Q: What is Hemi-Sync®?

A: Hemi-Sync® is demonstrated in a simple way by placing a steady tone in one ear, then a different steady tone in the other ear. As these different tones are blended together in the brain, the binaural beat or wavering sound you hear is a brain-produced phenomenon. Such signals can stimulate specific states of consciousness, which are automatically learned and can then be recreated from memory. More

Q: Is it important to have the earphones on the correct ear as instructed on some of the exercises?

A: No. As long as you are using stereo equipment, the intended effect will be achieved. Be sure your earphones are comfortable.

Q: There's noise on my tapes. They all have a hissing sound which I can only partially filter out with the Dolby® switch on my stereo. Are my tapes defective?

A: No. The hissing or "tape noise" sound is intentional. It's known as "pink sound," and provides a bed for the Hemi-Sync signals. Pink sound contains all the tones the human ear can perceive. The higher and lower portions of the sound have been adjusted so you hear the entire sound equally. This helps the mind create or select sound to complete the Hemi-Sync process. DO NOT use Dolby® or other noise reduction systems as they interfere with the sophisticated Hemi-Sync® process.

Q: What is the difference between hypnosis and Hemi-Sync®?

A: People often regard hypnosis as a process of being led into a state of high suggestibility and relinquishing control to the hypnotist. On the other hand, Hemi-Sync is designed to allow the individual to consciously control and manipulate his/her own states of awareness. With self- or auto-hypnosis, the individual relaxes him/herself, moves to a desired state of awareness, and consciously directs the exercise. Although similar in this regard, Hemi-Sync, with its special frequencies, assists the listener in achieving the desired state of consciousness much more quickly. It also opens the way to states of consciousness far beyond hypnosis.

Q: Is the "clicking" sound on some of my tapes normal?

A: No. If you hear disconcerting clicking or popping sounds on a tape (versus the "tape hiss" or "tooth brushing" of the pink sound), it may be defective. First, be sure the clicking is on the tape and not coming from your tape player. If you have a defective tape, return it to us for replacement at no charge.

Q: Does Hemi-Sync® still work if I use them from an Ipod?
Does the format ( MP3, AAC, etc..) of compression matter? I use a Mac.

A: Our own independent listening tests reveal that the Hemi-Sync® process stays intact when recorded to a different format. However, we currently have not explored how much loss of sound quality or degradation of frequency output occurs (if any). We prefer to use the CDs whenever listening, as do most Hemi-Sync listeners, because they produce crisp sound quality and we are assured of full, unfettered frequency output.

Q: Are Hemi-Sync tapes subliminal?

A: No. "Subliminal" implies that a specific verbal message is recorded below audible level and often at high speed. The intention is to embed a particular thought in the mind of the listener. By comparison, Hemi-Sync signals, although recorded at a sub-audible level, are not verbal messages and are not recorded at high speed. The intention of the Hemi-Sync signals is to assist the listener into a state conducive to the development of self-directed experience. Several Hemi-Sync tapes contain sleep periods during which verbal guidance is recorded at a very low level so as not to awaken the listener. The script during these periods is a repetition of the information heard previously on the tape.

Q: How can I convince a skeptic that Hemi-Sync is worth trying?

A: Without interest and desire, the openness that leads to success will be lacking. In other words: There is no such thing as convincing a skeptic. It would be better to let your own personal growth speak for you. As you become calmer, more centered, more confident, more creative, more intuitive, etc., people close to you will notice and will want to know why. It may be useful to emphasize what you have learned rather than the experiences themselves. When it is appropriate to describe your experiences, try to relate them to something familiar to the ones with whom you are sharing. Another approach is introducing a more mainstream Hemi-Sync exercise such as Catnapper or Concentration. Experiencing and discussing the practical benefits of Hemi-Sync in daily life can build a foundation for greater openness and self-discovery.
