A Brief Introduction to Binural Beats


Discovered by H. W. Dove in 1839, it wasn’t until 1973 that Robert A. Monroe and his team introduced binural tones as a way to influence human consciousness. Binural beats are a unique form of music that uses separate tones to create a desired effect. It works like this… Through a set of stereo headphones, a tone of lets say 50 Hz is played into the left ear only. In the right ear a separate tone of lets say 60 Hz will be played at the same time. When listening to these two separate tones in each ear, a 3rd wavering tone will be created inside of your head. This wavering tone is not coming from the speakers but is being created by you. The 3rd wavering sound is the binural beat and in the example given above, would be a sound of 10Hz which is the difference between the two original tones. A binural tone is a standing wave that is produced by the brain and is only possible due to binural hearing. Remarkably, even after listening to these binural tones, your brain can still maintain the standing wave over a period of time.

Hemi-sync technology was created in 1975 by Robert A. Monroe founder of the Monroe Institute located in Faber, Virginia. Hemi-Sync stands for Hemispheric Synchronization which simply means a synchronization of the brains two hemispheres, the left and right sides of the brain. The Hemi-Sync tech is a powerful sound technology that consists of different combinations of binural beats, musical instruments, sound effects and / or verbal instructions. Each has a different effect, based upon the different programs and the way they are used. With Hemi-Sync you have the option to focus your brain towards peak performance through brain synchronization, as you can relax into a deep meditation or simply get a restful night of sleep. Hemi-Sync increases the connection and function between the two sides of your brain. Hemi-Sync gives your nervous system stimulus in the same way a workout would for your physical body. Using the Hemi-Sync technology can increase your mental and emotional threshold as well as your intelligence and creativity. Your brain creates new neural pathways as it adapts to the Hemi-Sync tech. Today there are hundreds of different Hemi-Sync programs available to assist you in obtaining the many different states of consciousness, currently available through the Monroe Institute and the Hemi-Sync website.

Brainwave States

Nerve cells in your brain generate electrical impulses that fluctuate in distinct patterns called brain wave patterns. These patterns include your thoughts, emotions, and bodily functions. There are 5 categories of brainwave patterns. Alpha, beta, delta, gamma and theta states.

Gamma (38 Hz — 42 Hz) Brainwaves are the quickest of all the brainwave states. Initially dismissed and extra brain noise, until it was discovered that Gamma waves are in fact active when in states of the higher conscious such as universal love. Gamma is above the frequency at which your neurons fire so how it is generated still remains a mystery to this day.

Beta (12 Hz — 32 Hz) Is seen as your normal waking state of consciousness, experienced during times of high mental and physical activity. Associated with concentration, arousal, alertness and engagement such as decision making and problem solving. While on the opposite end, the higher levels of beta can be associated with anxiety, disharmony, or unease.

Alpha (8 Hz — 12 Hz) As your brainwaves slow they enter an alpha state. Relaxed but alert, alpha is between the stages of being asleep and awake. The lower range of alpha is a state of deep relaxation, while the higher end of alpha is a more focused yet still a very relaxed state to be in. Calm but engaged, when you are watching an enjoyable movie at your local cinema, then you are probably in the alpha state. Alpha is most often associated with super learning.

Theta (3 Hz — 8 Hz) Waves are even slower than alpha. Trance, hypnosis, dreaming sleep and deep mediation are considered theta states. Associated with increased creativity, memory abilities, and forms of super learning. Those moments where a great idea or a flash of incite suddenly comes to you are theta states. the self sabotaging parts of the left brain are bypassed in the theta state. In the lower theta state the brain makes lots of relaxing endorphin’s that can bring mild visions or simply melt your stress away.

Delta (.5 Hz — 3 Hz) The slowest brainwave pattern often associated with deep sleep. People are most often sleep while in this state but there is evidence that those highly skilled in meditation can obtain the delta state while staying awake. Healing and regeneration are stimulated in this state. And in certain delta frequencies the brain releases many highly beneficial substances, including human growth hormone which helps to fight age associated diseases and keep you younger.

As your brain slows from Beta to Alpha to Theta to Delta, the balance between the two hemispheres of your brain increases. This balanced state is called brain synchronization or hemispheric synchronization. What this means is you are now using both sides of your brain to think instead of just one. It gives you increased creativity, learning abilities and enhances memory, helping you to become less self conscious and function on a more intuitive level. With the increase in mental power and abilities, you can tap into remarkable potential that you never even knew existed.

How to Listen to Binural Beats

The most effective way to enjoy binaural beats are through stereo headphones. Speakers work great as well if you are playing the binaural beats for a large group of people, but headphones are always the best option. This is because different sounds are sent through the left and right sides of the headphones, so with speakers there may be some overlap between the different sides. Having separate speakers for each ear without interference is the most beneficial way to listen and better facilitates hemispheric synchronization. If you are going to use speakers instead of headphones make sure to sit near the center of the speakers for the best results. And remember lower is usually better. You don’t need to blast the tones at full volume when you are trying to relax into deeper states of consciousness.

Even though there are many benefits gained from listening to binural tones, one should be cautious when listening to and downloading these audio programs over the internet. You just don’t know how these sounds were mixed, and they might even have an adverse affect on you. Unlike the Monroe Institute where all of their Hemi-Sync music has been tested and perfected over many years of trial and error. So please exercise caution when you are listening from unofficial sources.
