Change Your Brain With Binaural Beats
I first came across binaural beats while living in a small one bedroom apartment with my wife. The living room also doubled as the office and I needed something to block out the television noise while I worked on the computer.
I dug out my headphones and began searching YouTube for some soothing sounds. What I found was a curious list of something called binaural beats. There were hundreds of different audio clips promising such things as improved concentration, relaxation, sleep aid, and so on.
For months I experimented with the different frequencies. The white noise they produced provided a nice distraction and I did notice that I was more focused while working. I didn’t know how these strange sound waves worked; all I knew was that they did what they claimed they would.
I decided to do some research.
What is a binaural beat?
Binaural beats were first discovered in 1839 by physicist Heinrich Wilhelm Dove. What he found was that when the brain is presented with two different frequencies (one in each ear), it will create a third signal which sounds like a beat. This newly created frequency, when measured in cycles per second, will be the exact difference between the original two frequencies.
For example, if a frequency of 100 Hz (hertz) is played in your right ear and 105 Hz is played in your left, your brain will manifest a third frequency of 5 Hz, the exact difference between the two.
Do you believe that listening to sound waves can affect your mood?
How does this affect my brain?
First let me quickly explain what brain waves are and how they work.
A fully functioning brain can generate up to 10 watts of electrical power. That is because the billions of neurons that make up your brain are ceaselessly using electricity to communicate. Day and night, these little cells transmit signals to each other regardless of your state of consciousness. They can communicate to each other from distances of up to several feet away!
This electrical activity in the brain shows up as brainwave patterns and they change depending on what you are doing at the moment. For example, someone who is wide awake will have a different brainwave pattern than someone who is sleeping.
There are five categories of brainwaves and they are measured in hertz, which is the equivalent to cycles per minute. One hertz equals one cycle per minute.
The waves and their frequencies break down like this:
Gamma waves (27hz and up). These waves are associated with high level information processing, learning, and the formation of ideas.
Beta waves (12-38hz). These are the brainwaves of our “normal” wide-awake and engaged state.
Alpha waves (8-12hz). Awake but relaxed, as in meditation.
Theta waves (3-8hz). These waves are associated with light sleep or extreme relaxation such as hypnosis or day-dreaming.
Delta waves (0.2-3hz). These waves are known to occur during deep sleep.
By creating a binaural beat between your ears, you can alter your state of mind. The beats are specifically designed to work within the above mentioned frequency ranges. Therefore, by inducing a frequency of 8hz you can mimic the brain activity found in a meditative state.
If you needed help falling asleep, you could try creating delta waves.
It generally takes several minutes of listening to these sounds through headphones before your brain begins to change direction and march in-step with the newly created pattern. This process of manipulation is known as: the frequency following response.

Benefits of binaural beats
The ability to quickly and easily choose your state of mind can be incredibly useful. Find a beat to help promote any of the following:
● Mental focus
● Pain relief
● Deep sleep
● Meditative state
● Simulation of drugs
In addition, it is possible to synchronize the two hemispheres of the brain using binaural beats. This powerful phenomenon occurs when the electrical activity in both the left and right side of the brain resonates at the same frequency and occupies a much greater area between your ears. The result is known as: whole brain synchronization.
This enhanced level of performance in the brain is normally only found in moments of heightened creativity and inspiration. Now you can achieve it within minutes!
About the tones that are used
The two different tones used to create the beat are known as carrier tones. For a true binaural beat these two tones must be pure, smooth, and unmodified in order to hit their desired frequency. The sound waves used to achieve this are called sine waves. They are known for their smooth, repetitive oscillation.
Some binaural beat sessions are overlapped with soothing sounds such as ocean waves, or falling rain. These sounds can be a pleasurable addition to the otherwise monotone white-noise.
No matter what state of mind you wish to achieve, there is a binaural beat out there to suit you. So grab your ear buds or your headphones and plug in to this safe and inexpensive sound therapy today. You’re going to love the results.
