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.
Our everyday, waking brain used for active intelligence operates at approximately 13 hertz, which is in the range of high alpha or low beta frequencies. People who have certain learning disabilities and problems with attention often have low levels of 13 hertz frequency brainwaves in crucial areas of the brain used for sequencing tasks and doing simple math calculations. This is one concrete example of how brainwaves are associated with thinking and behavior. Each identified brainwave frequency has a different effect on a person’s ability to think, act, and feel.
Monaural beats have similarities to binaural beats, but the two separate frequencies are delivered through a pulse pattern and mixed before they reach the listeners ears, resulting in the advantage of being audible without stereo headphones. However, using stereo headphones intensifies the effectiveness of monaural beats and is recommended for the best effect. 
Hi Rona, thanks for your compliments on my videos and the music I use, I’m pleased you’ve found them helpful. Regarding the pulse-like sound you’ve been hearing, I’ve never had anyone report something similar to that before. I also haven’t heard anyone on brainwave entrainment forums mention it. That is very unusual and because I’ve never come across it before, I’m afraid I don’t know what would cause that.
Additionally, most of the studies have been conducted with extremely small samples and the touted benefits are vague. When studying the effects, it would be beneficial to hook each participant up to an EEG, note initial brainwave activity, then post-entrainment, note any changes. Although certain conditions share similarities in brainwave activity, this is clearly not always the case.
My voice is relaxing and relaxation is pleasurable. These mental directives soothingly lull your conscious mind into ending its internal dialogue. It is the conscious mind that does ALL of the worrying, nagging, second-guessing and basically all of the incessant mental chatter and constant inner dialogue that can keep us trapped by our own view of reality, whether these views are good for us or not.
Brain Wave Entrainment is any procedure that causes one's brainwave frequencies to synchronize with a periodic stimulus (sound, vibration or light) having a frequency corresponding to the intended brain-state (for example, to induce a trance, dreams, sleep or relaxation.) It is also called the Flicker-response because of how staring at a campfire or the flickering of a burning candle can lull you into a state of calmness and serenity. There was an extensive article on this phenomenon by Gerard Oster in Scientific American in 1973. It may sound novel, but in many ways, this is old tech.
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.
“A light sound machine is a brainwave entrainment tool.  Using sound (headphones) & light (strobe light goggles) stimulation, listeners are gently guided into specific brainwave states. Each audio beat and pulse is a specific frequency. Our minds ‘think’ in terms of frequency. Brainwaves change frequencies based on neural activity within the brain. Hearing and vision are considered the favorable senses for affecting brainwaves safely. By presenting beats and pulses to the brain, the brain begins to mimic or follow the same frequencies. This process is referred to as entrainment. In essence, these instruments speak to the mind in it’s own language – the language of frequency.”
Then in my own research regarding my life-long hypertension and its resistance to medication, I became very concerned when I learned that 145/95 is the gateway to dementia. At that time my BP was consistently 145/95. Then, even worse, it started to become routinely 161/106. I was simply unwilling to take more medication with all its attendant side effects, so I started researching natural solutions. I became aware of a breathing apparatus which sold for $300 that would help me train myself to deep breathe, thereby reducing my blood pressure. $300 seemed like a lot, but not in the scheme of saving my life. I started thinking. I already knew how to breathe from my brief studies in Chi Gung. I simply needed something to help me focus my mind. I tried using the Chi Gung breathing while simply counting 200 breaths. It worked for a short while, but I quickly became far too bored, even though I knew it could be a lifesaving measure. I had been considering EquiSync for sometime, and realized it was much less expensive than a $300 breathing regulator, and that it might serve a dual purpose. So I purchased the entire suite.

Until NeuralSync™, brainwave entrainment involved inferior linear, single or sequential protocols - such as binaural beats or isochronic tones - that were natively restricted in their ability to affect the natural complex dynamics of the brain. But now, NeuralSync™ significantly improves entrainment by incorporating EIGHT SEPARATE BUT SYNERGISTICALLY-INTERACTIVE DIMENSIONS into a dynamic and cohesive process powerful enough to compel the brain to produce whole-brain synchronization for intense effect. Incredibly superior to binaural beats or isochronic tones, NeuralSync offers an entrainment experience beyond anything you've used before.
Placebos do not work on me. Heck, even some low-mid doses of proven, effective medicine do not work. Or work well. Ever since I fell terribly ill in grade school, my brain had fundamentally changed. Before, I could comprehend anything. Tell me, show me and I understood it – no matter how advanced it was. I was in the top 98th percentile in the nation. BUT, you never know what you have until it is gone!

The reason I am telling you this is to consider that it is critical for you to seek advice from sources that have wide-spreading experience with brainwave entrainment. Having personally used the technology for over 13 years, in combination with many other more ‘traditional’ methods such as yoga, meditation, visualizations, positive affirmations, NLP, etc., I believe that my personal experiences and the in-depth research I have conducted in order to make sure I approach this safely, can serve as a good starting point for you.

I have received many requests for live sessions and personal support via telephone and video chat (Skype or Facetime). I am proud to announce that you can now schedule your own appointments with me for personal consultations, hypnosis sessions or any general counseling, questions or concerns about your specific needs, life coaching, self-help issues, dream guidance, spiritual matters or just random questions about consciousness or reality in general. I look forward to speaking with you on the phone or video chatting via Skype or Facetime.
The brain produces electrical signals. These signals change depending on what we are doing and what mental state we are in. For instance when we sleep these signals are different from when we are awake. This brain activity can be measured with EEG. It will output in Hz (Hertz - cycles per second) these electrical signals. The most dominant brainwaves will tell us what sort of state a person is in. The slower vibration (lower Hz), the more relaxed that individual is. Using audio technology we get the brain to start following the beats or pulses in a sound if done exactly right.

