered to the left ear, and a signal of 107 Hz delivered to the right creates a binaural beat of 7 Hz that in this case falls into the Alpha range

When delta waves are present, our awareness of the external world decreases and shuts off. People with ADD have problems with delta waves occurring when they are trying to focus, and focus and attention become increasingly impossible with stronger delta waves. Studies show a reduction of anxiety, improvements in insomnia, and elimination of headaches when people engage in sessions of delta brainwave entrainment.

Binaural beats can be experienced in any float session you book.  To this point in your floating practice you may, or may not, have heard of – or perhaps already experienced – binaural beats and their effective use of being a unique option/tool to listen to while in (or out of) the tank. But what exactly are binaural beats, how do they work and why choose to listen to them? All good questions, so here we go:

There are many advantages and disadvantages with binaural beats. One of the major advantages is hemispheric synchronization. Since both hemispheres are required to create the beat within the brain, this method is an excellent way to create greater harmony between areas of the mind typically functioning independently. Binaural beats are also known to have effective hypnotic and relaxing effects.
All brainwave states serve important mental functions, and with today’s lifestyle, returning to a peaceful way of being is becoming increasingly difficult to achieve and maintain for any period of time. This continual stress or alerted state causes disease in the mind and body, which is why it’s paramount for us to relearn or retrain ourselves to get back to these healthful and rejuvenating states.
The main gist of brainwave entrainment audios, without getting too technical here, is that they effortlessly guide one’s brain (when listened to with stereo headphones) into a specifically targeted state, as designated by the creator of the audio. They are able to alter your brainwave states through the use of specific audio frequencies, and specific beats-the most common of which being binaural beats (though there are other types of beats being used as well).  When one frequency is played into one ear- let’s say 1115 Hz- and a slightly different frequency is played into the other-say 1125 Hz- the brain is forced to reconcile the two, and creates its own “phantom” frequency that is the difference between the two- in this case 10 Hz.  Not only does this allow the brain to be led into specific brainwave states, but it also allows the two hemispheres of the brain to synchronize with each other, stimulating and promoting whole-brain functioning.

Thanks for the coupons, I had originally looked into these cd’s after my doctor recommended them, but my mom wound up buying them for me for Christmas (she didn’t know about the coupons I had!) Anyway just listened to Equisync II today for the first time, I was in such a state as to where I didn’t know if I’d fallen asleep or not! I hadn’t but was in such an amazing place.

With almost 100 years of research validating the effectiveness of brainwave entrainment, it’s no wonder why it’s used by thousands of people all over the world. What does the future entail in this exciting field? With the adoption of smartphones, virtual and augmented reality, and advancements in technology reducing the cost of EEG and other forms of biofeedback devices, the entrainment possibilities are endless.

Anyone who has sought out different methods for enhancing cognitive ability will probably have come across a technique known as Brainwave Entrainment. However, it is a fairly niche area of brain training, meaning that this form of stimulation is often overlooked in favour of more mainstream methods. The following outlines what Brainwave Entrainment actually is, how it is used, and some of the benefits attributed to it.

That is very interesting to hear. I have also been an avid user of Holosync for long periods of my life. Were you progressing through the levels? I do know that Holosync in particular is designed for each level to push the brain to grow a “tolerance” to its effects. Once this happens the brain and nervous system has reached a new level of resiliency and is ready for the next level of the program, where the carrier frequencies are lower and more profound effects begin again. Was this the case for you? If Holosync was not your bag, you may also consider trying out some of the newer brainwave entrainment products with isochronic tones and monaural beats (holosync only uses binaural beats) as many have reported that they work better for them.
Really great stuff here, man. Well done! Without taking anything away from the article it would have been great to have under one “roof” similar information about hypnotherapy and subliminals. I invested quite a lot in buying binaural cd’s but after reading your material I think that for short term effects isochronic tones rather than binaurals are the technology to go for now. For longer lasting and possibly permanent effects I’m not sure whether I should go for hypnosis or subliminals (or both). An article as well written and comprehensive as yours but focusing on hypnosis vs subliminals would have completed the circle for me. The stuff I’ve read so far on binaurals vs isochronics hasn’t really done it for me. Any chance you could give it a shot?
