The first recorded clinical application was by a French psychologist, who again used a spinning wheel but this time illuminated with a lantern instead of the sun. A Brief Historyīrainwave Entrainment has been used possibly as far back as 200AD, where Ptolemy of the Ancient Greeks noted the effect of flicking sunlight created by a spinning wheel. Published studies have shown the huge effect binaural beats have on influencing our state of consciousness. Scientific Research on Binaural Beatsīrainwave Entrainment as we know it today is a product of modern science. So while a 10 Hz tone couldn’t be directly heard, using binaural beats we can create that tone inside our brain. So if we had a tone of 500 Hz in one ear and a 510 Hz tone in the other, the result would be a 10 Hz tone. These frequencies when processed by the brain cancel each other out, creating a whole new frequency. Binaural beats offers a novel way of producing these lower tones not through our ears, but directly inside our brain.īinaural beats is a method where two sound waves of different frequencies are introduced into each ear. However we humans generally can’t hear anything below 20Hz, so listening to a normal 20Hz tone would be useless. By introducing these new lower frequencies, your mind begins to lower its own brainwaves to match this new frequency. So if you want to sleep, you would listen to audio that begins at your current frequency and slowly descends to a delta frequency. Sleep experts recommend a wind down period of at least half an hour before you go to bed for this very reason, to allow your mind’s frequency to begin its decent.Įssentially, the faster we can get to theta and delta, the faster and easier it will be to relax and fall asleep.īrainwave entrainment is a method to alter the frequency of your brainwaves by listening to audible tones containing the desired frequency. So to get to sleep, you need to go all way down to theta, touching delta. Theta (4 – 8 Hz) – drowsy, light sleep and dreams.Alpha (8 -12 Hz) – Relaxed, calm and creative.
