Binaural Beats Therapy: What is it and How It Affects Your Brain?

“Binaural Beats Therapy” or “Digital Drugs” whatever you say, is supposed to help you to cure several mental illnesses, including disorders like anxiety, stress, depression, and sleep.

But do you know how it works & what are the benefits of binaural beats?

Let’s understand more about it.

What Are Binaural Beats?

Heinrich Wilhelm Dove (Prussian meteorologist ) discovered the perceptual phenomenon of “binaural beats” in 1839, and it was first discussed in the scientific literature in 1973 by Gerald Oster’s article “Auditory Beats in the Brain”.

When you hear two beats in each ear, each with a slight variation in frequency at that time, your brain generates a new beat, i.e. a tone that produces from the difference in frequencies. And this new tone is called a binaural beat.

Let’s understand with an example.

Suppose you are listening to a tone with 100 Hz (in your right ear) & another tone with 110 Hz (in your left ear).

The binaural beat at a time is 10 Hz, which is considered an auditory illusion. So, instead of listening to Two unique tones, you heard a new tone at 10 Hz.

Note: Binaural Beats only work when the frequencies between two tones are less than 1000 Hz. And the gap between the two tones is not over 30/35 Hz.

Binaural Beats

These third beat / binaural beats provide us with relaxation and activeness. Research stated that these binaural beats are used for 2 purposes:

1) As a kind of therapy or medicine, and

2) As an alternative option to psychoactive drugs that affect your nervous system, mood, cognition, or behavior.

How Does Binaural Beats Therapy Affect To Your Brain?

Studies on binaural beats have revealed benefits for memory, anxiety reduction, and pain relief.

Using binaural beats can be integrated into a variety of other widely practiced digital sound-based therapies, including ASMR (Autonomous Sensory Meridian Response). Recent studies suggest that ASMR may have therapeutic advantages for mental health, which emphasizes the broader potential of digital sounds.

The main unit of measurement for Binaural Beats is Hertz.

1 Hertz = 60 vibrations per minute

The brain’s capability increases with increasing Hz. Also, at lower Hertz frequencies, the brain is less active.

The difference in the frequencies can ‌produce binaural beats. Various degrees of brain wave activity are correlated with different results for each frequency.

When binaural beats are exposed to your brain at a new frequency, your brain waves are driven to synchronize with it by putting you in a new “brain state.”

There are 5 different ‌brain waves. Generally, low-frequency waves are linked with “Delta” & “Theta” waves. These waves boost your relaxation and sleep ability.

While high frequencies are related to “Gamma” waves. It could increase your level of alertness, concentration, or memory.

The ability to pay attention has been connected to midrange frequencies. When you focus inside (like in meditation), your brain enters an “Alpha” state, and when you are tuned in to your environment, your brain will enter into a “Beta” state.

Connection Between the Brain and Binaural Beats Therapy

Your brain activity matches the frequency established by the beat’s frequency when you listen to binaural beats. It is known as the frequency-following effect.

This means that you can teach your mind to achieve a particular condition of consciousness via binaural beats.

The superior olivary complex is the first part of the brain to handle sound information from both ears when you listen to binaural beats. It synchronizes a range of neuronal processes across the brain.

This complex responds when it detects two overlapping frequencies by producing a binaural beat that changes the brain waves. This synchronization of neural activities across the brain is known as entrainment.

Entrainment is a common part of brain function. Some academics claim that specific binaural beats can strengthen particular brain waves when you listen to them. As a result, several brain processes regulate thought and emotion that can be sped up or repressed.

Benefits Of Binaural Beats Therapy

According to the preliminary study, binaural beats may improve your sleep quality. Binaural beats with a delta frequency of 3 Hz were used in a study to illustrate how they can cause the brain to go into delta activity.

Soccer players who listened to binaural beats with frequencies between 2 and 8 Hz reported better sleep quality, less tiredness, and easier waking up. Binaural beats can aid in lowering anxiety, which ‌promotes better sleep.

These researches have been conducted on a portion of people. Hence, we recommend you always consult a physician before utilizing binaural beats.

Benefits Of Binaural Beats Therapy

1) Reduces Anxiety

A journal published on 15 people showed that those who listened to binaural beats in the theta range (4 – 8 Hz) for 30 minutes had reduced symptoms of mild anxiety.

Several studies have shown a link between binaural beats and decreased preoperative anxiety in surgery patients. Here are the 10 Mindfulness Exercises For Anxiety Relief

2) Helps in Meditation

In a study, participants who listened to 30 minutes of theta (6 Hz) binaural beats had an easier time entering a deep meditative state.

