What is binaural beats for healing

Binaural beats: more concentration and sleep thanks to sound waves?

Now there is something on your ears! Binaural beats are said to provide more productivity and better memory through their sounds and even help against sleep disorders. We took a closer look and tell you what it is about and what effect the phenomenon is said to have.

What are binaural beats?

That sounds have an impact on us is nothing new. When you're in a bad mood, a favorite song can sometimes work wonders and put you in a better mood or bring back fond memories to life. And that's not a coincidence! Memories are often linked to certain pieces of music. We can remember events or information particularly well when they are linked to positive or negative emotions. And that's exactly the case with music. It is mostly associated with emotions1.

Listening to music while exercising can also have an impact on you and really motivate you! Suddenly you can give even more power during your workout. The same goes for relaxation. Slow beats can help you shift down a gear and leave the stress of everyday life behind you. Your breathing will calm down and your heart rate will slow down.

Our tip: Are you looking for an extra energy boost for your next workout? In addition to good music, a serving of caffeine can provide more power and concentration! Try our Energy Sparkling Water without sugar and without calories, but with plant-based caffeine.

What is binaural

Have you ever heard of binaural beats? The German physicist Heinrich Wilhelm Dove discovered the phenomenon back in 1839. This is a specific one Sensory perception of sound waves with two different frequencies. The word binaural means "with both ears”And in this context refers to that both the left and the right ear perceive the beats separately.

How are binaural beats created?

Binaural beats are created when you use perceive similar frequencies on the left and right that are slightly different from each other. These different frequencies are heard simultaneously, with one Superposition of sound waves in the brain takes place. We perceive noises with our ears, but the actual auditory perception happens in the brain. That means the binaural sounds only present in our inner perception are and are some kind of acoustic illusion.

For example: If you hear a tone of 220 Hertz with your left ear and a frequency of 224 Hertz with your right ear at the same time, you should be able to hear the 4 Hertz difference in the form of binaural beats. So your brain creates sound waves with a frequency of 4 Hertz. By the way: The unit Hertz stands for the number of vibrations of a tone per second.

The American biophysicist Dr. G. Oster did further research in the field and found that binaural beats only perceived can be if they can produced below the frequency of 1,500 Hz become. He also found that the difference between the two frequencies must be less than 30 Hz so that binaural beats experiences are possible for people2.

Binaural beats are great even with one low volume and frequency below 20 Hz perceptible to humans2. For comparison, the human hearing span with normal hearing covers the range from 20 to 20,000 Hertz. The smaller the number, the deeper the tone. So you can experience the binaural beats even at a very low volume that we humans cannot hear.

By the way: headphones for binaural beats are necessary, otherwise you will not be able to experience this. It has to be Stereo headphones act. This allows your ears to perceive the different frequencies separately from the left and right and binaural hearing is guaranteed.

What do binaural beats bring?

Depending on the activity, waves in different frequency ranges also arise in the human brain and can be measured, for example, with the help of an EEG device that is attached to the head. An electroencephalogram then shows the activity of the nerve cells in the form of waves.

The course of these waves depends on whether you are sleeping or awake and whether you are focused or tired. The frequency is high when you are studying in a concentrated manner. Because you are processing a lot of information at that moment. When you sleep or meditate, the frequency of the brain waves decreases accordingly3.

The idea behind the conscious use of binaural beats is that that Affect the brain through them should let. Certain binaural beats frequencies should be able to put the respective person into a state of rest or activity by creating the corresponding frequency difference in the brain.

Your 5 brain frequencies3

Depending on your activity, your brain generates waves in the respective frequency ranges:

Delta waves (0.5 to 3.5 Hz)
These slow waves synchronize deep sleep. This is the state in which you are not dreaming and is important for a good night's sleep. During this time, your body releases hormones that are necessary for your cells to recover and repair.

Theta waves (4 to 7 Hz)
They arise when you fall asleep or when you are very tired.

Alpha waves (8 to 13 Hz)
Here you are in a waking state while your eyes are closed, for example while meditating or daydreaming.

Beta waves (14 to 30 Hz)
These waves show up with open eyes when you perceive sensory stimuli from your environment and are mentally active.

Gamma waves (over 30 Hz)
When you concentrate and study intensely, gamma waves arise. Productivity and creativity can meet here and ensure top mental performance.

Binaural beats are said to have positive effects at the appropriate frequency. So should Binaural Beats promote concentrationby putting a person in the gamma-wave state. You can also do the opposite provide relaxation and prevent sleep disorders help thanks to low frequencies.

Binaural Beats Effect: What Does the Study Situation Say?

The effect of binaural beats is still controversial. Many studies deal with the phenomenon and test to what extent it can help people.

Binaural Beats Concentration and Mood

A study4 tested whether and what effect binaural beats in the beta, theta and delta frequency ranges have on the subjects' mood and performance when solving tasks. 29 participants had to solve tasks for 30 minutes on three different days while they either heard beats in the beta range (16 and 24 Hz) or in the theta / delta range (1.5 and 4 Hz) in the background.

The presentation of binaural beats in the beta frequency range resulted in more correctly solved problems than the one in the theta / delta frequency range. In addition, the study participants reported that they were in a better mood with the beats in the beta frequency range. The results suggest that beta binaural beats provide better performance and mood.

Binaural Beats Sleep

A pilot study5 has investigated whether binaural beats in the delta wave range can lead to better sleep quality and sports performance in soccer players. 15 athletes were exposed to the beats for 8 weeks while they were sleeping. Each time they woke up, they felt questionnaires about how well they slept and how motivated they feel. The control group of 15 sports students did not hear beats but felt the same questionnaires.

After 8 weeks, an improvement in the perceived sleep quality of the soccer players could be observed. An increase in performance in sport was not recorded. To find out, the period of 8 weeks seems too short. There is a need for further research.

Learning binaural beats

Another study6 aimed to investigate the effect of binaural beats on long-term memory. Study participants were blindfolded so that they could only focus on auditory stimuli. After listening to beats from the beta (20 Hz) or theta frequency range (5 Hz) or white noise as a control condition, they had to solve tasks. In doing so, they had to remember things or recognize something.

The beats in the beta frequency range had most of the correct answers. The results suggest that waves in the beta range improve memory and may be used as a tool in learning.

Binaural Beats Depression or Stress

The extent to which binaural beats in the alpha range can provide relaxation and stress reduction was investigated in the following study7 explored. For this purpose, 102 test persons were divided into three groups: (1) audio reinforcement with binaural stimulation, (2) audio reinforcement without binaural stimulation and (3) no acoustic reinforcement.

Before and after a 20-minute stimulation, the physical relaxation reaction of the test subjects was measured in the form of heart rate, breathing rate and selected parameters of the heart rate variability. However, the results did not show any changes.

How dangerous are binaural beats?

Are binaural beats dangerous? To most people, they don't seem to pose a threat. However, binaural beats are not recommended for people suffering from epileptic seizures. In epileptic seizures, the brain waves are particularly high and steep compared to healthy people3. You should also contact your doctor in the case of nerve disorders.

Important: If you have concerns about whether binaural beats are good for you, you should seek advice from a professional or a doctor.
