Delta brainwaves have the slowest frequencies, ranging between 0.1 and 4 hertz, and these are the brainwave states associated with deep sleep, trance states, and unconsciousness. Few people can remain awake during delta brainwaves states, although this state is recorded in awake infants between ages of three months and one year and also in babies just before birth. Delta waves are also linked with increased production of HGH, DHEA, and the neuro-transmitter serotonin.

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.

I was not looking forward to returning back to my house as I live on my own so was very pleased to see that the “equisync” CDs had arrived in my absence. Ever since I have been back I put a CD on each evening and the change has been totally fantastic. The meditation is unbelievably calming and soothing, the inner-voice has been silenced and quite often I just put it on to drop off to sleep with the sound of gently falling rain. I can feel each day starting calmly and things like organising the memorial service have not been the strain and upset I would normally have expected. I could wax lyrical for hours because the benefits are truly and utterly fantastic. Never did I think I would find anything that would lift my spirits, clear my mind, calm the inner space but Equi-Sync has done that, and more.
The training process allows you to consciously access deeper levels of your brain and consciousness. Your whole brain power and function expands. You become intuitive, relaxed yet focused, creative, your thoughts become clearer and information processing improves more and more. The left and right brain hemisphere synchronizes and you'll start using the full power of your left (analitycal - logical - Intelligence) and right (creativity - imagination - visualisation) hemispheres together. To say that this helps in all imaginable areas of your life is an understatement. You'll also begin to discover deeper realities beyond the physical. You become happier, more relaxed and balanced.
5) Your cerebral blood flow is being increased - CBF is associated with many forms of mental disorders, including anxiety, depression, attentional problems, behavior disorders and impaired cognitive function. CBF tends to lower as we age often causing cognitive decline. People experiencing depressed mood usually have lower levels of CBF in the left frontal and prefrontal lobes.
Theta stimulation: There appears to be no benefit associated with using theta stimulation for cognitive functioning, mood, or stress relief. While theta may be a useful way to induce sleep or alter your state of consciousness, there really isn’t much science supporting entrainment in this particular range for most purposes. Photic stimulation of theta between 5 Hz and 7 Hz can be useful for headaches.
There isn’t really a one-size-fits-all track or frequency range which is right for all kids while doing homework. So that does make it difficult to recommend one thing in particular, and why I have a number of tracks for studying and focus. If they have already learnt and understood the information, but are just trying to commit it to memory for a test, then I would recommend an alpha track, like the Memorization Study Aid product I have with the 10.4Hz frequency you referred to. If they are still trying to fully understand what is being taught in a workbook, then I would recommend a track that is mainly beta frequencies, like my Study Focus tracks. In the middle, I have a number of tracks which use a combination of beta and alpha wave frequencies, like Study Booster, Study Enhancer and Cognition Enhancer. The last 3 use similar frequencies but deliver the tones and brainwave entrainment effects in different ways. As we are all wired a little differently it does sometimes take a bit of trial and error, to see what method or frequency range works best for the individual. These types of tracks are made for a general audience. In an ideal world, you would hook up to an EEG and see in real time exactly what a person responds to best, depending on the goal and current state of mind.
·         THETA waves exist between 4 and 7 Hz. This is commonly referred to as the dream or “twilight” state. Theta is associated with learning, memory, REM sleep and dreaming. Memory development is enhanced while in this state. When in a theta brainwave state, memory is improved (especially long term memory), and access to unconscious material, reveries, free association, insights and creative ideas is increased.
Hi Jason, thanks for all the uploads to youtube. I’ve been using them in work recently to help me concentrate and relax. I like the music tracks that you’ve chosen to overlay the tones. A couple of times in the last 2 weeks I’ve experienced the wavy pulse like sound, similar to the tones in my left ear. I wasn’t listening to tracks at the time or that day. It doesn’t last but it feels a bit strange. I wondered if I might have been listening to the tracks too loudly and that it was almost like a type of tinnitus. I’m curious to know if anyone has been in touch with you in the past to say they’ve had a similar experience?
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.
Kelly Howell brings 30 year's experience to her expertise. She has been cited by the Mayo Clinic as "renown for her pioneering work in healing and mind expansion (and) visionary recording techniques." She has collaborated with neuroscientists and biofeedback therapists to invent a sophisticated sound recording technique that makes Brain Sync programs more effective. The result is the most elegant and effective brainwave synchronization audio programs available in the world today. You'll feel the effects from the very first time you listen. With regular use, you'll establish new healthy patterns that last. Brain Sync programs use window frequencies – extremely precise frequencies that fit through narrow biological windows to impact the body at the cellular level. The choice of frequencies selected for each program is based on biofeedback research. Programs are designed to help you self-generate optimized brain states exhibited by remarkable men and women.
However, yoga and meditation take time to learn and master, and until the student becomes proficient, progress can be slow and frustrating, leading many people to abandon the effort before they see the benefits. Brainwave entrainment has the potential for helping a person enter the relaxing and rejuvenating mind-states brought about by yoga and meditation without the learning curve and time needed for mastering these other techniques. Brainwave entrainment may even facilitate learning other mindfulness methods by helping a person achieve success faster and more reliably. 
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.
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.
Ultimately the only way to know if this is right for you, or if it works for you is to test it. A good audio creator should be willing to let you give their audios a test drive to see if it’s right for you. When you test this type of technology, one that is largely left to subjective experience, I would highly recommend you listen to the same audio daily for a full week or two, taking one day off per week. There are many different experiences that can be had with this type of technology, including not noticing it doing anything at all. Having at least 5-10 experiences with it will give you a reliable way to gage whether or not this is going to work for you.
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.
1. Compressed formats like MP3 do not retain the sound quality necessary for the brain to fully achieve brainwave synchronization – and are too inferior to effectively deliver even binaural beats downloads or isochronic tones properly, much less something as powerful as NeuralSync™. Our lossless audio entrains at the precise level guaranteed to induce the most potent response.

