Another study found slight improvements in trait anxiety as a result of entrainment. It was noted that the study with the most successful protocol started at 30 Hz beta and ramped the frequency down until the person experienced relaxation for 15 minutes. This was then followed with a session of 8 Hz to 14 Hz for 7 minutes. The results suggested that 75% of individuals improved on their measures of long-term stress.
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.
Isochronic tones work just the same in delta as they do in alpha, theta and beta and they are widely used in the brainwave entrainment community to help people sleep. Like you, I’ve also seen some websites saying they don’t work in delta, but it’s a bit like the game of Chinese Whispers, where someone makes a comment and then after it gets passed around and shared a lot the message gets distorted and appears to be a fact. I don’t know of any scientific reason why they wouldn’t work in delta. I remember some people talking about this on a brainwave entrainment forum many years ago. They were saying they found isochronic tones a bit too abrupt for using to help them sleep and they preferred binaural beats, as they thought they were a more soothing sound. That was just a personal preference shared by a couple of prominent forum members at the time and some people then took that as a fact for everyone. That’s where I think that belief originated from.
I’ve been using equisync first thing in the morning after I get up, and listen to all three tracks in a row. I again listen to all three tracks in the late afternoon. If I don’t have that much time available, I will start on Track 2 or 3, as necessary. I have really started to focus on my breathing, and notice the difference – I finish the session in a DEEPLY relaxed state.

To further illustrate how brainwave entrainment enhances your meditation practice, here is an explanation. When an experienced and advanced meditator is hooked into equipment that reads their brainwave patterns, it is most common for their brain to move from whatever state they are in before they meditate (normally a Beta or higher Alpha state) slowly down into a deep Theta rhythm.  Very advanced meditators are able to bring their brain all the way into a Delta state, which is most normally where deep sleep occurs.  To be able to bring the brain into these deep brainwave states through the process of meditation can take years of meditative practice, and lots of discipline.


However, if you are looking to do something more practical, like improve your mental sharpness, overcome attention issues, succeed at work, be more productive, you may want audios that target more of the alpha and beta ranges, and are created to put you in peak performance states of mind. In this case, a program like our Effortless Overachiever Bundle would be much more practical and helpful for you.
Just my FIRST session I felt like I successfully achieved a theta state of meditation….I came out of it feeling extraordinarily renewed and with this profound insight of “everything is going to be ok”….this was all from my FIRST session. I cant wait to continue this on a regular basis to see where it leads….one day I hope to achieve the deeper delta states…
The objectives and inclusion criteria of the review were clear. Relevant sources were searched for studies, although the restriction to published studies in English meant that the review was prone to publication and language biases. The authors did not state whether steps were taken to minimise the risk of bias and error in the processes of study selection and data extraction (for example, by having more than one reviewer independently make decisions). The authors mentioned which studies were blinded, but it did not appear that study validity was systematically assessed, which made it difficult to judge the reliability of the review findings. The decision to combine studies by narrative synthesis appeared appropriate given the strong clinical heterogeneity between the studies, but the authors failed to quantify the size or statistical significance of the findings reported. The evidence presented appeared to justify the authors’ conclusions that further research was justified, but in view of the dearth of good-quality evidence and problems with methodology and reporting in the review, the conclusions regarding efficacy did not appear reliable.

[…] We are fortunate in this day and age to have technology available to us that effortlessly leads the brain into deep meditation, through a scientific process called the ”frequency following response”.  This amazing technology, most commonly called brainwave entrainment, substantially enhances the meditative process, and allows people in their very first session to reach brainwave states that would otherwise take several years to reach through traditional meditation techniques.  This means that you can start reaping the powerful benefits of meditation quickly, and without having to exercise your “discipline muscle” at all!  If you are interested- learn more about brainwave entrainment.

Thank you for the info. I must add that the Yoga Nidra state is the state in which a person can be in Delta but fully conscious. I did experience this state accidentally 3x in 2yrs after discovering Swami Rama’s teachings about the state&1 of the techniques for it(only 4 seems to exist & are practiced in monasteries at the time,according to him. He was the yogi who 1st demonstrated the 4 states,fully aware of himself & his surroundings, under lab conditions).

