Binaural Beats Explained – How They Are Created And How We Perceive Them

We are all aware that an unborn child is capable of hearing. Our sense of hearing begins long before our sense of vision. As such, sound becomes a powerful form of stimulation for achieving desired brainwave states. Sound stimulation can come in many different forms. Some of the most common include: surf or pulsed white noise, pulsed tone, white noise and tone combined, pulsed chord, binaural beats, dual binaural beats and white noise with either binaural beats or dual binaural beats.

Nearly all light and sound instruments are capable of generating white noise. You know that fuzzy sound your television makes when you are between channels? Or the sound rushing water makes as it flows by you? That’s what pulsed white noise sounds like. Pulsed tone is just like white noise except a pitch is utilized. Your light and sound instrument should have the ability to let you adjust the pitch.

Combining pulsed tone to pulsed white noise is often used in “entertainment” sessions for creating special sound effects. A pulsed chord is basically the combination of two pulsed tones that are set apart at musical intervals.

A binaural beat is the combination of two audio frequencies or tones. One tone is directed to the left ear while the other tone is directed to the right ear. Say the left ear is receiving a tone of 180Hz and the right ear is receiving a tone of 190Hz. What the brain actually “hears” is 10Hz, which is the difference between the two and is known as the offset frequency. Dual binaural beats are created simply by combining two totally independent binaural beats. The resulting four channels of audio beats work together to generate several offset frequencies. The resulting frequency variations are very dynamic and complex, and have become the ideal method for maximizing brainwave entrainment. In fact, dual binaural beats are so effective that listeners can utilize stereo speakers rather than headphones and still receive the full effect. White noise is sometimes combined with either binaural beats or dual binaural beats. This method is limited, however, to session designs targeting relaxation and meditative states.

Phase settings for pulsed tone and white noise are connected to the light settings. By combining sound with light, you can utilize eight different phase settings: in phase, out phase, cross phase, sound out phase with lights in phase, sound in phase with
lights out phase, clockwise motion, counterclockwise motion and front/back phase. All phase settings are rather self-explanatory and are described in more detail in the owners manual of your light and sound instrument. Phase settings with dual binaural beats
involves a little math and some experimenting. For information on creating sessions utilizing binaural and dual binaural beats, see “Mind States / An Introduction to Light & Sound Technology” by Michael Landgraf of

About Lightframes ( AKA Light Glasses – LED Glasses ) for Your Mind Machine

What looks to be two identical lightframes have different polarities, the lightframe RCA jack is too big for the light port of the mind machine, how come some lightframes connect with RCA jacks and others have mini-USB connectors? Often happens when you use one manufacturers mindmachine with another manufacturers lightframe. Manufacturers design mind machines, light emitting eye frames and various other accessories that fit their vision of what a light and sound machine should look like and it?s built-in software abilities. Get the type(s) of lightframe made for the mind machine you own. Wasn?t always like this, but as the technology advances so does a manufacturers ability to seek perfection. And that?s a good thing, but what?s so important with lightframes? Color and comfort matters.

Back in the 1980?s, when I was first turned on to a light and sound system, the lightframes were red LEDs. To my mind, the red stimulation produced a black background three dimensionally filled with some of the most radically colored patterns and visuals ever created. Yes, the frequency sessions affected my mental, emotional and physical state of being, but my brain was tuned to the visuals and music I had playing. It was great. Better than a brain tune-up.

Today there are so many lightframe variations and so many choices. If this is going to be your first mind machine and you would prefer starting with one type color stimulation, go for the white lightframes. The visuals they produce can get outrageous, having a profoundly positive effect on your state of mind.

Considering neurotechnology affects the mind and most newcomers to light and sound know very little about how exactly, it is best to have information describing the color aspect of light and sound mindmachine stimulation. The more you personally know about this technology, the better the choice you will make when choosing a mind machine that will best meet your own personal needs.  