Meditation can reduce stress, anxiety, and other diseases. And details given by Nantawachara Jirakittayakorn and Yodchanan Wongsawat’s novel suggested that ‌it can also lower blood pressure, inflammation, and perception of pain.

Thus, binaural beats could be a helpful tool for people who want to meditate for improving their health.

3) Increases Concentration

The evidence of the global-local task with 36 participants found that individuals who listened to gamma (40 Hz) binaural beats for just 3 minutes improved attention to certain visual elements.

Another study on Binaural auditory beats claimed that those who spent 30 minutes listening to beta (16–24 Hz) binaural beats had increased concentration easily.

4) Enhances Mood And Emotional State

A pilot study conducted on Binaural beat technology in human health by Helané Wahbeh, Carlo Calabrese, and Heather Zwickey claimed that those who listened to theta (7 Hz) binaural beats for 30 minutes had decreased anxiety, unhappiness, and tiredness.

Another analysis of a 30-minute visual vigilance task (a task for sustained attention, & mood) was performed on 29 participants by J D Lane, S J Kasian, J E Owens, and G R Marsh.

They used simple tones or binaural beats in the beta range (16 and 24 Hz) or theta/delta range (1.5 and 4 Hz).

As a result, the participants improved their feeling, became more cheerful, and saw a decrease in their depression symptoms.

5) Recalling Memory

Some interesting research suggests that binaural beats can improve many forms of memory. By listening to alpha binaural beats, you can enhance your memory to recall old things.

Beta (20 Hz) binaural beats help you improve long-term memory, while theta binaural beats (5 Hz) improve short-term verbal memory.

6) Reduces Pain

According to the National Institutes of Health, chronic pain affected 10% to 50% of the adult population in the United States in 2011, costing US companies $61 billion each year.

To measure the effectiveness of theta binaural beats for treating chronic pain, Donna de Zampi experimented with 28 participants.

For 20 minutes, participants listened to two recordings for 14 days. One with TBB (theta binaural beats) at 6 Hz and the other with a non-binaural beat tone at 300 Hz.

Consequently, the analysis showed that the group with binaural beats had a significant effect in reducing subjective pain intensity over the non-binaural interventions.

7) Get Quality Sleep

The impact of sleep deprivation on psychophysical performance and well-being is studied in depth and shows how you can improve the quality of your sleep!!!

So, it claimed that binaural beats around 2-8 Hz are the best option for getting deep sleep.

8) Cognitive Flexibility

According to a study by Leiden University, The Multitask ability (Cognitive Flexibility) of 40 students (32 female, and 8 male) showed improvement in just 3 minutes by listening to gamma binaural beats (40 Hz).

9) Creativity

Many cognitive processes, some of which are affected by the neurotransmitter dopamine, are necessary for human creativity.

This shows that therapies that either directly control dopamine production or transmission, or impact dopamine-driven systems, may boost creativity.

An experiment on 24 participants showed that those who listened to either alpha (10 Hz) or gamma (40 Hz) binaural beats for just three minutes had enhanced indicators of divergent thinking. It is a component of creativity related to the capacity to devise various solutions to a problem.

Research Supporting To Binaural Beats Therapy

In the past 25 years, many studies have been done on the benefits of Binaural Beats therapy.

These studies show how binaural beats affect your brain and help in reducing anxiety, & stress and increasing your mood.

Let’s have a look at the list of a few studies done in this context.

  • In 2005, a controlled study done on 100 people shows that you can reduce half of the percentage of the Anxiety effect by listening to Binaural Beats audio.


  • An Uncontrolled pilot study was conducted in 2007 for 60 days on the participants by instructing them to listen to a CD containing delta (0-4 Hz) binaural beat frequencies.

According to the research, regular listening to binaural beats reduced stress and anxiety and increased awareness, concentration, motivation, confidence, and meditation.

  • In 2011, a trial study was conducted on 291 patients who were admitted to the emergency department at a hospital. With the use of binaural beats, anxious ED patients saw a decrease in anxiety by 10-15% levels.


  • Sleep is necessary for maintaining physical and cognitive processes for all of us. The benefits of binaural beats and autonomous sensory meridian response (ASMR) were integrated into a 2019 study. It showed that the 6 Hz binaural beat of the theta band (4-8 Hz) gave a non-rapid eye movement (NREM) in sleep stage 1.
