Hemi Sync Binaural Beats raise questions - here are the answersQ: In a nutshell, what is Hemi-Sync?

A: Hemi-Sync is a scientifically based and clinically proven “audio-guidance” technology that uses sound to influence brain-wave activity. This patented, and highly sophisticated technology is backed by over 40 years of research. For more details, see the expanded explanation inWhat is Hemi-Sync?

Q: How does Hemi-Sync work?

A: Hemi-Sync is an audio-guidance process that works through the generation of complex, multi-layered audio signals, which act together to create a resonance that is reflected in unique brain-wave forms characteristic of specific states of consciousness. The result is a focused, whole-brain state known as hemispheric synchronization, or “Hemi-Sync,” where the left and right hemispheres are working together in a state of coherence. As an analogy, lasers produce focused, coherent light. Hemi-Sync® produces a focused, coherent mind, which is an optimal condition for improving human performance.

Q: Are the Hemi-Sync frequencies the same on each title ?

A: No. The Hemi-Sync process has evolved into a sophisticated multi-layering of Hemi-Sync signals – “designer mixes” of sound frequencies, fashioned to be optimally effective for a given application. Naturally, Hemi-Sync sleep products incorporate predominately delta frequencies; learning products predominately beta and so forth. However these designer mixes are supplemented with special sound frequencies, which enable the desired result. This is the “key” to the effectiveness of Hemi-Sync.

Q: Can someone with hearing loss benefit from Hemi-Sync?

A: Yes. Doctors and individuals with impaired hearing tell us that the frequencies are effectively carried to the brain by the bones in the ear canal.

Q: Is Hemi-Sync like hypnosis?

A:Yes, they are similar. Hypnosis is an induced, altered state of mind, in which the body is deeply relaxed, sufficient to be temporarily ignored, except for demands like bladder fullness, etc. It is sometimes described as “focused concentration.” This “state” is one in which the participant has perhaps even more control over the body and self than in “ordinary” states of consciousness. Witness the fact that hypnosis is sometimes used for pain control in minor surgeries, childbirth, and even dentistry. It is an expanded state of awareness, in which one can be fully aware of the sensory data from the environment, (sound, light, temperature, etc.) and at the same time can develop awareness of other data sources as well, such as past lives, out-of-body information, information from guides, one’s inner self, etc. Neither state can “make” you DO anything. You are able to maintain your faculties for choice and value systems, including choosing to follow suggestions from the therapist or not. Hemi-Sync is designed to leave control in the hands of the listener as well. In this sense, it’s somewhat related to self-hypnosis. Hemi-Sync does not “make” you do anything. It simply creates an effect that helps you move into a certain state, providing that you relax and are open to responding to the Hemi-Sync process.

Q: Are Hemi-Sync products subliminal?

A: No. Subliminal recordings have the intention of embedding a particular thought in the mind of the listener by recording words at sub audible levels, often at high speeds. Hemi-Sync sound patterns, although recorded at a sub audible level, are not verbal messages and are not recorded at high speed. The purpose of Hemi-Sync sound patterns is to assist you in obtaining the focused brain state you desire.

Q: Some Hemi-Sync products have sections in which the voice is too low for me to understand. Isn’t that subliminal? Or is it a defect in the product?

A: No to both questions. By the time the voice becomes low in volume, you are in an extremely relaxed state or perhaps asleep. The words you may not understand are simply a repetition of earlier sections of the recording. They are repeated for purposes of reinforcement, at a very low volume so as not to interfere with your state of relaxation.

Q: Is Hemi-Sync recommended for children?

A: All nonverbal recordings are fine for children. With verbally guided titles, we recommend you listen first and then decide based on your child’s level of maturity.

Q: How does Hemi-Sync® Compare To Other Products?

A: We occasionally receive inquiries from individuals desiring to know how Hemi-Sync compares to other brain-wave products they may have heard about. It would be inappropriate for us to comment on specific products or technologies but following are some observations we can make with regard to Hemi-Sync:

Robert Monroe’s pioneering work with hemispheric synchronization (Hemi-Sync) sound patterns inspired an entire industry of mind/brain products and technologies.

  • Hemi-Sync is a technologically sophisticated process that has been awarded three U.S.patents.
  • With millions of products sold worldwide, Hemi-Sync has been shown to be a highly effective, safe, time-proven technology.
  • Improving the efficacy of Hemi-Sync has been a continually evolving process—which we have remained committed. Today’s Hemi-Sync has been refined with over 40 years of research and development and is supported by numerous studies, reports, articles and testimonials available at www.Hemi-Sync.com. Hemi-Sync has been scientifically and clinically proven to be effective.
  • Over the years, the Hemi-Sync process has evolved into a sophisticated multi-layering of Hemi-Sync signals—”designer mixes” of sound frequencies, fashioned to be optimally effective for a given application. Naturally, Hemi-Sync sleep products incorporate predominately delta frequencies; learning products predominately beta and so forth. However, these designer mixes are supplemented with special sound frequencies which enable the desired result. This is the “key” to the effectiveness of Hemi-Sync.
  • Ongoing Hemi-Sync research has resulted in the development of scores of individual products for specific applications such as focused attention, stress reduction, meditation, sleep enhancement, and pain control, to name a few. Other Hemi-Sync products are available as a series (some of which are progressive in nature) such as the Gateway Experience In-Home training program for exploring states of consciousness.
  • We do not recommend using Hemi-Sync in combination with other devices or technologies that influence brain activity.


