The phenomena of binaural beats and brainwave entrainment can induce the same mental state associated with traditional meditation practice, but quickly.
Our brains have been called “random thought generators.”
Negative thoughts cause chronic stress which, in many real ways, changes the function and structure of your brain. (3)
Chronic stress also causes myriad mental and physical health problems.
An audio technology called binaural beats can help quiet your mind quickly by inducing the kind of brainwave states experienced during meditation.
Binaural Beats As Meditation
One of the most effective ways to control negative thinking is with meditation.
Over 1,000 studies have shown that meditation can make you smarter, happier, and healthier. (6)
Regular meditation can reduce stress, stimulate new brain cell formation, and slow down the rate of brain cell aging.
But anyone who has tried to do meditation the traditional way can tell you that quieting your mind is not easy.
It can take years to master the process.
For those who struggle with focus and concentration, meditation can be frustrating and can become an additional source of stress.
In the past 50 years, technologies have been developed that can induce the same brainwave states as meditation when you simply listen to certain sounds.
One of the most popular forms of sound technology used for this purpose is known as binaural beats.
Using binaural beats technology creates the same brainwave states as meditation, but quickly.
Understanding Binaural Beats: Brainwaves and Entrainment
To fully understand binaural beats, you need to know a few basics about brain waves and a concept called brainwave entrainment.
Your brain cells generate electricity as a way to communicate with each other.
This electrical activity forms patterns known as brain waves.
These patterns can be measured by electroencephalography (EEG), a method of recording electrical activity through the scalp.
Scientists have found five main patterns of brain waves:
Each brainwave state is associated with different states of consciousness.
You normally go in and out of different brainwave states depending on what you are experiencing.
But it’s possible to manipulate your brainwaves by meditating or by using binaural beats or other kinds of sound technology.

Delta Brain Waves (below 4 Hz)
Delta waves are the lowest frequency brain wave and occur during deep, dreamless, restorative sleep.
Sleep is not simply not being awake.
It has its own stages and associated brainwave patterns.
Theta Brain Waves (4 – 7 Hz)
Theta waves are associated with the drowsy state you experience as you are falling asleep, or during light sleep.
They can also be experienced during meditation.

The theta state is characterized by deep relaxation, daydreaming, and creativity.
It is also the brainwave state experienced during hypnosis. (8)
Alpha Brain Waves (8 – 15 Hz)
Your brain enters the alpha brainwave state almost immediately whenever you close your eyes.
Alpha waves are associated with relaxed wakefulness and can occur during light meditation.
Many brainwave meditations seek to induce this state since it’s the alpha state that’s believed to facilitate a bridge between conscious thought and the unconscious mind.
Beta Brain Waves (16 – 31 Hz)
As long as you are physically active and mentally alert, you probably spend most of your waking day in a beta state.

Since the hallmark of the beta state is one of heightened alertness, it can be overdone.
Spending too much time in the beta state contributes to stress and anxiety.
Gamma Brain Waves (32 Hz and above)
Gamma brain waves (not to be confused with gamma rays) are the highest frequency brain waves.
They are the most recently discovered since they could not be measured until the development of digital electroencephalography.
They are also the least understood.
When in the gamma brainwave state, it is thought that the senses are sharpened and that feelings of happiness and peace predominate.
This is the brain wave state you tap into whenever you’re in “the zone” — the state of peak performance and blissful immersion.
Heightened focus, super concentration, and massive productivity are all said to be yours when you’re in the gamma state.
One study found that Buddhist monks can induce a gamma state through meditation. (9)

Brainwave Entrainment: A Natural Phenomenon
The phenomenon of entrainment was discovered by a Dutch scientist over four hundred years ago.
He noticed that his room full of pendulum clocks synchronized automatically.
Even when he intentionally disrupted their rhythms, they would always re-synchronize.
Brainwave entrainment is a high-tech sounding name for a very natural phenomenon.
If you’ve ever been mesmerized by the sound of ocean waves or a crackling fire, you’ve experienced brainwave entrainment.
Entrainment is commonly seen in nature.
Fireflies entrain their flashing lights and frogs entrain their croaking.

Meditation for Anxiety: Proven Way to Calm Your Mind
When you listen to sounds of a certain frequency, your brain waves will synchronize with that frequency.
You entrain every time you hear a musical beat that has you bobbing your head or tapping your foot.
Binaural beats is one of the most popular methods to utilize the phenomenon of brainwave entrainment.
Others include isochronic tones, monaural beats, and audiovisual entrainment.
By listening to MP3s or CDs that produce brainwave entrainment, you can induce a desired brainwave pattern quickly and reliably.

