In my early twenties I was a bad sleeper and with the help of a binaural beat cd, I learned how to sleep deeper during the night. In my own experience, binaural beats did produce an effect. Note the small amplitude (the difference between the highest peaks and the lowest peaks)! “Binaural beats cannot generate entrainment because, as two steady tones, they do NOT impact the thalamus.” He also cites studies that clearly show the little entrainment binaural beats provide to the brain. His conclusion: “If, in theory binaural beats do not produce entrainment, do they produce entrainment and drive brainwaves in reality? The simple answer is NO!” To compare: isochronic tones and monaural beats have a 50 db difference between loud and quiet. … This means that binaural beats are unlikely to produce any significant entrainment because they don’t activate the thalamus.” “Binaural beats are not very noticeable because the modulation depth (the difference between loud and quiet) is 3 db, a two-to-one ratio. This article by Dave Siever from (a producer of “Audio-Visual Entrainment machines”) claims that binaural beats don’t work as well as people seem to think:
This picture explains: 510 hz in one ear, and 500 hz in the other: your brain perceives the difference between these two frequencies: 10 hzīut how effective are binaural beats really? The effect of a third frequency is produced within your brain itself. There are a lot of binaural beat cd’s and tracks being sold on the internet (and sometimes at a high price!).īinaural beats are created by presenting two different tones at slightly different pitches (or frequencies) separately into each ear. The tendency of the brain to “fall in step” with a presented stimulus is called “entrainment”. And binaural beats are by far the most popular way to “entrain” the brain. The brainwaves and their accompanying states: Every frequency has its own characteristic 7 Conclusion: throw away all your binaural beats tracks?Įach frequency comes with its own “brain state”įor example: if you stimulate your brain with “alpha waves” (frequencies between 8 and 12 hz), the result would be that you feel more relaxed and less anxious/stressed.Īnd if you present your brain with frequencies in the “theta” range, you might experience drowsiness and sleepiness.6 So why do many people still insist on using binaural beats?.5 Binaural beats don’t work as well as these alternatives.4 Maybe a slight entrainment effect from binaural beats?.3 But how effective are binaural beats really?.2 Brainwave entrainment by binaural beats.1 Each frequency comes with its own “brain state”.It’s worth noting that I do listen to binaural beats while doing my evening routine with MoveWell to wind down before sleep. There needs to be more experimentation with all of this stuff. That said, if it works for you – let me know.

So, it could potentially work if you’re planning on falling asleep immediately (and using the beats to jump-start your lucid dreaming), but if you need longer to fall asleep, you might find binaural beats unhelpful & might want to stick to your white noise generator instead. While the beats might help you be more creative, they may not help the sleep part of the equation. If you’re looking to combine binaural beats with lucid dreaming, you may be disappointed. You can dig into the nitty gritty of the science & studies at the links & content below. These beats have long been used in meditation, sleep and relaxation. That said, it’s pretty consistent across the board that studies show increased levels of productivity in creative tasks (although they do have different effects on different people – so your mileage may vary). Great question – it’s a new area of work, so there’s only a few studies on it (and needs to be a lot more). This tone is the “beat” and various “binaural beat tracks” are designed to help you tackle certain tasks more effectively (work, healing, mood, etc). Because of the difference in frequencies, the brain perceives a third tone. How Do Binaural Beats Work?īinaural means “to hear with two ears.” What happens is a “brain illusion.” Two different tones are transmitted to each ear at different frequencies. They’re frequently considered to be useful in creative projects, improving productivity, as well as meditation and therapy. Binaural beats are a sound wave that creates the illusion in your brain of a “beat” due to the frequencies they’re transmitted at.
