What is Brainwave Entrainment?
In our fast-paced and interconnected world, tension is on the rise. Now, more than ever, the need to just relax, unwind and release oneself from mental and emotional stress has never been more important.

Stress and negative emotions can lead to real medical consequences and conditions.

According to the discoveries of Alfred Tomatis every bone, tissue and fiber of our bodies operates through its own unique resonant frequency which combined make up each individual person's unique vibratory signature.

Disease occurs when an individual's own natural vibratory state is out of resonance or is in disharmony.

The focus of Restful Tones is upon the healing of the body, mind and soul by means of slow tempo brainwave entrainment music and/or nature sounds embedded with certain frequencies known as binaural beats and isochronic tones.

Over time these frequencies can shift our vibratory frequency and consciousness to bring the body, mind, and soul back to a place of health and harmony.

About Brainwave Entrainment

Scientifically proven to improve your overall well-being

To understand how binaural beats, monaural beats, and isochronic tones can improve your overall well-being a basic understanding of the electrochemical functions of the brain is necessary.

Our brain is made up of billions of brain cells or neurons which use electricity to communicate with one another. The combination of millions of neurons sending signals all at the same time produces an enormous amount of electrical activity in the brain. This activity can be detected and mapped using EEG devices. Such mapping shows that the brain is emitting specific frequency brainwave patterns that relate directly to different mental processes all the way from wide awake and highly focused (beta) to deep, dreamless sleep (delta).

Below are the 4 most common brainwave classifications as revealed by EEG devices. The brain is a dynamic, living organ. During these dominant patterns, other frequencies still exist and there is no exact, single frequency that our brain operates on.

Beta - Throughout the day our brains are in the beta range with a frequency of about 12hz and up. At this level we are active, busy, and all our emotional responses are at this level. People who are over active, or often depressed, irritable, angry etc., often lose out on the recuperation and recharging that takes place when we are relaxed in the alpha, theta, and delta levels.

Alpha - When we begin to relax and begin to get drowsy, but are still awake and conscious (maybe at pre-sleep) we are said to be at the alpha level which is about 7hz-13hz.

Theta - When we dream, or are in deep meditation, we are at the theta level (4hz-7hz).

Delta - During deep dreamless sleep where there is a complete loss of body awareness we are at the delta level (0-4hz).

Detailed Brainwave Classification Chart.

By using EEG devices it has been scientifically proven that when external stimulus is applied to the brain it is possible to change the dominant brain frequency from one stage to another. This is called entrainment. For example if an individual in the beta stage (see chart above) with a brain frequency of about 20 Hz, is presented with a stimulus from the alpha stage of 10 Hz for some time, the brain frequency is likely to change from that of 20 Hz to 10 Hz - from a active beta state of mind, to a more relaxed state of mind at the alpha level. This is called frequency following response. This same example can be applied to going from a alpha state of mind to a deep theta state of mind and so on.

The technological methods used to entrain brainwaves (called brainwave entrainment) to desired beta/alpha/theta/delta states are known as binaural beats, monaural beats and isochronic tones, to name a few of the most popular. Additionally flickering lights can be used to entrain the brainwaves. Each of these different brainwave entrainment methods have their own advantage in synchronizing brain activity to the desired brain states.

Defining Binaural Beats, Monaural Betas, and Isochronic Beats

Binaural Beats

Binaural beats require headphones if you want to see results. Binaural Beats work by broadcasting two separate frequencies in each ear. For example, if you want to tune your brain to a 7 Hz frequency, you could play 200 Hz in your right ear, and 207 Hz in your left ear. The brain will compensate for the difference between the two and produce a third tone that will be exactly 7 Hz. This will result in your brain frequency being lowered to the theta level of 7 Hz.

Monaural Beats

Monaural beats are the opposite of binaural beats because the input is the same in each ear therefore you don't need headphones but good speakers are always a plus. In the case of monaural beats the sound is the same on each side whether you use headphones or speakers, but the volume must be tuned precisely (not too loud and not too low) for the beats to be effective.

