Ever since he discovered information about the Earth Resonance Frequency (ERF), Dean Evenson has included that sub-audio tone under the mix in his healing music albums. We’ve had lots of requests for more information so here is some background on why it is such an important frequency and why we use it.
Our physical body is affected by vibrations that are below the range of hearing. One ‘ultra low frequency’ is called the Earth Resonance Frequency (ERF). This common frequency of our beautiful planet is located primarily at 7.83 Hertz or cycles per second. One reason we are interested in this frequency is because it is very similar to the frequency our brains emit when we are in the Alpha brainwave state. There are several factors at play here and we will share our understanding of the scientific basis of resonant frequency and explain how that ties in with the state of our consciousness. We will also describe how the ERF or other ultra low frequencies can be used in music to support reaching a meditative or healing zone more easily.
It may be more than coincidence the Earth Resonance Frequency of 7.83 Hz is similar to the frequency our brains emit when we are in the state of consciousness right on the cusp between the Alpha and Theta brainwave states. As you may know, our brains emit ultra low frequency sound waves that vary depending on the state of our consciousness. When we are in our busy, rational frame of mind, our brains emit Beta frequencies in the range of 14-20 Hz. This is called our Beta brainwave state and occurs when we are active and thinking, doing computer work, driving a car, or something that requires left brain thinking. We need to access this state to function in the world on a daily basis.
When we are seeking a space to meditate or heal, we want to drop down into the next state which is deeper and more relaxed, so we enter the Alpha state. This is when we are awake and alert but very peaceful, calm and centered. The Alpha range is around 7-14 Hz. and is a very safe state to be in because one is still awake and alert to the surroundings but also open and receptive to being at peace and accessing our more intuitive faculties.
