Brainwave entrainment is a method to stimulate the brain into entering a specific state by using a pulsing sound, light, or electromagnetic field. The pulses elicit the brain’s ‘frequency following’ response, encouraging the brainwaves to align to the frequency of a given beat.

Mental entrainment is a concept that has been around since the mid 1800’s, discovered by a German who was, interestingly enough, considered by many to be the father of meteorology. Mental entrainment, however, has nothing to do with the weather. It has to do with the brain and how binaural beats can affect it. It is a fascinating process and can influence your life in many ways. Here I will try to explain in the simplest terms possible what mental entrainment is and what it does.
First, we must understand a bit about the brain. The brain works by a series of waves or frequencies. For example, when we’re in deep, dreamless sleep, our brain is operating between 1-4 Hz. When we’re anxious or stressed, the brain can operate around 30 Hz. There are, as well, many frequencies in between that control different states of mind.
If we wanted to change our present state, we can use mental entrainment to move our brainwaves to the state we want, such as relaxation.
How does mental entrainment work?
Let’s say you desperately want to relax, but can’t seem to calm yourself down. You would play binaural sounds, which are two tones that are close in pitch (no more than 30 Hz apart), to produce a binaural beat in the brain. One tone could be at 310 Hz with the second tone at 300 Hz. The brain perceives the difference (a binaural beat) which is 10 Hz. Well, 10 Hz is the frequency in which the brain operates when it is totally relaxed. In hearing that 10 Hz binaural beat, the brain will gravitate toward that frequency and you will become calm and relaxed.
Mental entrainment can be used to produce many desired states such as: relaxation, mental focus, higher learning capacity, increased memory and unleashed creativity.
This by no means is an exhaustive explanation, but I do hope it answered some basic questions about this amazing process called mental entrainment. Thanks for reading!
Brainwave entrainment is a method to stimulate the brain into entering a specific state by using a pulsing sound, light, or electromagnetic field. The pulses elicit the brain’s ‘frequency following’ response, encouraging the brainwaves to align to the frequency of a given beat.
This ‘frequency following’ response of brainwave entrainment can be seen in action with those prone to epilepsy. If a strobe flashes at their seizure frequency, the brain will ‘entrain’ to the flashing light, resulting in a seizure.
On the positive side, this same mechanism is commonly used to induce many brainwave states; such as a trance, enhanced focus, relaxation, meditation or sleep induction. The brainwave entrainment effectively pushes the entire brain into a certain state.
Brainwave entrainment works for almost everyone. It is a great way to lead your mind into states that you might usually have difficulty reaching, allowing you to experience what those states feel like.
THE HYPE
There is a lot of marketing hype around brainwave entrainment. It is sold with promises of increasing IQ, promoting weight loss, ‘mind-tripping’, enhancing creativity, concentration, inducing spiritual states and more.
While these claims are not entirely true, they are not altogether false either. In practice, the claims are based on an overly-simplistic view of how the brain and the brainwaves function.
THE RUB
People are very seldom deficient in a certain brainwave type in all areas of their brain. Usually the distribution is much spottier, with an excess in one area and a deficiency in another.
We are all different, especially when it comes to the distribution of our brainwaves. Boosting a certain brainwave state may be beneficial for one person, and emotionally uncomfortable for another. Without knowing each person’s starting position, entrainment can be rather ‘hit and miss’.
If brainwave entrainment leaves you with unwanted side-effects (see below) or discomfort, you’re probably encouraging a range of brainwaves that are already excessive in some area of your brain. The way around this is to get a brain map to see what your brain’s strengths and weaknesses are, and see what (if any) brainwaves could use some encouragement.
