![]() REM sleep itself is mostly composed of beta wave and other activity that’s similar to an alert, waking brain.ĭeep meditation produces theta waves, which are slower and lower frequency (between 5-8 hertz) than Alpha waves. Theta: This brainwave pattern is associated with deep relaxation and with some stages of sleep, including the lighter stages of non-REM (NREM) sleep. Alpha waves are associated with states of meditation (your yoga class probably puts you in an alpha state), and also with our ability to be creative. ![]() Slower and lower in frequency (between 9-14 hertz), alpha waves are dominant when we’re calm and relaxed, but still alert. At the higher levels of this range, beta waves are associated with anxiety.Īlpha: Alpha brainwave patterns are associated with a state of wakeful relaxation. Beta waves are fast, with a higher frequency (between 15-40 hertz). When you’re analyzing an issue at work, you’re probably in a beta-dominant state. When beta brainwave patterns dominate, we’re primed to focus and concentrate, to make decisions and think analytically. When a person’s brainwaves are at 6 Hz, then the person can experience a lot of calm and feel a deep sense of relaxation.īeta: These brainwaves are associated with high levels of alertness and arousal. This is the binaural beat it is the frequency that your brain will follow along to. So if a frequency of 200 Hz was sent to your left ear and 205 Hz to your right ear, there’s a difference of 5 Hz between your ears. If not, then the two tones will be heard separately in your ears and the brain won’t perceive any beat. For the ‘music beats’ to be noticed though, the tone frequencies need to be below 1,000 Hz.Īlso, the difference between the two different frequencies must also be less than 30 Hz, or equal, for this effect to occur. Your brain picks up the difference in the tones, and then ‘trains’ itself to ‘hear’ the difference between the frequencies to which it is listening.Īnd this process is called ‘frequency following response’. The difference in the frequency between the two tones being heard is what is called binaural beats. When you hear the two tones together through your left and right ear, your brain listens and perceives these tones as ‘music beats’, audible to your ears. That means that each tone will be at a slightly different frequency as you listen through your headphones. That’s what the word binaural means - “having two ears.” Each of your ears will receive a slightly different frequency, all at the same time. If you know binaural beat therapy, you know that two separate tones are heard in your ears. So it was figured that if we introduce an external rhythm that vibrates our body or our auditory system, we will also experience the entrainment the clocks did – it’s called brainwave entrainment. Humans, like those clocks, also have rhythms present in our own bodies, present in our hearts, and our brains. He realized that the vibrations on the shared wall were what “communicated” the two clocks, that they re-entrained themselves back on the same wall, back to the same pattern of movement and speed of the other clock. If he moved one of the clocks to another wall, there was no synchronization. He noticed the synchronization of the pendulums regarding their speed and angles. In the 1600s, Christian Huygens, a Dutch scientist noticed two clocks with pendulums hanging together. These melodic sounds make us conscious of the relationship, the connection between the body and mind. We all love nature and the sounds it makes the sound of thunder, ocean waves pounding on the beach, the gentle flow of a river – what about a symphony concert? ![]() You can get frequencies which go even beyond these measurements, but they are out of human audibility range. ![]() As humans, our hearing capacity is measured in hertz too, so low noises we will hear at around 20 Hz, or we can hear up to very high frequencies, such as 20,000 Hz. Frequencies are measured in Hertz (Hz) and each cycle is measured in Hertz. It is the number of times sound waves cycle between the negative and positive brainwaves or vibrations, per second. It is because the science behind binaural beats is frequency – we will look at how you can benefit from the technology of binaural beats how your brain responds to the frequencies and certain combinations. Most people have heard the word, ‘frequency’ when it comes to music, so maybe this is a good place to start when it comes to binaural beats. ![]() But actually, understanding what it is and how it can be of benefit to you is a little bit harder for many people to understand. When people talk about binaural beats, it might sound high-tech and complicated, but bottom line is, it’s placing some headphones over your ears, sitting back and pushing the ‘play’ button on, from whichever device suits you best. Using binaural beats technology is really easy. ![]()
