One of the more fascinating aspects of what brainwave entrainment does, long-term, is the growing of your mental threshold, and your self-awareness.  I have been a participant of the Holosync Solution for several years, and its maker, Bill Harris, has gone to great lengths to explain why this technology does this.  Much of his research is based on the concept of Entropy and Open Systems, (an idea that nominated its discoverer for a nobel prize).  The brain being an open system, and the technology being a specific type of entropy, this technology has been shown to help the brain reorganize itself at a “higher level” through the growth of new neural pathways. This basically means that 

Theta waves have another interesting characteristic. The Earth has a measurable resonance of 7.83 hertz known as the Schumann resonance. Because the Schumann resonance is a constant background frequency surrounding all life, it may play a special role in biological activity. The Schumann resonance frequency falls within the range of theta brainwaves and may have something to do with why these brainwave frequencies are so powerful. 
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.
We all experience different states of mind each day: states such as sleep, focus, or creativity, for example. Every state of mind has a unique electrical signature that can be detected in the brain. These signatures are known as “brainwaves.” Using specialized equipment, these waves (or frequencies) can be measured and recorded, allowing us to map what brainwaves are present during certain key states of mind.
Because each track is specifically aimed at attaining a certain outcome, you can pick exactly which track you want for what you want to do. This is great for beginners because you can start off with some simple tracks such as Instant Energy Boost or Endorphin Release. And then if you find you like them you can choose some of their more hardcore stuff (such as Lucid Dreaming or Shaman Consciousness).
Tracks that move from alpha to theta can be a perfect vehicle for transitioning from a hectic day into a relaxing and rejuvenating sleep. Beginning with alpha waves takes you into a light but still alert meditative mind state where the difficulties of the day can be resolved and put to rest. Later, theta waves go deeper into the unconscious, preparing you for sleep and dreams.
Specific tones that resonate at certain frequencies are created and embedded within the acoustic architecture of the original waveform. Your brainwaves latch onto these embedded carrier frequencies and attune themselves to the same vibratory rate. Brainwave entrainment now occurs that is similar to binaural beats yet there is no need for headphones to deliver these entrainment effects.
When making an educated decision on what product is best for you, it is important to have a general understanding of how the technology works, and what the benefits are of visiting the specific brainwave states.  Please click the link to visit a more detailed article –  How Does Brainwave Entrainment  Work, and the benefits of Alpha, Theta, Delta, and Gamma brainwaves.
While binaural beats are the most common technique we use for producing brainwave entrainment music, we do use other brainwave entrainment techniques such as isochronic tones, monaural beats and amplitude modulation. If these techniques have been used then you will find them mentioned in the written description of the music productions that include them. If not mentioned, then you can assume that binaural beats are the only brainwave entrainment technology in use.
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.
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).
No matter what you use: USE it. At least for a couple weeks.  And have realistic expectations...  Brainwave Entrainment is not some pill or quick solution (even if there are some sessions that usually give almost immediate results e.g. for sleep induction or pain relief), it is a tool that requires training and works best in combination with good breathing / meditation techniques.
From the deepest, sincere, compassionate, and loving part of my soul; I offer thank you. : ) By saving me, I believe your organization did a service to society as a whole, for now I am like a ripple in a pond that will reverberate good vibes to all who I come into contact with. I express compassion, understanding, and knowledge to all who I see need your life saving, and healing product. Like a missionary I desire to spread it; for it is pure, good and loving to my fellow man.
You may already have a good feel for where each of the different brainwave states takes you, and know intuitively what will work for you the best on a day-to-day basis with your meditation practice. If you are a little fuzzy about the differences between the brainwave states, however, and would like to have a really clear, visceral sense of what each state does for you and how they resonate with you physically, mentally, and emotionally, one way you can find out is to listen to Harmonic … [Read more...]

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.
I’ve experienced all sorts of internal effects, ranging from feeling “high” to losing all awareness of my body, to seriously feeling like my head was turned completely backwards, only to just have to open my eyes to find it facing straight forward where I left it, to drifting into transcendent states of mind that can hardly even be described with words.

