So often it is presented as such a highly scientific technology that can only be created by “experts”. Buzz words like “scientific”, “certified engineer”, “frequencies”, “cortical evoked response”, “anterior brain activity”, are used to make it seem over-complicated, and pseudo-scientific pictures of “data” and “brain readings” are pasted all over sites to further qualify claims of how powerful and amazing these people’s product is.
A crossover RCT of a single session of theta stimulation in four healthy adults reported no significant improvement in verbal fluency or attention associated with the intervention and a reduction in immediate recall. Controlled comparisons reported significant benefit from the intervention in all three outcomes measured. Six pre/post studies reported significant benefit from the intervention for 19 of 28 cognitive outcomes.

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.
In general, we are accustomed to being in the beta brain rhythm. We are in a Beta brainwave pattern when we are consciously alert. It is the default and dominant brainwave for most of us most of the time. We are in Beta when we feel agitated, tense, hurried, pressured, afraid and stressed. The frequencies range from 13 to 60 pulses per second in the Hertz scale.
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.

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!)
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.
Over the past few years, brainwave entrainment products have made a great rise in popularity, reaching more people than ever before and peaking their interest with the many benefits ensured. We now have a continually expanding pool of options to choose from, as well as more information and scientific research on the subject than in the past.  Brainwave Entrainment audios, and the products being made with this technology are literally changing the game in the personal development field, and have become one of the largest catalysts in our recent evolution as a human race.  In fact, these audios may be one of the main contributing factors in unlocking the potential to tap into the untouched 98% of our brains that we are currently not using.

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.
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
Audio-Visual Entrainment (AVE) is a technique that utilizes pulses of light and sound at specific frequencies to gently and safely guide the brain into various brain wave patterns. By altering your brain wave frequencies, you have the ability to boost your mood, improve sleep patterns, sharpen your mind and increase your level of relaxation, all with the simple push of a button!
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.
Alpha stimulation: Stimulation of alpha waves has been shown to provide stress-relief among employees, is able to provide pain relief, and improve measures of competence and recognition. If you have significant work-related stress, entraining certain alpha frequencies may help you decrease arousal and improve relaxation. Post-surgical stress doesn’t appear to benefit from alpha stimulation.
NeuralSync™ is the ONLY technology that utilizes FOUR SEPARATE yet synergistically-interactive frequencies precisely calculated to induce each mental state offered in our catalog. Our exclusive 4-W.T.S.P.™ technology creates waves in a balanced 4-dimensional pyramid that are collectively complementary and interactive. Unlike other related programs that use only a single binaural beat or isochronic tone frequency (or several in sequence), NeuralSync™ applies all four simultaneously to immerse your brain into targeted and harmonizing perspectives.
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.
A common element in recordings incorporating alpha and theta frequencies is a steady but barely perceptible rhythm of the frequencies themselves. This subtle and calming pulse mixes with sounds of gentle breezes, distant bird songs, and the slow progression of deep synth notes. Underneath this, below the audible sounds at sub 16 hertz levels, other frequencies intermingle, deepening the merging of conscious and unconscious mind.
Theta brainwaves in the frequency range of 6 to 9 hertz are known as thalpha waves because of their proximity to alpha waves. They are seen during states of high suggestibility, during hypnosis, and during paranormal experience and are also connected to an increase in human growth hormone (HGH) levels and higher blood flow to the brain. Theta brainwaves sit between the realms of the subconscious and conscious mind, making them an especially useful brainwave state for developing creative thinking, working through emotional problems, and integrating subconscious and conscious experience. 

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.


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.
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.
If brainwave entrainment leaves you with unwanted side-effects (see below) or discomfort, you’re probably encouraging a range of brainwaves that are already excessive in some area of your brain. The way around this is to get a brain map to see what your brain’s strengths and weaknesses are, and see what (if any) brainwaves could use some encouragement.