Everybody has a favorite color, like wearing khaki pants or a green shirt, perhaps the walls of your home are Navajo white, maybe even a mixture. Then there is that subconscious element to consider, like if you were in an auto accident and you were driving a blue car. Would blue still be your favorite color or would it conjure up negative feelings stemming from that unfortunate event? Lots of variables enter into deciding what color you would be happiest with.

Red may be a ‘warm’ color, often thought to be more appropriate for beta sessions, but not necessarily. Red LED lightframes, when used with your eyes closed, stimulates the cortex of your brain into generating some of the most delightful shades, blends and swirls of colors possible. Red LED stimulation can help you relax.

Yellow, orange and red are viewed as ?warm? colors and are stimulating (excitatory). These LED color lightframes are often utilized when experiencing sessions containing higher frequencies such as beta. ?Cool? colors like green, blue and violet are calming (inhibitory). These colors are most often used with sessions having lower frequency stimulation, all targeting the deeper brainwave states known as alpha, theta and delta.

Although any color of light would deliver the benefits of a light and sound session, specific colors will help get you there faster, even more deeply. When you are considering the various colors, wondering which color would best apply to your situation and what a particular color is normally associated with, here is a generally accepted generic guide: use blue color stimulation for delta (sleep / clearing); use green for theta (meditation / visualization); for alpha (learning / relaxation) use yellow; and for beta (focus / energy) use orange or red.

Here are three different methods for producing pulsed light stimulation. Most manufacturers use LED bulbs, incandescent bulbs and RGB-based LEDchips. The LED style is better than the incandescent variety. Incandescent bulbs tend to have a bleed-over effect at higher frequencies, they just can?t turn on and off (blink) efficiently at high rates. LED bulbs can. The LED-based chips are even better. 

Left and right color independent eye control gives you greater control of the pulsed light stimulation. It allows you to simultaneously activate or relax either your left or right brain hemisphere. With no means of eye control, the pulsed light stimulation being generated affects both hemispheres of the brain equally. For overall calming or energizing, that is fine. But what if you wish to work on your right hemisphere, not your left, and vice versa? That?s when having this control proves advantageous. Simply stated, if you would like to activate the right hemispheric region of your brain, but not the left, select a warm color (yellow, orange or red for instance) for the left eye of the lightframe and for the right, select a cooler color (such as violet, blue or green).

 Even though we all think and are affected differently by pulsed light stimulation, certain colors appear to work best, in a generalized kind of way, for helping to enhance certain abilities or to achieve certain sensations and emotions. Based on what I have read, personally experienced and received as feedback from my customers these past twenty-plus years, here are the most common colors for pulsed light and what they are used for:

 Red – invigoration, extroversion, strength, activity, vitality, energy, action. Red provides a wide range of colorful visuals for most people.

 Orange – subconscious, relationships, interaction, creativity, change, sexual, social. Although soft and subtle, orange can invigorate and energize the light and sound listener. Sometimes referred to as the color Amber, it falls between red and yellow. If you find the color red too intense and green too dim, try this color.

 Yellow – concentration, learning, thinking, idealism, memory, sunny, focus. Yellow is highly recommended for soft , yet subtle light and sound experiences. The color yellow is considered to be excellent for use while studying.

 White – effective for working with imagery, relaxation and visualization. White generates a richness in colors and sense of dimension that no other pulsed color can imitate. White can attain a brightness intensity similar to red while generating color pulsations that appear to float before your eyes. White light is the most popular color used, offering full spectrum stimulation to ensure that the red, green and blue cones of the retina receive full stimulation similar to the natural light spectrum.

 Green – compassion, revitalizing, peaceful, renewal, calming, balance, healing, love. Preferred by those experiencing certain degrees of light sensitivity. The color green is associated with nature and with heightening the emotional qualities of the heart.

 Blue – use for communication, contemplation, contentment, meditation, relaxation, sensitivity, creativity and sleep. Blue will generate a profound sense of calmness and a feeling of deep relaxation and is believed to contribute to the creation of ordered thought and harmonious moods.
