The Listening Experience
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 noise” (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 noise enhances the perception of the Hemi-Sync® sound patterns, and therefore plays a valuable role on certain Hemi-Sync® products.
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.
Q: What kind of equipment is required to listen to Hemi-Sync®?
A: A moderately priced stereo player, including portable CD players 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 SleepPhones, which are designed to be used while lying down in any position. You can also try earbuds, which are designed to fit comfortably inside the ear. Alternatively, use conventional speakers placed on either side of your bed, or try a stereo sleep pillow.
