Having studied patients over the years, they also knew what frequencies corresponded to each specific brain state. Numerous studies have shown that in addition to deriving the binaural beat frequency, the brain will begin to follow or match its activity to that frequency, a phenomenon known as "brainwave entrainment."ĭecades ago, scientists identified the fact that the brain operates at different frequencies depending upon its current state. In addition to the two tones, you should hear the binaural beats as sound pulses with a rate of around 4 times per second. In 1839, physicist Heinrich Wilhelm Dove discovered that when an audio tone at one frequency is presented to the right ear, and a slightly different frequency tone is presented to the left ear, the human brain "resolves" the small difference by perceiving a third frequency, now known as the "binaural beat frequency," which is simply the difference between the two.įor example, if your right ear is presented with a tone at a frequency of 200hz while your left ear is presented with a tone at 206hz, your brain perceives both of the original tones, along with a third, low-frequency tone at 6hz, which is the difference in frequency between the two.Ĭlick on the above audio to hear binaural beats - listen through headphones or ear-buds. So read on to discover how binaural beats for sleep can help you attain blissful slumber. Finally, we'll wrap up by telling you how you can use the simple principle of brainwave entrainment along with specially targeted binaural beats to create a perfect environment for sleep - using our totally Free Fuzing App. We'll cover each of the brainwave states with a detailed explanation of what defines each state. We begin with an explanation of what binaural beats are, along with some interesting properties that can be used to tell our brains to slow down in preparation for sleep. This article explores how you can use binaural beats for sleep to help you get a restful and rejuvenating night's sleep, without the need for drugs or expensive gadgets.
