HOW IT WORKS

BETA BRAIN TECHNOLOGY. HOW IT WORKS

THE BASICS


  • This audio technology was developed over two decades ago and is called by various names such as Binaural Beats, AHATA frequencies, MOH frequencies.
  • It is still a useful and easy way of learning to access the four basic brain states.
  • These brain states are called: Beta for concentration, Alpha for relaxation, Theta for changing behavior and Delta for sleep
  • The audio technology sends two slightly different frequencies separately to each ear.
  • The brain automatically splits the difference and gently moves to the appropriate brain state.
  • The pure-tone frequencies are very boring to listen to so are “quilted” with neutral sounds such as running water and mist.
  • Unless you are currently receiving treatment for epilepsy the sounds are quite safe to use.
  • A few companies around the world include the technology in various forms in different programs.

COMMENTARY

Since the nineteen fifties, scientists have been able to measure and plot the very weak electrical currents exhibited by our brain with the Electroencephalograph, or EEG machine. This showed that various parts of our brain had different frequencies, depending on our mental activities. With advanced computer capability, even simpler versions, such as those used in Neurotherapy, give insight as to how the brain varies in its levels of electro-chemical activity according to the use it is being put at the time. In other words, your brain and specific parts of it, change in response to the needs. And it is in assisting the matching of such responses that MOH Frequency technology has been found to be very useful.

Most of you will be aware of the notion of the two halves of the brain having different functions. The left-brain seems to be the logical, analytic side of our thinking process while the right brain is the creative, non-logical side.

In addition, the various brain states were given Greek letters as follows:
The wide-awake state was termed Beta, (12.0 Hz – 40 Hz)
The dreamy state is called the Alpha state, (8.0 – 12.0 Hz)
The state we pass through as we fall asleep and as we awaken is called the Theta state, (4.0 Hz – 8.0 Hz)
And the state most of our brain reaches during sleep is called Delta. (0.5- 4.0 Hz)
The numbers associated with these broad states are given in Hertz, which is the number of vibrations per second. Note that there is no zero Hertz; at zero Hertz we would say that the person is brain-dead.

Range of Hearing

Now, on a related topic, if we consider the range of sound waves that our ears and auditory system can process, we find that the range is roughly between 50 Hz and 20,000 Hz. And if the maximum of our brain waves is about 40 Hz then there is no overlap between the brain vibrations in Hertz and the range of our hearing in Hertz. It would seem, then, that there is no way to directly influence the brain with sound waves.

But as we know, humans have always used music and other sounds as a means to influence each other: for example, lullabies to quiet us down, drums and keening bagpipes to stir us up for battle.

Heterodyne and Two-ear effects

Starting with Pythagoras, scientists know that sound waves behave in a mathematical way. For example in 1795, an Italian violinist, Giuseppe Tartini, discovered that if you play two similar tones together you could produce two softer tones, one lower and one higher. But apart from assisting musicians to tune their instruments there seemed to be little use for these Tartini Tones, as they were called.

As measuring techniques improved, sound technicians found that if you take, for example, a pure tone of 104 Hz and pass it through an audio mixer together with a pure tone of 100 Hz, four separate pure tones will emerge. These are: the original tones of 100 Hertz and 104 Hertz, and another tone called the summation tone being the addition of the two and another one called the difference tone, which, as it states, is the difference between and 104 and 100. This confirmed Tartini’s idea and the phenomenon was termed the Heterodyne Effect. It’s a monaural effect. That is: you can hear it with one ear only.

The two-ear effect was discovered, way back in 1839, by a German scientist called Dove. He found that the human brain seems to act similarly to the audio mixer, but it also has a two-ear effect, hence the term, binaural beats. Tones sent to separate ears are combined and a Difference Tone is produced inside the brain. Little use was seen for his discovery, but in the nineteen fifties researchers noticed that this difference tone was in the range of the brain frequencies and suddenly a practical use for the phenomenon was presented.

