The human brain is a complex entity constantly at work, sending electrical signals, communicating, building new neural connections and so on. This electrical activity generated by the brain, also known as brainwaves, reflect our state of mind. Reality is not based on outside influences but is an internal process based on our thoughts, perception and emotions. If we deepen our understanding of these brainwave frequencies, we can control our reality. There are five different kinds of brainwaves – Beta, Alpha, Theta, Delta and Gamma.
It is completely a natural biological occurrence in every human being to experience these different states at various times in a day, and generally one state is dominant. Did you know that each brainwave has its own set of characteristics representing a unique state of consciousness? Each brainwave state occur in a specific frequency range measured in cycles per second (Hz). Each type of brainwave played a critical role in our mental development during our childhood. And today, they play an important role in maintaining our health and vitality as adults.
Altering Brainwave states
All of us experience these brainwave frequencies at different times every day, which take us to different levels of consciousness. Like when you are awake you are in a different brainwave state as compared to when you are sleeping. You can alter your brainwave pattern in order to reach a desired level of consciousness. For example if you can’t get sleep at night when you feel stressed, you can synchronize your brainwave into the frequency that corresponds to sleep using sound. This technique of synchronizing your brainwave frequencies to an external audio stimuli is known as Brainwave Entrainment. As this process is continued for sometime, the brainwave is tuned to the frequency of external sound and thus achieve the particular frequency level of that sound (alpha, theta or delta). But you don’t need external stimulus if you can meditate. During meditation you reach a calm and relaxed state, this is the alpha state of consciousness. As the meditation deepens you find yourself being more calm and focused and the brainwave level reaches to theta (and finally to delta) state.
How can a sound with frequency lower than 20 Hz range be audible to the human ear? The answer lies in a specialized sound known as Binaural beats. What it does is simple – playing two different frequencies in each ear, the brain detects the difference between the two frequencies and tunes into the third ‘binaural beat.’ So if you play 400Hz into the right ear, and 410Hz into your left ear (using stereo headphones) your brain produces a third binaural beat pulsing at 10 Hz, which is the difference between the two tones. 10 Hz is also equal to the alpha frequency, which brings about light relaxation, meditation, and creative thinking. Binaural Beats shall provide you some excellent results often instantly which will help you in many ways.
