Binaural Beats - An auditory illusion
Actually, when the brain is exposed to two different frequencies then one tone is produced by it which refers to binaural beats. These beats help in sort of hacking the brain to achieve the desired state. The brain is the powerhouse and controller of the body. It not only controls all the actions but also has a direct effect on your interest in performing these actions.
So, it is very important to maintain the state of the brain. This state can be controlled by binaural beats. The state of the brain can be easily altered without using any medicine or drug by listening to binaural beats and even a desired brain state can be achieved by varying the frequency of binaural beats.
These beats affect your response to different environmental behaviors, your daily routine, and even your sleep-wake cycle. You can use these beats to regulate your daily routine and mold your habits as per your needs.
In simple words, a binaural beat is an auditory illusion.
If a person hears a frequency of 470 Hz through his right ear and a frequency of 445 Hz through his left ear then he will actually hear a frequency of 25 Hz.
Brain wave states:
The brain produces certain frequencies which are called brain waves. When a person is active, alert, and consciously engaged, it means his brain is producing high-frequency brain waves. While a lazy and inactive person indicates low-frequency brain waves which is most commonly the state of rest or sleep.
You can control your brain wave state with the help of binaural beats. Now, different brain wave states and their effect will be discussed.
Delta:
This state refers to a frequency ranging from 1-4 Hz. As already mentioned, low range frequency refers to inactive state so delta state means deeply sleeping. Without active dreaming, this state is a time of healing and regeneration. You daily go into this state while sleeping. Especially when are feeling unwell, you will surely like to stay in this state a little longer so to let your body heal and feel comfortable.
Exposing your brain to two different frequencies whose difference results in one tone of above- mentioned frequency can let you achieve a delta state. The deep sleep cycle associated with the delta state varies in different age groups. With age, this cycle is reduced and at old age it almost becomes negligible.
Theta:
This state includes the frequency range of 3-8 Hz. This state is achieved before deep sleep and is associated with subconsciousness. This consciousness is not associated with this material world but with another sort of internal world. This state is characterized by dreaming and sort of similar awareness. Your suggestions, thoughts, ideas, and plannings shift to subconsciousness and you become unaware of what is going around you. Two different frequencies one from each ear after interpretation by the brain when the result is in a single tone of frequency range 3-8 Hz then theta state is experienced. This state is basically associated with deep relaxation in spite of deep sleep. In this state, you get to know a lot about yourself.
Alpha:
The frequency range of 8-12 Hz refers to the alpha brainwave state. It is high time to absorb and learn new things and make yourself adaptive to different situations. Unlike delta and theta which are associated with unconsciousness and subconsciousness respectively, this state is linked with half-consciousness and half subconsciousness. You don’t react to situations immediately rather you have time to process information and develop a format of your attitude. This is the best state for meditation or achieving focus. It includes daydreams, your own visualization, and concentration. Exposing the brain to two frequencies whose difference is in between the above mention range can let you experience an alpha brainwave state. Actually, this resulting tone refers to binaural beats and these beats create a resonance with brainwaves and provide strength to these states.
Beta:
12-38 Hz frequency range is related to beta state. Unlike all the above-mentioned states, this state refers to complete consciousness and awareness. A man in this state is fully active and can react immediately to suddenly changing situations. High-frequency beta waves can actually lead to hypertension and increased heart rate. A single tone of the frequency range as above, which is produced by two different frequencies, can synchronize with beta brain waves to enhance this state. These brainwaves need a lot of energy for their production and are widely produced during exciting activities. Sensory experiences are related to the beta brainwave state.
A safe and easy method of reducing high-frequency beta brainwaves is to listen frequently to alpha, theta, and delta state frequencies. These binaural beats, in this way, help to control heart rate and to reduce tension.
Gamma:
The frequency range of 38-42 Hz is included in the gamma state. This state leads a person to think that he passed through a spiritual experience. This state is not yet perceived completely. One thing associated with this state is universal love and harmony. This range is the highest frequency that can be experienced by a person but scientists do not say a lot about this state.
These are the stages through which a human brain can pass through and the relation of these states with binaural beats is also been discussed. Binaural beats help you achieve a state that is healthier and that you want to go through. It can also lessen the effect of others which is not recommended.
Effects of binaural beats on brain state:
Actually, the human brain can attain all the above-mentioned states by itself but binaural beats actually help in achieving the desired state and strengthening that state. These beats do not cause any damage to the human brain. In fact, they just power up the brainwaves and can also help in preventing an undesirable state. Binaural beats are helpful in
- Meditation
- Sleeping
- Studying
- Workout
These beats bring calmness and peace to the atmosphere in addition to bringing your favorable brain state.
