I came across binaural beats some 25 years ago whilst doing some research on how to induce a state of meditation quickly and effectively.
During my search I stumbled across the Robert Monroe Institute website for Hemi-Sync (Brain Hemisphere Synchronisation) (www.monroeinstitute.org) which detailed case studies where combined wave lengths were used to achieve certain states of mind. Needless to say there were numerous but from that moment on, I was hooked.
Today I use music laced with binaural beats in conjunction with my Reiki-Meditation work and it has proved very effective in inducing meditative, trance-like states.
Below is a brief description of how binaural beats work and potential benefits.
Sound has a profound ability to alter your brainwave state particularly when it has a rhythm to it.
Our ancestors knew this instinctively. African tribes would use special drumming techniques to take the members of their ritual into a deep hypnotic trance. Medicine men would use these rituals to invoke deep visions, aid recovery from sickness, injuries and even communicate with the spirits.
With modern audio technology called binaural beats, you can mimic this same technique digitally through a special, trance-inducing technique known as brainwave entrainment.
The binaural auditory beat that a person hears is the difference in frequency between the left and the right ear and should be at frequencies lower than 1000 Hertz (Hz), for the brain to detect the binaural beat.
For example, if the left ear registers a tone at 200 Hz and the right at 210 Hz, the binaural beat heard is the difference between the two frequencies — 10 Hz.
When you play two separate frequencies in each ear, say 140 Hz and 149 Hz, the difference in frequency is 9 Hz. Your brain compensates for this difference and a third tone of 9 Hz is experienced. This will result in your brain being lowered or raised and tuned into the desired frequency. This is how binaural beats are produced.
Effects on brainwaves:
Gamma Waves (40Hz+) are the apex of human brainwave frequencies of 24hz and higher. They have been associated with peak concentration, and your brain’s optimal cognitive functioning.
Beta Waves (13-40Hz) are associated with normal waking consciousness. When you are focused on activities that require a lot of thinking, such as working, doing calculations, or reading complex non-fiction books, for prolonged lengths of time, you can start to feel stressed out.
Alpha Waves (7-13hz) are associated with light meditation, peak performance, creativity and relaxed alertness. Your brain goes into this state naturally when you are daydreaming. Alpha waves also become more predominant when you close your eyes and relax your mind. This is the perfect state to be in for subliminal mind programming and enhancing your creativity.
Theta Waves (4-7Hz) are associated with deep meditation. They occur during heightened states of creativity and inspiration as you begin to process unconscious material.
Delta Waves (<4Hz) are associated with a deep sleep state or unconsciousness. Experts of deep meditation can consciously move into this state of mind and access the higher brain centre. After much practice, out of body experiences and astral projection are possible during these meditative states.
Through the use of the right brainwave entrainment therapy protocols you can train your brain to be able to consciously flow more easily into desired brainwave states at will, without becoming dependent on the technology to experience the effects.
