The reported PMS symptoms that improved included: affective lability, anxiety, appetite changes, bloating, breast tenderness, concentration difficulties, depression, fatigue, and irritability. Researchers noted that there was a clear “trend” toward a reduction in social withdrawal as a result of symptoms as well. A total of 49/50 women reported improvements.
Hi Et, In all the feedback and studies I’ve read and looked into over the years, I’ve seen lots of feedback from people talking about how they don’t like the sound of the tones, or they find them irritating in some way. Unfortunately, there doesn’t seem to be any particular reason why one person likes it and the next doesn’t. It’s a bit like normal music, one person’s sweet symphony is another person pneumatic drill. It’s common for people to find it weird and maybe annoying at first, which is how I felt in the beginning. But usually after a few listens you can start to get used to it and appreciate the sound, and especially the feeling it gives you. Personally, I think it can help if you try to embrace the sound, psychologically speaking beforehand. It can also help to have the sound playing at a very low volume, to begin with, then building it up as you get more used to it.
Recent research at the University of Lisbon finally uncovered the reason for the 350 year-old mystery, finding that the resonance of sound is the mechanism for entrainment of swinging pendulums and ticking clocks, and it seems likely that the energy transferred by sound is also responsible for other observations of entrainment, including brainwave entrainment.
AVE is capable of producing situationally appropriate brain wave frequencies through the process of entrainment (the tendency of physiological processes to mirror environmental stimuli). AVE also increases cerebral blood flow (blood flow in the brain) and increases the metabolization of glucose in the brain for improved functioning of the neurons. The combined outcome of these processes is improved mental performance. It is an effective, inexpensive alternative therapy for many disorders such as anxiety, Attention Deficit Disorder (ADD), Seasonal Affective Disorder (SAD), PTSD, Fibromyalgia and chronic pain. Our AVE devices are also used successfully to boost physical performance for athletes, academic performance for students and cognitive performance for seniors.
After one month of using Equisync, I feel relaxed, calm and not stressed at all, despite that I am leaving my present job soon for an early retirement, I handle the situation very well. I have the feeling that I’m going to be ok and there is nothing to worry about. This is what I have gained so far from using Equisync and it’s really meaningful in the erratic world that we live in.

  There’s an added bonus feature you get with the Brain Evolution System™: scientific studies indicate that brainwave entrainment can not only enhance normal thinking to higher levels, but can also act as a “mood enhancer” to alleviate depression, chronic fatigue, and related conditions – as well as the physical symptoms brought on my too much stress.
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.
Alpha (12hz – 8hz) – Awake, but deeply relaxed. Simply closing your eyes will produce alpha brainwaves. This category is associated with daydreaming, visualization, imagination, light meditation. Brainwave expert Anna Wise called the alpha range the bridge between beta and theta. (More information can be found in Wise’ book The High-Performance Mind)
In physics, entrainment is the process of two oscillating systems coming to assume the same periodic rhythm, such as is observed when two clocks slowly synchronize their ticking and tick together in harmony after some time. Pendulums also achieve this same synchronicity when swinging in close proximity to one another, a phenomenon first observed and written about in 1665 by Christiaan Huygens, a Dutch scientist.
Was wondering if you could give me a little more background on the suggested 2hr usage limit. I’m in LOVE with these CDs. Spent two months 2-3 times per day with ‘Equisync II’, and earlier this week shifted over to ‘Equisync III’. Since moving into Equisync III, I’m naturally drawn in my morning sitting to about 1 1/2 hrs with the tracks looping through my iPod. Then I sit again at night. I feel great. So is the 2hrs suggested for people with little prior meditative experience, is it a precaution for those whose psyche may be more fragile and prone to getting uber spacey and not managing their lives?
But especially at this point, I’m on a mission to get as many people using Holosync® as I possibly can—my current goal is 100 million Holosync® users. Because we already have so many people using it, the economy of scale allows me to offer it to you for MUCH less than what my accountant suggested: just $179 if you’d like Awakening PrologueTM on CDs… or $159 if you want the downloadable MP3 version…
With so many thoughts begging for your attention each day, it’s hard to believe that most of them are the same ones you had yesterday. Actually, many psychologists who have studied the thought processes associated with our thinking patterns would agree that, on average, 90% of the thoughts that we become aware of throughout the day are the same thoughts that we have already experienced, over and over again. The reason we are so prone to repetitive thinking is because the brain is always … [Read more...]
Not only do certain brain wave rhythms get strengthened as a result of entrainment, but a dominant frequency band results in a different state of awareness. Those that have used a quality brainwave entrainment product can vouch for the fact that their perception is altered by their brain waves. Not only could this be due to brainwave changes, but it may be a result of increased interhemispheric communication.

Controlled or pre/post studies of the effects of BWE using auditory or visual stimulation were eligible for inclusion, provided pulses of light or tone were delivered at frequencies hypothesised to have a beneficial effect or in line with a protocol addressing clinical outcomes. Studies were required to report clinical or psychological outcomes (measured using standard methods or as deemed appropriate by peer review) and to report statistical analysis. Studies of outcomes such as electroencephalogram (EEG) response or neurotransmitter levels were not eligible. Case studies were excluded.
I love your tapes! I bought them a few weeks ago and have greatly benefited. I’m also a holistic practitioner and have recommended them to a number of patients. And today when I made my last referral to your website for them to purchase from, it occurred to me that perhaps you have referral discounts, or wholesale prices for practitioners, and that I should ask?
Hi there! This is a great question. I think the most important thing to first understand is that in spite of the circumstances you are facing, your stress level and the way you feel on a day to day basis is still within your hands. Happy people are not happy because they have less stressors or challenges in their lives, they are happy because they have learned how to be happy in spite of these challenges. At the same time there may be action you can take to minimize these issues you are facing as well.
I appreciate your compliment on my article Henry. I’ve been using and reading up on isochronic tones and brainwave entrainment for many years, so it was just a case of trying to put a lot of what I’ve learnt into one article. I don’t have a great deal of knowledge or experience in using hypnosis and subliminals, so I’m afraid I wouldn’t be in a position to create something so extensive in reviewing them.
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.