-Frequency of the Tone Itself that Makes the Beat (Carrier Frequency): The first frequency was the rate of the beat pulsing on and off. This frequency is the sound frequency of the actual tone that comprises the beat. This frequency also has an effect on the way the technology affects your brain and consciousness. For example, too low of a carrier frequency for a binaural beat can be too much for a beginner’s brain to handle at first, and too high of a carrier frequency can be not enough for an experienced meditator’s brain to make big changes.

Sleep improvement: There is significant anecdotal evidence that sleep induction and/or quality may be improved as a result of brainwave entrainment. While it is important to consider the placebo effect or simply the effect of a relaxing sound, many people have reported noticeable improvements in their ability to fall asleep and wake up feeling refreshed as a result of entrainment. Entraining frequencies within the slower wave ranges such as alpha, theta, or delta, may help individuals transition more quickly to those states.
Basically, the brain produces a phenomenon that results in low-frequency pulsations in the amplitude (volume) and sound localization of a perceived sound when two tones at slightly different frequencies are presented separately, one to each of a person’s ears, using stereo headphones.  A beating tone will be perceived, as if the two tones mixed naturally, out of the brain. The frequencies of the tones must be below 1,000 hertz for the beating to be noticeable. The difference between the two frequencies must be small (less than or equal to 30 Hz) for the effect to occur; otherwise, the two tones will be heard separately, and no beat will be perceived.
One of the most fascinating and beneficial things about Delta brainwaves is their ability to stimulate the release of anti-aging hormones in the body, such as HGH (human growth hormone). Increased melatonin levels are also common in this state, and regular visits to Delta have also been shown to decrease cortisol levels. (Cortisol is a hormone that is released during stressful situations, that has been linked with the aging process.) In a nutshell, Delta brainwaves are very healthy, and until now have only been accessible to us during deep sleep.

Business executive and radio producer Robert Monroe started experimenting with brainwave entrainment and has a series of powerful out of body experiences using it. In 1971 he published his cult classic “Journeys Out of the Body” sharing his experiences. He later created one of the first audio entrainment companies called Hemi Sync, alongside the Monroe Institute of Applied Sciences.


Hi Amandeep. I am so sorry to hear you are having these troubles. I am not familiar with Marisa Peers materials, so I cannot comment on this, but I can tell you we have never had an experience like this reported from using the audios we offer on this site. I would cease any and all hypnosis or brainwave entrainment audios, and contact your doctor. The issues you are mentioning sound like they could be a physical issue that may be related to more than the audios you’ve listened to.
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.

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.
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.
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.
When I am using equisync I feel kind of like it is “pushing me” – I guess this is the right way to say it- to achieve better results, which I really like. I fall asleep quickly, and sleep all night and even wake up before my alarm goes off. I feel noticeably calm during the workday- which is very helpful for what I do. I really like the warm feeling (my whole body gets really warm during my equisync meditation sessions) and I feel kind of like Im floating while listening. The soothing rainfall is also very nice.

Brain Sync audio programs deliver pure and precisely tuned sound frequencies to the brain to drive brain activity into high level states of mind. These are brain states known as Alpha for heightened creativity and deep relaxation; Beta for high focus and concentration; Theta for meditation, insight and memory; Delta for deep sleep and healing; and Gamma to increase cognition and improve IQ.
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.

In BrainAscend, each brainwave frequency is stimulated for several minutes before progressing deeper.  Much like a staircase type of progression, but with small and smooth steps. This is the most effetive way and also stimulates the release of "feel good" brain chemicals such as serotonin which makes you feel happy. This chart shows the range that each level covers as well as the whole program.

I also suffer with migraine for the last 15 years of my life. So, when I know I am going to have a headache I will start meditating and headache suddenly subsided. What an amazing thing you have created here. This is only three weeks of my experience. How much more what I can do after…………By the way I am 49 years old. I just want to thank you so very much for sharing this amazing tape with me. It is so worth it in all aspect. I wish you all the best. How I wish that our paths will cross one day.
Brainwave entrainment is a colloquialism for such 'neural entrainment', which is a term used to denote the way in which the aggregate frequency of oscillations produced by the synchronous electrical activity in ensembles of cortical neurons can adjust to synchronize with the periodic vibration of an external stimuli, such as a sustained acoustic frequency perceived as pitch, a regularly repeating pattern of intermittent sounds, perceived as rhythm, or of a regularly rhythmically intermittent flashing light.
