The Power Of Binaural Beats
Find out what binaural beats are and if they work. Learn if it is possible to use them for massive change in your life.
Below I have givene a explanation of binaural beats technology. I have tried to include the science as much as possible while ensuring the information given is easy to understand.
It is now time to get a full, clear explanation of binaural beats and learn how you can use them to better your life.
Binaural beats are just tones which are generated to have a specific frequency and when listened to they can entrain your brain. Brain entrainment is just a fancy term used to describe what happens when a technology, such as binaural beats, is used to alter your brainwaves. Changing your brainwave patterns has many benefits such as promoting deep relaxation, heightened creativity and even a sense of happiness as well as having immense health benefits.
Binaural beats were first discovered by Heinrich Wilhelm Dove in 1839. Dove used 2 tones which were different only in frequency and only by a small amount. He then played one of these tones into one ear and the other tone into the other ear. This, he found, created a beat effect in the brain of the listener even though no beat actually existed. The brain perceived the beat when it mixed the 2 sound together. The beat had a frequency equal to the difference between the two tones. For example if one tone had a frequency of 1000 hertz and the other had a frequency of 1020 hertz the binaural beat produced would have a frequency of 20 hertz - the difference between the two tones. The beat itself does not really exist. It is merely the brain’s perception of what it is hearing that causes these binaural beats. They do not exist independently of the brain. Think of hearing a whisper on the wind, or seeing shapes in clouds - these things do really exist but your brain puts meaning to them!
Although this was a great discovery it wasn’t until 1973, when Gerald Oster’s article “Auditory Beats in the Brain” was published by Scientific American, that the enormous benefits of using binaural beat technology became apparent. It was found that when these binaural tones are played the brainwaves of the listener will follow the frequency of the beat that is produced. It is now known that certain frequencies are conductive to different internal experiences. If your brainwaves are between 8 - 12 hertz, for example, you are said to be in the Alpha state. The ability to entrain the brain into different states is highly beneficial. Let’s take a quick look at the common brainwave states and their associated physical states to get some idea of what I mean.
1. Beta - you are in the beta state when you are engaged in thinking activities, anxious or stressed.
2. Alpha - this is the state of relaxed focus. You would be in an alpha state if you were watching a movie or daydreaming, recalling memories.
3. Theta - this is the state of sleep, very deep relaxation or most forms of meditation.
4. Delta - this is the state of very deep sleep where the body repairs itself and the immune system is strong.
Each of these states has corresponding benefits. If you wish to be alert and want to be active then the beta state would be best. If you wanted to relax, learn new information or reprogram your beliefs then the Alpha state would be the most appropriate. If you want to create real change in your outlook, release past negative memories/emotions or just want to drift off to a sound sleep then entering the Theta range would be the best choice. If you need to accelerate your healing, strengthen your immune system or undertake some powerful self improvement work then the Delta state would prove highly beneficial.
Here are the frequencies associated with the brainwave states mentioned above:
1. Beta - 13 - 25 Hz.
2. Alpha - 8 - 12 Hz.
3. Theta - 4 - 7 Hz.
4. Delta - 1 - 3 Hz.
Many people wonder why they can’t just listen to the desired frequency without the need for two separate tones. This cannot be done as we can only hear sounds that are between 20 and 20000 hertz. Therefore frequencies that fall in the range of the desirable states, that we wish to create, would just not be heard if they were played as one track. As the tones used in binaural beats recordings create a beat that doesn’t really exist, this problem is avoided. In addition, the binaural tones, that cause the beat, have the added advantage of increasing communication between the two cerebral parts of the brain.
