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.Beta (13 – 40 Hz) – Active, alert and focused.Your brain enters into several different states during the day with each of these states generating its own unique frequency. They’re cheap, effective and all you need to is relax and listen to them through stereo headphones. ![]() There’s a range of binaural beats for sleep available to purchase. The method of inducing a brainwave frequency is called brainwave entrainment. It’s a powerful technology that I’ve been using myself for years with very good results.īinaural beats aren’t the only way to produce brainwave entrainment but they’re probably the most popular. So by inducing a new lower frequency with binaural beats, your brain begins to lower its own frequency to match this new frequency. Scientists discovered that the brain synchronises itself to a dominant frequency. Your brain stays alert, preventing you from relaxing.īy using binaural beats, you can quickly induce the frequencies associated with sleep in your brain within minutes. This can be hard, especially after a busy day. To sleep, your brainwave frequency needs drop to a slow delta. So if you’re feeling alert and focused, your brainwaves are in the beta frequency If you’re feeling relaxed, they’re in the alpha state. Your alertness is linked to the dominant frequency of your brainwaves. ![]() Sounds like something straight out of a science fiction novel, but binaural beats are a very real and very effective way to help you sleep. ![]() Binaural beats is a scientific method that helps you go from alert to relaxed to asleep within minutes by using a process to alter your brainwaves.
