specified frequency, these machines stimulate the brain wave activity of the
user, leading the user’s mind from normal waking consciousness to a variety
of altered states of consciousness.
BETA 13-30 Hz: Normal waking state; attention directed to surroundings. Includes
agitated, restless/”monkey mind” states which are especially amenable to
treatment with light and sound stimulation.

work of physicians, psychologists, therapists, body workers, any harried
professional, as well as the individual experimenter who wishes to explore
altered states of consciousness, awareness expansion and sensory
brainwave state (beta, alpha, theta, delta). The first thing to consider is: do you like to fiddle around with technology, or generally never use the
advance features of the equipment you buy?” If you like to fiddle around,
then look at the machines with the most features, otherwise look at the
minimal feature machines. Now go by your budget.
closed eyes and headphones over your ears, you are immersed in colorful
geometric patterns and entrancing sounds. The light and sound pulse rate
shifts from state to state as the session progresses; brain wave activity
will follow the pulse rate of the mind machine and fall into synch with the
relief, deep relaxation, assistance in falling asleep, memory improvement,
increased learning, stabilizing emotions, increased intellectual focus,
lucid dreaming, substance abuse issues, sensory
stimulation, increased physical energy. While some of these benefits have
been substantiated by research studies, these machines are experimental and
results will vary from person to person.
aural. Sound and music have been used for centuries in may cultures to
manipulate consciousness. Drums, chants, and environmental sounds like wind
and rain all provide strong mental pictures and associations. Pleasant
sounds are much more enjoyable and relaxing than one-note beeps or tones,
such as those used by other machines. Every system Mindmachines.com offers incorporates the most sophisticated sound generation circuitry of other light/sound devices.
most Mindmachines.com products. Using two sound synthesizers in the audio
circuit, and by specifying slightly different sound frequencies for the left
and right channels, it is possible to induce a third frequency which is the
difference between the left and right in the mind of the user. This is known
as a binaural beat frequency generation. The perceived beat frequency is
especially useful as an entrainment tool when paired with pulsing lights.
diodes–LED’s–are solid state devices that convert small amounts of electrical energy into light. They can be switched on and off much faster than incandescent lights, producing the crisp strobe-like pulses which have been shown to be most effective at inducing patterns of brainwave activity. They also create very pure colors–again an important factor in the alteration of consciousness and brainwave activity.
White LED or TENcolor lightframes are the best. An advantage when
working with the public is that the color white has no color associations
attached to it; it is clean. People’s personally experiences in life
radically filter one’s response to specific colors. If someone had very
negative experiences as a child and their room was painted green; green is
not going to have the traditional healing effect for that person. It is nice
to have color choices when working with the public to let them decide.
Basically otherwise, the warm colors (red, orange, yellow) have an
excitatory (stimulating) effect; and the cool colors (blue and green) have
an inhibitory (calming)effect.
sin(a) + sin(b) = 2*(sin((a+b)/2)*cos((a-b)/2)).
Interpreting the formula, beats are perceived as the average pitch (a+b)/2 modulated (pulsed) at the difference frequency (a-b). If you are paying close attention and noticed the disappearing 1/2, cos(a-b)/2 has two amplitude peaks per cycle, so the modulation is perceived to be at frequency (a-b) not (a-b)/2. When you listen to a mixture of slowly changing tones on a dual binaural beat instrument, fascinating beat effects are heard.
Chords are combinations of tones that (hopefully) sound harmonious. Harmony occurs when the fundamental pitches of the tones are in ratios of small integers, such as 2/1 (octave), 5/3 (sixth), 3/2 (fifth), 4/3 (major third), or 6/5 (minor third). Most people hear tones closer than a minor third as dissonant. When tones get still closer in frequency, beats occur.
Dual monaural beats occur when two closely spaced pitches are mixed in the same ear, beats are heard at the difference of pitches.
Fill-in-blanks is a technique of creating light and sound programs by selecting one of a number of available program profiles, and specifying the frequency range and control options to be used. Thus a custom program can be created with four menu selections.

Hertz refers to cycles per second, or how often something repeats itself within each second. Named for Heinrich Hertz (1857-94). Hertz is the primary measurement of sound, but is fast losing popularity to amplitude. Hertz used to be called “cycles per second”, meaning the number of times a repetitive event occurred per second. Then someone noticed that physicist Heinrich Hertz had no measurement unit named after him, so he was appropriately immortalized.
experience the session with eyes open. Recently, clear eye frames have been produced with low intensity LED’s that enable the user to experience light and sound sessions with eyes open, enabling the user to simultaneously experience the session while studying, working at computer workstations or during beta EEG/neurofeedback training.
Ramping is a gradual method of changing (either increasing or decreasing) the parameters of light and sound stimulation when designing a session. Ramping refers to changing a stimulation parameter gradually so that “jumps” are not perceptible. Most light and sound systems can ramp frequency, but some still “jump” in 1 or 2 Hertz steps. Fewer can ramp volume and intensity. Listen to a dual binaural beat session before deciding it is not important to ramp pitch.
Tone is the kind of sound stimulation used in light and sound sessions. Examples of tone are: pulsed tone, pulsed surf, alternating tone/surf, pulsed chord, binaural beats, binaural beats with a metronome tick at a specific frequency, dual binaural beats and dual binaural beats with surf. Tone refers to the type of sound stimulation used.
Volume refers to the loudness of the sound stimulation.