An important objective of entrainment is to produce a dissociative state, which is a meditation-like state of deep relaxation. It is the brain/body rehabilitative benefits produced by this deep trance-like state that makes AVE so useful for so many conditions. The dissociative state can be first observed by noticing deep and diaphragmatic breathing. Hands and feet become warmer as arteries dilate. Skin color will become pinker as blood flow increases throughout the face and body. Blood flow will increase in the brain as well. The person will experience feelings of profound relaxation and contentment as beneficial neurotransmitters are released into the brain. When in this deep state, the brain/body’s regenerative repair chemicals (parasympathetic hormones) and stabilizing neurotransmitters such as serotonin, endorphins and dopamine are released, which restore good brain function. AVE contributes to this restoration by providing a stress-break, increasing cerebral blood flow and encouraging impaired neuronal firing which allows the brain to return to normal function.

Stress: In one randomized controlled trial with 108 participants, a single session of alpha and delta stimulation resulted in significantly less anxiety in surgical patients. Another session of theta stimulation resulted in improvement in certain measures of stress. Stimulation with certain frequencies of alpha and beta were reported to provide the most significant benefit for those who are stressed.


The use of brainwave entrainment techniques offers many benefits for overall health and well-being, including improved emotional stability, increased cognitive function, and a deepening of creative insight. Much of this benefit derives from the hemispheric synchronization occurring as a result of entrained brainwaves. This effect happens when the electrical impulses in both hemispheres synchronized to the same frequency being delivered through the entrainment source.
I like it. I like the fact that I can just sit there and observe my thoughts and feelings and then go back to watching my breathing. It really does teach me to be centered and balanced. I look forward to the next several weeks. By the way, what I am doing now is meditating for 23 minutes in the early morning and again 23 minutes in the early evening. I’ll check back with you.
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.
Regarding split hemisphere isochronic tones. Think of this as two separate isochronic tones tracks playing independently of each other, one playing in one ear and the other one in the opposite ear. Better still, imagine someone playing and recording a drum beat at a rate of 5 taps per second (5Hz – 5 cycles per second). Then a separate recording of a drum beat is made at a rate of 10 taps per second (10 Hz). You then make an audio track where the left ear/channel hears the 5 drum beats recording and the right ear/channel hears the 10 beat recording. With headphones on, each ear can only hear each respective drum beat and not the other. So you are hearing two different beat recordings at the same time, but it’s different in each ear. A split hemisphere isochronic tones track works just the same. You hear two beats at the same time, not two tones as with binaural beats that create a single beat, but two different speeds of beats in each ear. This is what enables you to stimulate and influence each side of the brain with a different frequency of beat. Binaural beats can only stimulate and influence a whole brain effect using a single beat.
Good to hear from you and glad you got some value from the article. In total honesty I do feel that brainwave entrainment is safe, and that the big point is not to over-use it, or to push yourself too hard. You can almost think of it like an herb or nutritional supplement. You don’t expect big results the day/week of taking it, and if you don’t get results, you don’t keep taking more. You take it in regular safe doses over a recommended period of time and let it synergistically work its magic. Generally I think you are safe to listen to the audio you made, I just recommend taking it gradually with gamma in particular. Listen for just 10-15 minutes at first and see how your brain handles it. If it doesn’t produce any unwanted feelings then jump right in. But even then I recommend only listening once per day, and taking one day off per week.
The only downside is that there is a limited choice available – only 8 tracks in fact (but they are so powerful you are likely to forgive them). The tracks range from the performance enhancing Deep Concentration, the amazing Crystal Clear Mind (which I count as one of my secret weapons when I want to get something done quickly to meet a deadline). And the awesomely mind expanding God Consciousness.

The technology transmits voice messages on close to ultrasonic frequencies that we can not consciously hear, directly into the subconscious mind, with no chance for the conscious mind to filter the information, making it powerful enough for subliminal control. This technology is now available for self improvement purposes with categories such as:  Self confidence, motivation, focus, stress relief, sleep and memory improvement. You can also get your very own custom subliminals to program yourself with anything you want. In 1996, Edward Tilton, President of Silent Sounds claimed that such technology had been used successfully even in military operations to make enemy troops lose morale and surrender. Now we use it for self improvement!
This is the reason why I stress that one should ALWAYS read the instructions provided by the brainwave entrainment product creator, and always do their due diligence in researching the source of any products they purchase. When using a high quality product, these instructions are clear, precise, and always backed up by an extensive network of support and additional information. The product creators who have put in the necessary amount of effort and time to come up with a high quality product always make sure that you don’t get it wrong. 
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.
You’ll learn about the science behind Holosync®, how it works, what happened as over 2.2 million others used it, and much more. This book means so much to Holosync® users that many bring it to public events so I can autograph it for them. Embarrassing for me, but also a compliment—and evidence of how much Thresholds of the Mind means to those who’ve read it.
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.
Participants in the included studies were children and adults, either healthy or with conditions such as learning disabilities, attention deficit hyperactivity disorder, migraine, stress, anxiety and myofascial pain. Interventions included single, alternating, ascending or descending frequencies of photic or auditory stimulation or audiovisual entrainment selected either by the participant or by the investigator. Nearly half the studies used single sessions and the rest used multiple sessions ranging from nine to 100. Length of session varied from 0.5 seconds to 60 minutes. Frequency of session varied from twice daily to weekly. Outcomes reported in the review included cognition (including verbal skills, performance skills, attention, memory and overall intelligence/achievement), short- and long-term stress, pain, headache/migraine, mood, behavioural problems and premenstrual syndrome (PMS).
