The basic idea behind the Laxman light and sound technology is that the gentle pulses of light can lead one to the state of mind associated with that particular frequency range. The various pre-programmed “sessions” found in the Laxman mind machine can be used for different purposes, including meditation, stress reduction, accelerated learning, restful sleep, increased creativity, and goal setting.
Targeted hemispheric changes: Some speculate that specific alterations in brain waves can be made on an individual basis. In other words, you can target one frequency in one hemisphere (via the right ear) and another distinct frequency in the other hemisphere (via the left ear). The left ear affects the right hemisphere and right ear affects the left hemisphere.
Chronic fatigue: Subjective improvements in energy level may be reported by those who increase stimulatory beta and gamma waves. Fast waves tend to be associated with higher levels of arousal. Low arousal is associated with chronic fatigue and may be exacerbated by slow brain waves (e.g. theta and delta). As of now there aren’t any studies that have analyzed various protocols for their effect on a person’s energy or arousal.

Research shows that parts of the brain and eventually large areas of the brain begin to resonate sympathetically with this "phantom" binaural beat. This is known as the Frequency Following Response. Subsequent research determined that a binaural beat frequencies drive brain activity into specific brain states. Thus, effortlessly and naturally, your brain activity slides into rhythm with this binaural beat, becoming organized and coherent. Within minutes, the sound frequencies start to balance the left and right hemispheres of your brain – creating a remarkable state called hemispheric synchronization and driving the electrical activity of your brain into powerful states, normally unattainable. Flashes of creative insight, euphoria and a deep sense of calm is often accompanied by this extraordinary brain state.
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.
This is good to understand because this is another area where people can make huge promises that may or may not be true. Even in this realm, there is a level of practicality that can be followed. Even meditating at the rate of a super-human monk is not going to “magically solve all your problems”. This technology cannot pick negative beliefs out of your head and implant positive ones just by influencing your brainwaves. It cannot just make you a different person.
Today, EEG machines are used for diagnosing epilepsy and sleep disorders, for determining dosages for anesthesia, and measuring the brain activity of people in comas or suffering from brain trauma. EEG machines also continue to play a role in researching and understanding brainwave entrainment and developing new and better methods for delivering the benefits of this form of brainwave modification. 
Transparent Corp's Research Area is arguably the most comprehensive resource for collated brainwave entrainment research.   Update: the main research area on Transparent Corp's website is currently being updated, so it is offline.  However, you can still access their peer-reviewed research paper as a PDF here: “A Comprehensive Review of the Psychological Effects of Brainwave Entrainment“.

Naturally "click" with people – To get to the top, it takes good communication. World leaders get elected for their ability to communicate. Business visionaries have ideas that they make tangible by sharing their dreams with others. Pick up artists attract the opposite sex by noticing, and reacting, to subtle body language and saying the right things at the right time. What if you could easily and automatically just "click" with people, and gain instant rapport with your audience?
Generally, the established brain entrainment technology has been to use various static levels, lowering the carrier frequency of the binaural signals over time. By doing this, you basically increase the resonant power of the carrier frequency to resonate more deeply with the resonant frequency of the brain and the nervous system. This process pushes the nervous system over time. The limitation I find with this system is that it takes a static approach, in the sense that it gives the nervous system the same degree of stimulation day in and day out. The idea here is that if you keep whamming your nervous system with the same stimulation on a daily basis, it will eventually kick in and learn. Then your nervous system and your brain will jump to the next level.

The pitch frequency measures and describes what a beat sounds like, i.e. does the isochronic beat have a deeper bass sound, or is it high pitched and sharper sounding? The beat waveform frequency describes how many times the beat is repeating per second, i.e. how fast it is beating. You don’t really need to concern yourself about the pitch frequency, as that doesn’t have a direct influence on brainwave entrainment and doesn’t play a part on the measurement on an EEG. I only mentioned it because you were referring to humans not being able to hear below 20Hz. I change the pitch frequency just to suit the mood of the track. For tracks that are to be relaxing, for meditation or sleep, I tend to use a lower pitch frequency so it sounds deeper and more relaxing and I never have that lower than 100Hz. For an energizing, high focus track I might use a more higher pitched 200Hz isochronic tone, because that is sharper sounding and less likely to make you feel sleepy. That’s all you really need to know about the pitch frequency.
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
A study by Tina Huang, PhD, and Christine Charyton, published in the September 2008 issue of the journal, Alternative Therapies examined the results of twenty previous studies measuring the effectiveness of brainwave entrainment for improvements in cognitive dysfunction and deficits, stress reduction, pain management, migraine and headache control, pre-menstrual syndrome, and behavioral difficulties, and all showed significant improvement in symptoms using entrainment techniques.
it says the following: “Running a delta sleep session throughout the night is not recommended as it can interrupt the normal sleep cycle”. I’ve been looping pure delta isochronic tones for about 5 days now, and have had quality sleep. Should I continue looping delta or should I let the videos play out without looping them? Will it will harm my health to do loop delta while I sleep?