How Binaural Beats Work
Humans can generally hear sound frequencies in the range of 20 Hz to 20,000 Hz. (10)
This means that our brainwave frequencies mostly fall below our audible range.
So how can we get our brains to entrain to sounds we can’t hear?
The binaural beats phenomenon is the key. (Binaural means “two ears.”)
When two tones that are slightly dissimilar in frequency are processed by the brain, it registers a beat at the difference of the frequencies.
The diagram below illustrates how this works in practice.
If you listen to a 124 Hz sound in your left ear, and a 114 Hz sound in the right, your brain entrains to the difference — in this case to 10 Hz, which is in the alpha brainwave frequency range.
Since each ear has to perceive a different frequency for binaural beats to be created, binaural beats are best experienced when the two tones are heard through stereo headphones.
Listening to these sounds triggers numerous beneficial mechanisms.
It changes your biochemistry by modulating the production of hormones and neurotransmitters.
Listening to binaural beats can reduce levels of the stress hormone cortisol by as much as 80% and increase the sleep hormone melatonin by nearly 100%! (13)
Other biochemicals shown to be affected by binaural beats include DHEA, melatonin, serotonin, dopamine, epinephrine, and norepinephrine. (14)
The Advantage of Binaural Beats Meditation Over Traditional Meditation
Mindvalley, one of the world’s largest personal development publishers, surveyed their customers to understand “why people don’t meditate.”
Their customers were certainly aware of the benefits of meditation — that meditation can tame negative mental chatter to decrease stress and improve performance, mental well-being, and overall health.
So what obstacles stood in their way?
According to the 400,000+ people who responded, the main reasons people don’t stick with a meditation practice are:
- They can’t tame their mental chatter.
- They can’t focus.
- They feel physically restless.
- It takes too long to get the desired results.
Do any of these reasons sound like anything you’ve experienced?
Yeah, we’ve felt that way too.
Using binaural beats provides an easy shortcut to a meditative state.
All you have to do is put on a set of headphones or earbuds, relax, and listen.
This can bring your brain into a similar state as deep meditation quickly.
Evidence-Based Benefits of Binaural Beats
The study of how to manipulate brain waves for the enhancement of brain health and mental well-being is in its infancy.
So far one study, A Comprehensive Review of the Psychological Effects of Brainwave Entrainment, is often cited as the gold standard on the effectiveness of brainwave sound technology.

The Power of Self-Hypnosis to Improve Your Mind
This meta-analysis of peer-reviewed studies found brainwave entrainment technologies, including binaural beats, to be beneficial for the following:
- attention deficit
- behavioral disorders
- cognitive decline
- learning disabilities
- learning disorders
- mental disorders
- premenstrual syndrome
- verbal learning
Impressively, just one session of brainwave entrainment meditation was found to be helpful for some conditions including memory, attention, stress, pain, headaches, and migraines.
This study concluded that:
“People suffering from cognitive functioning deficits, stress, pain, headache/migraines, PMS, and behavioral problems benefited from BWE. However, more controlled trials are needed to test additional protocols with outcomes.”
You can read or download a copy of the study here.
More recent studies have confirmed binaural beats to be helpful for memory, creativity, attention, anxiety, depression, pain, sleep, tinnitus, post-traumatic stress, cognitive functions, and emotional state. (15, 16, 17, 18, 19, 20)

This sound is not very pleasant which is why most binaural beats meditation sound files are overlaid with music or environmental sounds.
Some binaural beats programs seek to bring about a particular state associated with meditation — usually alpha or theta, or sometimes the gamma state.
Others are designed to help alleviate specific problems or achieve specific goals.
There are binaural beats audio programs designed to induce sleep, reduce anxiety, and increase weight loss, concentration, or study skills.
One of the most unusual uses of binaural beats technology is to encourage lucid dreaming, a state of consciousness in which dreamers are aware that they are dreaming, to achieve various cognitive and emotional benefits.

Binaural Beats Warnings
Some websites that sell binaural beats meditations claim they “can’t” be dangerous because they produce brainwave states that naturally occur.
But this is faulty logic since your body can turn on many responses or create chemicals that, in excess, can do you harm.
And while binaural beats are generally considered safe for most people, there are a few exceptions.
There is some concern that listening to binaural beats could be a problem for anyone who has epilepsy, an irregular heartbeat, or wears a pacemaker.
Since brain waves and heart rhythms are both electrical patterns, it is theoretically possible that listening to binaural beats could trigger seizures or disrupt heartbeat rhythm in susceptible people.
Pregnant women and children should avoid binaural beats applications since their safety has not been determined for these groups.
If you have a serious mental disorder or brain injury, discuss with your doctor before giving binaural beats a try.
If you experience any negative effects while listening to a binaural beats meditation, such as headache, nausea, dizziness, or increased heartbeat, stop using it immediately and stick with traditional meditation.
Binaural Beats and Meditation: Take the Next Step
Meditation is one of the best things you can do for your health and mental well-being.