To get a full answer you should really get in touch with the owner of the app, because it does really depend on how their track is constructed and how they intend it to work. I have one 50-minute sleep track which takes you down into delta (http://www.mindamend.com/shop/sleeping-and-dreaming/sleep-induction-isochronic-tones/) and that is designed to just get you to sleep, so you just let play until the end. If you played that track on repeat it might make you jump and wake you up, as the track begins at a higher frequency. I have another 8-hour sleep track which is meant to be played all throughout the night (http://www.mindamend.com/shop/sleeping-and-dreaming/deep-sleep-8-hour-sleep-cycle/). So it does depend on the individual track you are using.

Personally I use them whenever I feel like it which is often and experience truly amazing and almost immediate life-changing, and surprisingly great results. You can, and I am, literally the most confident, happy, sociable, smooth, funny,smart or intuitive person ever using these recordings. They also have the power to make you tonnes more money by giving you truly amazing wealth psychology. I use them successfully in helping me to make a tonne of money trading stock and other activities.

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. 
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.
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.
Two people with ADHD for example could have completely different ADHD subtypes. One could have inattentiveness as the primary symptom as a result of high theta waves, and the other could have high beta-2 waves as feel hyperactive. While generalized entrainment protocols should be studied, it is important to consider that each person may respond differently to the protocols; each person has a unique neural footprint.
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.
When the brain is stimulated with pulsed sounds (neuro-electrical activity via the nerves originating from the ears), the overall activity of the brain will respond to and align with these pulses. By selecting the desired rate, the brain — via the frequency following response (entrainment) — can be naturally induced towards the selected brainwave state.
The various mental states of the individual are thought to take place across a varied range of frequencies, or brainwaves. By encouraging the frequency following process, entrainment is able to create positive change in the brain, through matching carefully-selected frequencies of light and/or sound. The stimulus enables the individual to access a different state of consciousness, which can be useful for a number of benefits including relaxation, anxiety management, stress reduction and more.
With almost 100 years of research validating the effectiveness of brainwave entrainment, it’s no wonder why it’s used by thousands of people all over the world. What does the future entail in this exciting field? With the adoption of smartphones, virtual and augmented reality, and advancements in technology reducing the cost of EEG and other forms of biofeedback devices, the entrainment possibilities are endless.
Subsequently, the term 'entrainment' has been used to describe a shared tendency of many physical and biological systems to synchronize their periodicity and rhythm through interaction. This tendency has been identified as specifically pertinent to the study of sound and music generally, and acoustic rhythms specifically. The most ubiquitous and familiar examples of neuromotor entrainment to acoustic stimuli is observable in spontaneous foot or finger tapping to the rhythmic beat of a song.