Q: What kind of equipment is required to listen to Hemi-Sync?

A: A moderately priced stereo player will work fine. Top-of-the-line equipment is not required for Hemi-Sync to work. Headphones are recommended for best results and a good set of headphones will contribute to your enjoyment. Headphones that enclose the ear are preferred to reduce ambient room noise and provide a more distraction-free experience.

Q: Will conventional speakers work as well as headphones?

A: You can use either. The greater the separation between the sounds introduced into each ear, the stronger the Hemi-Sync effect. We generally recommend using earphones for experiential exercises, because earphones maximize the sound separation and tend to block out exterior noise. Speakers are also fine, and in fact may be preferable when you are playing Metamusic or other nonverbal titles as background while engaged in another activity. Be in the same room as the speakers. To enhance the separation between the sounds, it is recommended to position yourself between the speakers, when possible.

Q: How can I use earphones if I’m only comfortable lying on my stomach or side? And, what about getting tangled in the wires?

A: You may wish to try “ear buds”, which are designed to fit comfortably inside the ear. Earbuds are available at many stores that sell stereo equipment. Alternatively, use conventional speakers, placed on either side of your bed or try a stereo sleep pillow.

Cautions and Disclaimer

While many of our audio products contribute to wellness, they are not intended to replace medical diagnosis and treatment. DO NOT listen to Hemi-Sync® while driving or operating heavy equipment, or with other devices that may influence brain-wave activity. If you have a tendency towards seizures, auditory disorders, or other adverse mental condition(s) DO NOT listen to Hemi-Sync without first consulting your physician. In the unlikely event that you experience any unusual physical or mental discomfort, immediately discontinue use. ALL WARRANTIES WHETHER EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE DISCLAIMED.

Q: Why am I not supposed to listen to Hemi-Sync in my car?

A: When driving, you should pay attention to the road. It’s not advisable to move into other states of consciousness.

Q: Why am I not supposed to listen to Hemi-Sync if I have a tendency towards seizures?

A: Seizures result from abnormal brainwave activity. Hemi-Sync’s influence on brainwave activity might not be beneficial for someone with that tendency.

Q: Is there a problem in making copies of Hemi-Sync products for friends?

A:Yes. Hemi-Sync products are copyrighted. You would be breaking federal laws and therefore be liable to prosecution.

The Listening Experience

Q: What product will enable me to have an out-of-body experience?

A: An OBE cannot be guaranteed. Your ability to experience an OBE depends on many factors unique to every individual, like personal beliefs, possible fear barriers, etc. If you are interested in an OBE, we recommend Hemi-Sync Support for Journeys Out of the Body or the Gateway Experience series.

Q: What if I fall asleep while listening?

A: That’s fine. The benefits of Hemi-Sync are achieved with or without your conscious awareness. Many Hemi-Sync exercises help you achieve a hypnogogic state, that borderline state between deep relaxation and sleep so it’s possible you may drift into sleep. If you want to familiarize yourself with the verbal content of an exercise, listen once, without headphones, while seated in a chair.

Q: I hear a hissing noise on some of the products. Is that a defect ?

A: No, what you are hearing is “pink sound” (sometimes described as a swishing sound). It is a combination of all the frequencies the human ear can perceive, with higher and lower frequencies adjusted to be equal in volume. Pink sound enhances the perception of the Hemi-Sync sound patterns, and therefore plays a valuable role on certain Hemi-Sync products. Dolby® nosie reduction attempts to filter out the pink sound. Therefore, it is important not to use Dolby®, or other noise reduction systems, when listening to Hemi-Sync audio products on tape.
Q: Am I supposed to “see” things when I listen to Hemi-Sync?

A: “Supposed to” really doesn’t apply. There are many ways of perceiving; visualizing is only one of them. Many people experience a physical response to Hemi-Sync and become aware of different body sensations; other people have sensations of hearing or tasting, or simply “knowing.” Enjoy your experience, whatever it is.

Q: How do I know if I’m getting the intended effect?

A: Everyone is unique. Your Hemi-Sync experience may differ from the experience of others. In fact, your experience may be different each time you listen to a particular exercise. Just relax and trust that your experience is right for you at the time.

Q: Is Hemi-Sync beneficial for experienced meditators?

A: Yes. Many long-term meditators report that Hemi-Sync helps them move more quickly and reliably into a meditative state. Experienced meditators also report that they seem to “go deeper,” and sustain the meditative state longer when using Hemi-Sync.

Q: What if I don’t feel awake and alert after listening to Hemi-Sync?

A: Certain Hemi-Sync products are designed to leave you in a sleep state. However, if a non-sleep recording leaves you feeling a little “spacey”, here are some grounding techniques to try: slowly count down from 10 to 1; drink cold water; splash cool water on your face and neck; run cold water on your wrists; weather permitting, walk barefoot outdoors while you breathe deeply.

Q: How many times should I listen to an exercise to get the effect or benefit?

A: Generally, you will feel the influence of Hemi-Sync the first time you listen. However, some products are designed as a training series. These products typically work best when you listen multiple times to reinforce and anchor the intended benefit. All Human Plus selections and the Gateway Experience series fall into this category. Specific listening instructions are included with your purchase of these items.