- Added the ability to create a playlist of your own iTunes library music and use it as the background. The behavior of the app when iTunes music is used instead of the included ambience is slightly different so please review the help. Notably, unlike our included ambience which can be played at a volume below the device volume, iTunes music can only be played at the device volume. So when playing iTunes music the Ambience volume slider disappears.
Thanks for your appreciation of what I’m doing. I’ve been asked for help with autism a number of times over the years, so it’s something that I’ve often looked into and tried to find new information about. Unfortunately, I’ve yet to find any specific research relating to it and using the type of brainwave entrainment tones I use. There are a number of opinions and claims out here, but I’ve often found them to be conflicting. While some are recommending higher frequency gamma waves, others are recommending lower frequency alpha and theta waves while meditating.
The fastest way to make brainwave entrainment technology work for you on your path of spiritual development is to pull back ever so slightly once you realize you have reached the peak of your nervous system’s capacity to recover from the stimulus. Because your nervous system is like a sine wave, when it is about to go into its valley, you pull back just a little bit, thereby giving your nervous system, energetic system, and hormonal system enough room to pull out all of their recovery powers. This allows you to recover from stimulus more quickly, and then you get past the waning stage and back to the waxing stage, where you can start pouring on the juice a little bit more again.

“…humans have always been intrigued by the possibilities for influencing mental functioning that emerge from combining rhythmic sound and rhythmic light stimulation. Ancient rituals for entering trance states often involved both rhythmic sounds in the form of drum beats, clapping, or chanting and flickering lights produced by candles, torches, bonfires, or long lines of human bodies passing before the fire and chopping the light into mesmerizing rhythmic flashes. From Greek plays to Western opera, our most popular entertainment forms have made use of combinations of lights and sounds. Some composers, such as the visionary Scriabin, actually created music intended to be experienced in combination with rhythmic light displays.”
Thanks Lorita. There hasn’t been any isochronic tones research that I’m aware of, for anti-aging, fat loss or attracting people, or any significant anecdotal feedback. You could combine positive affirmations or hypnosis scripts with isochronic tones to try and change habits and that could help with fat loss or build confidence to attract people. But it would be the affirmations and hypnosis doing most of the work, the isochronic tones would just be used to help relax the listener and put them in a more suggestible state. I don’t believe isochronic tones can affect those things, without being used in combination with some kind of vocal mental programming.
I was diagnosed with “acute high anxiety, major clinical depression,and ptsd” 16 years ago. I have clinically addressed these disorders with a number of medications, which none have helped. I am so lucky I have found this simple easy to practice method of practice, that I have found these beats and tones so essential that I indoctrinated them into my daily life, and have come to the realization, that someday very soon I will awake and will not suffer from these burdens these disorders ever again.
There are also ways of directing the entrainment pattern to further stimulate the brain in a desired way. Not all audios stay at the same frequency the whole time. Some will increase and decrease for a desired effect. Some will blend different beats at certain time to exercise the brain in a specific way. It is things like this that separate a good audio from a mediocre audio, and the difference between the two is undeniable when compared.
I personally have been experimenting with binaural beats – both in and out of the float tank – for the past year or so and they have quickly and easily become one of my favourite go-to “hacks” for helping me achieve a desired state of being. From listening to a specific track right before going to sleep which helps put my mind and body in a state of relaxation and recovery to, on the flip-side, listening to a track that helps prime my brain-state for creativity and focus right before I sit down to do some work – like writing this blog! They are also an enjoyable and effective asset to try out and experiment with while in the float tank. For the reasons mentioned above, as well as the sound frequencies can resonate a subtle but noticeable vibration in the tank, water and your body making for quite the unique floating experience!
Good article. Richard, there are numerous studies dictating the research behind entrainment. Please see http://brainwavebooster.com/brainwave-entrainment-research/ for a list of many peer reviewed studies. The author here is totally correct in his labeling of brainwave entrainment as a therapy tool. Hope this helps. There are other studies out there as well, one only needs to Google it.
It is important to take an objective look at published scientific evidence to determine whether brainwave entrainment is an effective treatment for certain conditions and/or symptoms. Most preliminary evidence suggests that while the technology will not cure any condition, it may be a successful adjunct treatment when used carefully with the proper protocol.