Isochronic Tones

These are sharper sounding than monaural beats thus they are more powerful in their effect on the brain and are believed to be the most effective of the three.

Binaural beats, monaural beats and isochronic tones by themselves are not very pleasant to listen to. This obstacle is overcome by embedding these beats/tones into soothing ambient music, nature sounds, the sounds of bells or chimes and so on.

Is Brainwave Entrainment Music Safe?

Just as it is not a good idea to stuff yourself with a variety of different foods all at once, or to exercise too much all at once, so likewise it is good to start with one recording, giving your mind time to adjust to that recording, before moving to another rather than trying to listen to multiple recordings every day. But there are some who should avoid listening to music containing binaural beats, monaural beats or isochronic tones. Generally speaking if you are prone to epileptic type events, pregnant, wearing a pacemaker, prone to seizures, or under the influence of medication or drugs, it is best to consult a physician before listening to recordings containing binaural beats, monaural beats, isochronic beats, as well as any recordings containing video of flashing lights (audiostrobe). It is also a good udea to NOT listen to these tyoes of recordings while under the influence of alcohol or other mood altering substances. Under no circumstances should you drive a car or operate potentially dangerous machinery while listening to brainwave entrainment recordings.

Brainwave Entrainment Can Help You Dramatically Improve Your Mental States & Abilities!

Recently, professionals in the areas of psychology, neurology, medical health and self-help have begun utilizing the power of brainwave entrainment in their work with patients and clients. Advances in the effectiveness of brainwave entrainment have been significant.

It is a relatively young but rapidly growing field that involves the study of how altering brainwaves naturally can allow people to easily enter states of increased intelligence, creativity, relaxation, pure energy and more! Researchers and scientists have found that different bands of brainwaves are associated with different mental states. Scientific studies have shown that brainwaves not only provide insight into an individual's mind and body, but they can be stimulated to actually change that person's current state. By causing the brain to produce or decrease specific types of brainwave frequencies, it is possible to bring about a large variety of mental states and emotional reactions.

How does Brainwave Entrainment work?

Here's the science behind brainwave entrainment: The brain is made up of billions of brain cells called neurons, which communicate with each other using electrical signals. All of these neurons sending signals at once produce a large amount of electrical activity commonly called a Brainwave pattern, because of its "wave" or cyclic-like nature. "Entrainment" is a principle in physics, where two cycles synchronize naturally with each other in order to work more efficiently. Entrainment is applied to chemistry, astronomy, electrical systems and much more, but can also be applied to the brain.

When the brain is provided with a stimulus, through the ears, eyes or other senses, it emits an electrical charge in response. This is called a Cortical Evoked Response. These electrical responses travel throughout the brain to become what an individual sees and hears. When the brain is given a consistent, repeating stimulus, such as drum beats or flashes of light, the brain responds by synchronizing, or entraining, its electric cycles to the external rhythm. This is commonly called the Frequency Following Response (or FFR), and it can be used to effectively alter our brainwave patterns.

In the last 10 years, there have been great advancements in the field of brainwave entrainment as it relates to cognitive functioning. Studies have shown that the brains of many people are actually functioning at low capacity. By targeting the specific brainwave band that is related to states of intense concentration and strong focus, scientists have been able to help individuals improve their academic performance. Entrainment can also be used to induce states of relaxation and even deep states akin to deep meditation. This can have profound benefits for people who are seeking to perform certain types of work, art or even attain certain spiritual states.

Still Wondering Whether Brainwave Entrainment Really Works?

In 1999, the Journal of Neurotherapy published a case study conducted by Thomas Budzynski, Ph.D. In the study Dr. Budzynski used 8 college students who were struggling academically. After undergoing audio-visual brainwave stimulation, the students outperformed a control group and significantly increased their grade point average. The GPA for the 8 students continued to rise even after treatment was discontinued!