Yes, brainwave entrainment is based upon science. It has been scientifically proven to work, and to benefit the brain in all kinds of amazing ways. Yes people use things like EEG machines to read how it works on the brain. BUT, this does not mean it is overly complicated, and it does not mean that you have to be overly techy or scientific, or have any experience in neurology at all to create a brainwave entrainment audio or understand how it works.
a concise P.S. I was in a horrible car accident when I was 18 and had to learn to read and write and walk and talk all over again. It was long ago and I’m pretty well over it, but such an injury has lifetime repercussions. The neurological damage sustained causes my left arm to shake uncontrollably anytime I use it in a situation requiring precise coordination. From simply listening to the demo, the shake [though not disappearing completely in the last 2 months] has lessened dramatically. I had been wondering for years what kind of neurological exercises I could undergo to help it…
Many people experienced in using alpha brainwave entrainment report that the state of mind associated with alpha waves is a time when they feel most consciously connected to their subconscious mind. The intense experience of hypnagogic sleep, reported by some people as a feeling of being awake and asleep at the same time, is also associated with alpha brainwaves.

Thanks for your compliment on my article. 🙂 There are some frequency lists which reference and quote some links to metabolism, but I don’t know how effective or reliable that information is. One of the good things but also a drawback of this technology is how accessible it is to use and create tracks. That makes it unattractive for big companies to invest in large-scale research because it’s hard to patent and protect any product they produce based on the research. As soon as they released the frequency data, people like me would produce free videos and cheap MP3s to utilise the research, so they wouldn’t be able to get a good return on their research investment. So to try and gain some insight into what is working for people, at the moment, we are relying upon assessing anecdotal feedback in many areas. Before buying any products/tracks for increasing metabolism, I would look for and try out free videos on YouTube first, to try and gauge how those particular tracks and frequencies work for you.
Discovered by Austrian Psychiatrist Hans Berger in 1908, Alpha brainwaves cycle 8 to 13 times per second, a good bit slower than beta brainwaves. While considered a part of a group of brainwaves, the Alpha brainwave has one distinct trait that makes it stand out from its siblings – it appears and disappears while going through our brain. Sometimes alpha waves are present, sometimes they are not. The disappearance of the Alpha brainwave usually occurs when someone is asleep or experiences heightened emotions such as fear or anger. This brainwave only appears whenever a person is awake and relaxed, a one-of-a-kind distinction among other types of brainwaves. 

I have seen 1.5Hz being linked to HGH, but also 4 or 5 other frequencies as well, so it’s difficult to know what may work if any. I haven’t seen any research relating to HGH and brainwave entrainment. It’s widely believed that 40Hz is the limit for achieving a brainwave entrainment effect, which is also where many believe the gamma frequency range begins. Once you get over 40Hz into gamma your brainwave activity isn’t likely to stay in sync with it. So from a brainwave entrainment perspective, I recommend high beta frequencies for increasing energy during workouts.

It is important to take an objective look at published scientific evidence to determine whether brainwave entrainment is an effective treatment for certain conditions and/or symptoms. Most preliminary evidence suggests that while the technology will not cure any condition, it may be a successful adjunct treatment when used carefully with the proper protocol.