Initially the children were entrained to a mu-alpha rhythm (7 to 9 Hz) to decrease theta waves. After the initial mu-rhythm entrainment, they entrained SMR-beta waves for 22 minute sessions. The results as interpreted by TOVA demonstrated significant improvements in: inattentiveness, impulsivity, and variability. Teachers and parents also reported behavioral improvements among the children. Using the right brainwave entrainment protocol may be a potential Adderall alternative for those with attentional deficits.

Binaural beats were the first method discovered for brainwave entrainment and works by delivering tones of different audible frequencies to the two ears with the difference in frequency between the two tones being the frequency of entrainment. The difference in frequency between the two tones must be less than 30 hertz, and this resulting frequency is called a beat or the target frequency, and it is processed in a brain region called the olivary body. When listening to such tones with stereo headphones, the two hemispheres of the brain become synchronized at the target frequency.
I have never been more creative, productive, more loving to all people nor have I ever been happier in my life. All the wisdom I have found in my pursuit of happiness was somewhere in my intellect. Now it is a part of me. I am using it. I now consider myself a model for younger people to let them see how it is possible to function and be everything they’ve wanted to be. I just celebrated my 85th birthday and I am as young as when I was 25. Thank you for giving me the gift of my true self.

Advanced NeuralSync™ technology uses multiple powerful sound frequencies and energetic augmentation that FORCES your brain to STOP producing defective brainwave patterns and OVERRIDES them to create positive neural feedback instead. As you continue use, your brain re-learns to produce healthy, beneficial and healing brainwaves on its own!
I enjoy this one called: Cognition Enhancer For Clearer and Faster Thinking – Isochronic Tones (Electronic) … I seem to enjoy it. Any harm in just listening to this one every day for 30 minutes as a routine daily thing, just like brushing your teeth and making your bed. I would just use it at times when I’m working at my desk, maybe even reading the online news etc…Thoughts?

Most wisdom traditions have employed methods that allow the subjects' brain waves to slow down such as meditation, [Hindu] kirtan, [Gregorian, Menzuma or Sufi] chanting, Hebrew davening, Native American drum circles and rain chants, Tibetan prayer bowls, and whirling dervishes and African trance dancing. The rhythm of these wisdom tradition technologies actually slows people's brain waves from their normal busy brain frequency we call Beta (13-30 cycles per second or Hz), to Alpha (8-13Hz) -- meditation, Theta (4-8Hz) -- deep relaxation and dreaming, and Delta (.5-4Hz) -- slow wave or dreamless sleep.

Unlike many traditional therapies for dealing with stress, anxiety, depression or cognitive impairment, entrainment does not require a focused effort from the person having the therapy, as the brain instinctively follows the frequency. This makes it a much more effective therapy for managing some of these challenging conditions, by automatically inducing a sense of relaxation and a reduction in negative physical and emotional patterns.

Another small scale study with 30 children were entrained with a starting frequency of 14 Hz and ramped up to 40 Hz. Following the excitatory-based protocol, they were then given a protocol that started at 40 Hz and decreased to 14 Hz over 6 weeks. The results indicated that the children significantly improved in arithmetic abilities based on the WISC-III.
I’ll give you another relevant analogy.  When you are bodybuilding, working hard to build strength and build your muscles, you can push yourself to the point that we know is healthy.  But what happens if you try to max out with the same exercise past the point that we know your body can handle?  You’re going to get hurt, and you’re not going to get buff any faster.  You can’t just push yourself to the limit with the barbell as many times as you want in a day/week.
Really great stuff here, man. Well done! Without taking anything away from the article it would have been great to have under one “roof” similar information about hypnotherapy and subliminals. I invested quite a lot in buying binaural cd’s but after reading your material I think that for short term effects isochronic tones rather than binaurals are the technology to go for now. For longer lasting and possibly permanent effects I’m not sure whether I should go for hypnosis or subliminals (or both). An article as well written and comprehensive as yours but focusing on hypnosis vs subliminals would have completed the circle for me. The stuff I’ve read so far on binaurals vs isochronics hasn’t really done it for me. Any chance you could give it a shot?