Drs. Siegfried and Susan Othmer found that neurofeedback brainwave training in the 15-18 Hz range can produce significant shifts in IQ score, particularly with people who are suffering from ADD/ADHD and other disorders. In cases where the starting IQ value is less than 100, the average IQ increase was 33 points! They also found significant improvements in memory, reading and arithmetic. In a one year follow-up, trainees showed major improvements in self-esteem, concentration and self-expression.

Binaural Beats and Isochronic Tones Are Two Ways to Alter Brainwaves

Binaural beats are the most recognized form of brainwave entrainment because it is the earliest. With binaural beats, a slightly different tone is presented into each ear. The tones then combine in the brain to form a pulse or "beat". The pulse heard by the listener is actually the difference between the two tones. For example, if the left ear is given a tone at 20 hertz and the right ear is given a tone of 30 hertz, then the listener will hear a beat of 10 hertz. And the brain will entrain to that rhythm.

While binaural beats are by far the most used form of brainwave entrainment, other more modern methods are quickly gaining popularity. The most promising of the new methods is Isochronic Tones. Isochronic tones are a somewhat less well known form of entrainment; however, they have proven to be much more effective. Isochronic entrainment uses a single tone that is manually spaced, turning on and off in a precise pattern. This actually enhances the effectiveness of audio entrainment.

Ultimately, the studies show that a new day has dawned. For those in pursuit of any type of self development, brainwave entrainment can offer an excellent array of benefits.

Decades of History Behind Brainwave Entrainment

by Jason Wentworth (Red Five Development, LLC)

Brainwave synchronization or entrainment is the process by which an external stimulus operating at a particular frequency can cause the human brain to increase brainwave activity at that particular frequency, thereby modifying cognitive functioning.

In 1934, photonic light stimulation ("Photic Driving") was shown to cause brainwave synchronization when researchers found that the strength of the Alpha brainwave, discovered by Hans Berger in 1929, could be driven beyond its normal frequency using flickering lights.

In 1942, tactile stimulation was shown to cause brainwave synchronization by Dempsey and Morison through repetitive tactile stimulus.

In 1959, auditory stimulation was shown to cause brainwave synchronization by Dr. Chatrian, where the brain waves responded to clicks at a frequency of 15 per second.

In the 1960's, brainwave entrainment (synchronization) was being used as a tool to entrain the brain for desired effects. The amount of anesthesia needed for surgery was reduced by photic stimulation by M.S. Sadove, MD. During dental procedures, less anesthesia, less gagging, less bleeding, and reduction in anxiety were reported by Bernard Margolis due to brainwave entrainment.

In the 1980's, brainwave entrainment was being studied as a tool for Serotonin and HGH release, headache relief, and general relaxation by Dr. Norman Shealy, Dr. Glen Solomon, and others.

In 1980, photic stimulation was shown to produce "cerebral synchronization" by Tsuyoshi Inouye and associates at the Department of Neuropsychiatry at Osaka University Medical School in Japan. These results were later confirmed by Dr. Norman Shealy.

In 1981, the book MegaBrain was written by Michael Hutchison, discussing the many uses of entrainment, from meditation to increased learning.

In 1984, audio-visual brain stimulation and in particular hemispheric synchronization were analyzed during EEG monitoring by Dr. Brockopp, who said "By inducing hemispheric coherence the machine can contribute to improved intellectual functioning of the brain."

In the 1990's, the potential for using entrainment with ADD and learning disorders was studied by researchers such as Dr. Russel, Dr. Carter, and others.

To the present day, brainwave entrainment continues to be studied. Steady research comes from the work of Dr. Thomas Budzynski, David Siever, Michael Joyce, and others. Research has been conducted into PMS, Chronic Fatigue, Chronic Pain, Depression, Hypertension, and a number of other disorders.

Many modern clinical EEG units now come with entrainment devices due to the promising results of studies done in the field of brainwave synchronization. Over 70 years of research back the use of brainwave entrainment. There are continually more professionals, psychologists, mental health clinics, trainers, teachers, and individuals who are finding brainwave entrainment to be a remarkably useful tool.