By exposing an individual to repeatedly external stimulus which can be flashing lights and/or recurring sounds, the entrainment process consists in pushing the brain to adjust to match the frequency provided. Unlike other forms of neurotherapy which require the individual to actively respond to stimulus, entrainment creates an immediate neurophysical response which is instinctive and effortless for the person being provided with the light and/or sound combinations. The key outcome of the sensory stimulation is known as the ‘Frequency Following Response’.
I can offer a hypothetical--however do not know know practical it will turn out to be. There is a fair amonut of bad science on this topic on you tube. The gamma wave frequency is associated with attentional focus and arguably a unified sense of self. If it could be entrained it should lead to a meditative focus-like exceptionally well-trained meditators. Some but not all studies on meditating Buddhist monks suggest this is so. Does this really and more generally occur--I will say there is nothing lost in trying--we all go into a 40Hz range on occasion without ill effect-- but I would not put confidence in the purported methods out there at present. Good luck.
Robert Monroe, a radio producer and executive published a popular book called Journeys Out of the Body about his out-of-body experiences when using brainwave entrainment. He later founded an original brainwave entrainment audio company, Hemi Sync. In 1981, the book Mega Brain by Michael Hutchison brought brainwave entrainment information, techniques, and terminology into the popular press.
With brain wave entrainment technology, changing brain wave states is an instantaneous and effortless process. The 'periodic stimulus' can be sound, vibrations and/or light. We have found that we get the best results with blinking lights which are experienced through closed eyelids. This is only problematic for people with existing diagnosis of photo-induced epilepsy, as blinking lights can induce a seizure in them. The programs are enhanced with Deepak Chopra doing the narration along with holographic sound effects and original music composed and performed by Rudy Tanzi.
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.
Because the mind and body are a single system, changing our brainwaves and spending more time in harmonious, relaxed, and restorative mind-states also affects our physical health. Physical health then reinforces our mental-state, and a feedback loop of either positive or negative processes becomes established. Research studies have shown beneficial effects of using brainwave entrainment for treating migraine headaches, premenstrual syndrome, and for managing physical pain.
Slower still are theta waves. Theta is best known as the brain wave state of dreaming sleep, but it is also associated with a number of other beneficial states, including increased creativity, some kinds of superlearning, increased memory abilities, visionary experiences, and what are called integrative experiences (where we make broadly-based positive changes in the way we see ourselves, others, or certain life situations).
Are you someone who has turned to meditation or yoga as a way of relieving stress and improving your overall well-being? Yoga and meditation are time-proven methods, used for centuries, which restore mental, physical, and spiritual balance in people’s lives, and brainwave entrainment can be used in conjunction with these practices for even deeper levels of benefit. 
While the physiological and psychological processes being uncovered by brain science in the study of brainwaves is sometimes complex and still being investigated, certain basic principles are well-established, easily understood, and helpful for achieving the most effectively use of brainwave entrainment when seeking relaxation, improved sleep, lowering of anxiety, or other goals. This important background information and scientific knowledge presented here includes: 
I have spending time in a floatation tank for the last 9months and just recently added the audio of crystal bowls into the tank. HOLY FLOAT! If you have experienced the bowls live then you know the physical experience that they produce; aside from the meditative side. Well, this effect is accentuated 10fold while in the tank. I have also started to float with binural entrainment audio and have seen a few effects.
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. To learn more see this article about brainwaves in Scientific American.
“…humans have always been intrigued by the possibilities for influencing mental functioning that emerge from combining rhythmic sound and rhythmic light stimulation. Ancient rituals for entering trance states often involved both rhythmic sounds in the form of drum beats, clapping, or chanting and flickering lights produced by candles, torches, bonfires, or long lines of human bodies passing before the fire and chopping the light into mesmerizing rhythmic flashes. From Greek plays to Western opera, our most popular entertainment forms have made use of combinations of lights and sounds. Some composers, such as the visionary Scriabin, actually created music intended to be experienced in combination with rhythmic light displays.”
Given that brainwaves control and connect such a vast range of human experience from thought to feelings to actions, it is easy to see how the deliberate control of brainwaves can affect mood, behaviors, motivation, and even physical health. Brainwave entrainment is a safe, simple, and scientifically proven method for quickly guiding the brain into a beneficial brainwave frequency to facilitate healthy sleep, lower stress, heal emotional problems, and improve physical health.
-Other Specialized Entrainment Methods: There are a few other things to consider like whether the audio creator uses binaural beats, monaural beats, or isochronic tones when appropriate for the desired effect of the audio. Or whether they use other entrainment methods as well, like volume modulation, pitch modulation, or panning from right to left of the headphones to further improve the immersion of the audio.
Only 4 of the participants reported no change as a result of the stimulation. Four years later in a study (1989) by Anderson analyzed LED photic stimulation for the treatment of headaches. There were 60 patients included in the study which involved Variable Frequency Photo-stimulation (VFP) with specialized goggles that contained light-emitting diodes.

A popular opinion in the brainwave entrainment community is that listening to isochronic tones without music produces a much stronger effect.  However, in the study by Doherty, Cormac. “A comparison of alpha brainwave entrainment, with and without musical accompaniment” (2014),  it was concluded that brainwave entrainment was equally effective for isochronic tones, both with and without music.