Let us give you an example of this:
We take a pure, computer generated tone of say 220 Hertz, also known as middle A and play it from one side it will sound like this.
(Click.)
If you have stereo equipment click left tone for a 2 second clip.
Now if we play the same tone on the other side it sounds like this. (Click.)
If we play them together, we will hear the same pure tone in the center, like this.

The Off-set Frequency

Now we will create an “Offset Frequency”
First we play on one side, say C#, or 277 Hertz which sounds like this. 
(Click.)
And on the other side D, or 293 Hertz like this. (Click.)
Now if we play them together listen to the effect.

Frequency Following Response
The wavering in the centre is being constructed in your own brain; it is not coming from the speakers or the earphones. This is the Binaural Beat effect, but we prefer the term Offset Frequency as it better describes the process. The offset frequency in this case is 16 Hertz, which will keep you wide-awake for concentration and study. It is these capacities of the human brain to blend the frequencies heard from different ears that can, very gently, affect our brain sates.
It seems as if the effect produced by the offset frequencies gently flows to other parts of the brain and the person experiences different mental states. The effects were tested first to help people fall sleep. Then a number of other different brain states including concentration and creativity were produced. We do not know exactly how this operates, at the neurological level, but studies using the PET scan may yet show us the process.

The principle of the brain passing on frequencies to other parts of itself is called the Frequency Following Response.
Those who are familiar with tuning forks will know that if you take a tuning fork of particular note and place it near one that is already ringing, if the note of the forks are of the same frequency, the smaller one will begin the vibrate, as it were, “in sympathy” with the larger one. If, however, the tuning forks are not of the same note, no sympathetic resonance will occur.
It seems as if the brain acts in a similar way: If sound waves are created in one area they tend to find a sympathetic resonance in another area. This is all very gentle and can be stopped by the intervention of the conscious mind.

The principles of Off-set Frequencies and Frequency Following Response, are two of factors in the MOH Frequency programs. Of course, specific combinations of pure tones are used by the technicians to create the various brain states required.
The key is the harmonic blending of two or more sets of off-sets to produce, for example, the FOCUS frequencies, which assist the listener to a RELAXED but WIDE-AWAKE state.

Another example is the achievement of the Theta brain state. Because this is very close to the sleep state one usually is not aware of it, but with MOH Frequencies we are able to take the listener down to the Theta state and hold them their for a while. This enables them, in a strange way, to be aware of what the subconscious mind is presenting to them. In saying this we well know that the human brain is a vastly more complex arrangement than we have suggested above. But it seems that, if the brain’s “Security Guard”, the Reticular Activating System, accepts the frequencies as benign, then the effects are usually experienced.
Sound Quilts

Practical application of these principles of MOH frequencies showed that we humans soon get bored with hearing the same pure tones without variety. So technicians cover them over, with a sound “quilt” of a familiar sound such as the sound of the ocean surf or sometimes the restful sound of a bubbling brook. 

Or sometimes when you really want to access your inner thoughts, or concentrate, we sometimes use what we call Blue Mist. (Click) to hear the Blue Mist sound sometimes called MISTY.
Systems that use the quilt itself to produce the offset frequency do not seem to be as effective as the combination offset pure tone plus different sounding quilt.

MOH Frequency programs also incorporate various appropriate sound effects and commentary. The commentary, or storyline, gives the listener’s logical left-brain something to do. Thus, for example, in the Sleep Starter, with the logical brain busy with the story, the whole brain can relax and move through the Alpha to the Theta and then to the Delta sleep state.
Safety
 
With the exception of those who are CURRENTLY on medication for epilepsy these programs are quite safe to use. They form part of the whole concept of BRAINWAVE Training, which is encouraging and training the brain to move to the ideal states for various activities. As we all know there at times when we just do not feel like doing what we need to do. Another way of understanding this is that our brain is in an inappropriate state. Helping it to the ideal state is the first big step in doing what you need to do. This capability has been used with excellent practical benefits in the programs for study assistance.