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.

Because the brain filters and interprets reality in a split-brained way, we tend to see things as separate and opposed, rather than as connected and part of the oneness spoken of by the great spiritual teachers (and, in the last few decades, by quantum mechanical physicists). Thus, at a deep level, the dual structure of our brain, in conjunction with brain lateralization, predisposes us to see and experience ourselves as separate from, and often in opposition to, the rest of the world—instead of experiencing the elegant interconnectedness between us and everything else. Our childhood associations and programming build on this inborn tendency by training us to seek this and avoid that, to move toward pleasure and away from pain, to do good and not bad, and so on. The greater the lateralization in the brain, the greater the feelings of separation—and the greater the feelings of separation, the greater the fear, stress, anxiety, and isolation.
If you're struggling to focus and feeling a bit tired and unmotivated while studying, you can help boost your concentration and energy levels by increasing Beta activity.  The SMR range is right at the bottom of the Beta range, so it's not too intense, and so is ideal for playing in the background and using as a general study aid.  If you are looking for something a bit higher for a more intense focus session, try my Study Focus isochronic tones session, which uses frequencies between 14-17Hz.

Learning: Since performance improves among those with ADHD and cognitive function may be boosted, one may hypothesize that learning would also improve. Those that are struggling to learn as a result of inattentiveness may benefit from stimulation with beta frequencies. Deficits in learning tend to be associated with abnormal or excess slow wave frequencies.
Thanks, this was the kind of article I was looking for. I most have gotten over excited as I read a post about a guy who had major success with 40hz binaural beats. I wanted to make my own experiment, but I see now that I will need to continue my research and gather more background information. Maybe one should have his physiology examined? In order to have a professional opinion on whether or not it will be altered or damaged by use of brainwave entrainment (Maybe you happen to be a very vulnerable individual). Getting trustworthy guidance from an experienced source would also be nice 🙂

EquiSync’s design is based on the 100’s of studies performed on the effectiveness of brainwave entrainment technology, and 1000’s of studies on the powerful benefits of meditation. If you are interested in better understanding the power of this technology and rapidly expanding field of research, then here is a very abbreviated bibliography, a very small sample of the studies out there:


I also believe that the dangers of brainwave entrainment should be further explored as well. There are relatively vague benefits, but it remains unclear as to whether entraining certain frequencies may be detrimental to performance or induce harm. Despite the fact that brainwave entrainment has existed for a long term, it remains an understudied niche in neuroscience.
We’ll use Holosync® to place you in an alpha brain wave pattern, that of focus, concentration, and accelerated learning. You’ll become completely absorbed in whatever you’re reading—or, for that matter, in anything you do requiring focus and concentration. And, you’ll remain refreshed even after hours of concentration. Quietude™ will dramatically increase your productivity and learning ability.
I am one of the fortunate ones who received a free demo of your product. I do believe your product corrected damage to my brain from a childhood concussion. Immediately upon use, I became aware of sounds, drainage and even discomfort behind my right eye and the lower right side of my skull. This continued for a week of using the product daily. I was about to give up using the product when all discomfort stopped, and has not returned. I do believe your product should be used for childhood head trauma. Even though the brain is only bruised, a life can be altered immensely. I love my Equisync II and will use it daily and with confidence.

Anxiety: In a review of brainwave entrainment research, there were several studies that investigated short-term stress relief as well as long-term stress or “burnout.” Several used modalities of auditory stimulation, while a couple used audio-visual entrainment. Those with heightened short-term stress and anxiety were undergoing medical treatments, experiencing addiction, and/or were just anxious adults.
Biofeedback enhancement: In 1981, researcher Arturo Manns discovered that 15 minutes of stimulation with isochronic tones enhanced biofeedback protocols for bruxism (grinding of teeth). They did this by increasing muscle relaxation superior than standalone biofeedback. Brainwave entrainment is different from biofeedback in that it does not allow the person to consciously control their brainwave state.
Absolutely. Binaural beats were first discovered over 150 years ago, and their use in brainwave entrainment audio has been the subject of a great deal of scientific exploration over the last 35 years in particular. Millions of people use brainwave entrainment music to enhance their quality of life and to experience deep relaxation. In fact, brainwave entrainment technology is now used for more than just meditation. It is also used by a variety of practitioners and private users for improving self-confidence, stress relief, pain management, relaxation, improving and concentration and improving the quality of one's sleep. If you would like to read an objective third party report on binaural beats, please refer to this Wikipedia article.
Because of the way they are created, there may be a positive benefit from listening to binaural beats without considering the brainwave entrainment aspect, but I haven’t seen any research on that. I first discovered brainwave entrainment through binaural beats about 10 years ago now, but they didn’t do anything for me. So I’ve never been a regular user of them. I believe isochronic tones are a more effective way to produce hemispheric synchronisation because they produce a much stronger response in the brain

Practitioners are discovering a number of different areas in which entrainment therapy may bring positive benefits. From managing mental health more effectively through to providing increased mental focus and concentration, it is thought the technique can be adapted according to the specific issues being treated. An improved immune system, enhanced levels of pain management, and a reduction in autoimmune disorders are also thought to be achieved through the therapy, leading many individuals with chronic ill health to consider brainwave entrainment as a non-invasive yet effective therapy.
