Binaural beats have been long used in psychoacoustics, although the claims and studies relating their cognitive effects are more recent. A great deal of confusion subsides regarding their latter use. As Garcia-Argibay et al. concluded, there are several mediating variables, such as beat frequency, exposure time or stimulus masking, that are not always clearly reported. Furthermore, we conclude that there are two important factors that are usually considered as trivial: proper EEG analysis and the use of a proper control condition. Future binaural beats studies should be mindful of these variables and report them accordingly. Several studies that did not find any entrainment to the beat frequency of binaural beats did not use standard normalization practices . The human EEG spectrum exhibits a 1/f power scaling . By properly normalizing data using a baseline condition, we ensure that all data will have the same scale, and we are appropriately disentangling background and task-unrelated dynamics . Researchers should be mindful of the analysis approach they are taking, as well as using an appropriate control condition to truly elucidate whether binaural beats are a special kind of stimulus or their advantages are due to stimulus properties .

What Are Binaural Beats

The perceptual phenomenon of binaural beats was discovered by Heinrich Wilhelm Dove in 1841 and first described in scientific literature in 1973.

The perceptual auditory illusion created by binaural beats occurs when two pure tones of slightly different frequencies are presented to each ear. These two tones are then processed within our brains to sound like a third frequency. This third frequency is thought to produce a range of effects, including relaxation and attentiveness.

Academic research has focused on two main uses for binaural beats:

1) as a medical treatment or therapy

2) as a substitute for or complement to psychoactive drug use .

The Benefits Of Binaural Beats

Now that weâve covered the different types of frequencies and their benefits, here are some more benefits linked with adjusting these frequencies to create binaural beats:

  • May reduce anxiety

The results of a pilot study on the effects of binaural beats suggest that binaural beat technology may have positive outcomes in decreasing trait anxiety and have an effect in increasing quality of life.

  • Binaural beats may enhance creativity and cognitive function

Suffering from a creative block? Try tuning in to a 10 Hz frequency. Although not a cure-all for the occasional creative block or two, binaural beats can help stimulate the brain, especially the parts responsible for creativity. Want to throw in improved memory in the bag? Listening to 5 Hz for 15 minutes may help with your short-term memory, while listening to 20 Hz for 12 minutes may help improve your long-term memory.

  • Better meditation

Itâs all about slowing down and quieting the mind when it comes to meditation. Want to experience deep, meditative sleep? You might want to listen to theta beats. Perhaps youâd like to have better concentration? Try listening to a 14 Hz frequency for 12 minutes.

  • Binaural beats may foster a better emotional state

Want to be in a better mood? Binaural beats may be able to help you with that. Aside from the benefit of having a meditative state of mind, these beats may also offer stress relief, paving the way for positive moods.

Heal Damaged Brain Cells

I gave binaural beats a try for a week in an attempt to calm my dreams, relax my teeth-grinding tendencies, improve sleep quality and provide a much-needed afternoon energy boost. I didn’t notice any dramatic changes in the short term, but apparently that’s not unusual.

“The theory is that it should happen immediately. But in reality I think the brain needs to get accustomed to it, so I think 1-3 days would be my personal recommendation,” explains Breus. Since I tend to be pretty stubborn on all fronts, I plan to keep up the effort to see if my results show up over time.

Elizabeth Davidson, of Moline, Illinois, turns to binaural beats almost every day, and is just one among legions of people who swear by their effects. “Most of the time when I am at work, I use a concentration-focused binaural beat that really helps me focus more than any other tool,” she emails, noting that she prefers to get her beats from the app Binaural Chakra Therapy.

Of course, this emerging field has yet to be conclusively proven one way or the other. Some studies claim that binaural beats are effective at anxiety reduction, which is certainly good news for people dealing with this mental illness. However, other therapy and/or treatment methods should not be discontinued. “In addition there is some evidence that they could change hormonal production,” Breus notes.

How To Use Binaural Beats

To listen to binaural beats, a person will need a pair of stereo headphones and an MP3 player or another music system.

As the leading authorities in psychiatric treatment have no recommendations for binaural beats, it is usually the producer of the tape that makes the suggestions for use.

People should follow the instructions carefully. Those who do not see any reduction in anxiety might benefit from trying a different producer, type of sound, or frequency.

It is important to avoid using binaural beats therapy while undertaking tasks that require alertness and full attention, such as driving.

suggested that binaural beat therapy may yield some benefit for people with mild anxiety. However, the authors stated that it warranted further study only as a therapeutic measure to support conventional treatments for anxiety.

Despite this, other researchers have continued to investigate this therapy. A 2005 study involving more than 100 participants who were due to receive general anesthesia for a day procedure reported a decrease in preoperative anxiety after exposure to a delta wave binaural beat.

The participants in this study listened to 30 minutes of binaural beats before surgery. However, the researchers noted that people experiencing high levels of preoperative anxiety could listen to binaural beats for up to 1 hour before anesthesia to reduce levels of anxiety.

Although there is

Binaural Beats Elicit Cross

Binaural conditions elicit a front to back, cross-frequency connectivity pattern at beat frequency while binaural elicits a widespread connectivity pattern at frequency. In line with our results, several groups have found binaural beats eliciting activity outside of the frequency range of the beat. Despite this, these findings do not seem to be consistent: using binaural beats, Gao et al. found a decrease in relative power over left temporal areas and Ioannou et al. report no significant difference from binaural beats at other frequency bands.

The Brain Unleashed With Binaural Beats

Did you know that geniuses like Albert Einstein, Mary Shelley, and Salvador Dali attributed their work to the highly creative mind states they accessed?

Imagine being able to write when your mind feels blocked. Or being able to lift your mood when youre feeling down. Or sleeping soundly the night before an early morning business flight.

If a technology that allowed you to accomplish these activities quickly and safely existed, would you try it? Well, such technology exists, and its called binaural beats.

How binaural beats work

When two slightly different frequencies of sound are played into each ear, the brain perceives a fixed beat or frequency. These beats are referred to as binaural beats.

The frequency of sound perceived by the brain is the difference between the two frequencies being played in each ear. For example, a 10 Hz binaural beat is created by playing the frequencies of 210 Hz and 200 Hz in different ears.

The benefits of binaural beats come when the brain responds with synchronized neural activity and changes the brain waves. Certain cognitive functions like sleep can be enhanced or suppressed while listening to certain frequencies.

Sometimes, you need a little peace and quiet to stay sane. But it turns out too much quiet can drive you crazy– or at least make you hallucinate. That’s what scientists at Orfield Labs in Minneapolis have found by studying how subjects react in their anechoic chamber, also known as the world’s quietest room.

Who Should Not Use Binaural Beats

If you have epilepsy or heart issues, however, talk to you doctor before trying any sort of Binaural Beat therapy. Due to the nature of the beats, you could irritate an existing problem.

Purported Benefits Of Binaural Beat Therapy

Binaural beats are supposed to generate the same relaxing effects of meditation because they produce the same brain waves observed in a meditative state. As a result, binaural beat therapy may have many of the advantages of mindfulness techniques, such as:

  • Relieving stress: Binaural beats are said to help the body and mind relax, thereby relieving stress and anxiety. Binaural beats have been reported to promote a general sense of mental well-being as well as reduce depression and general mood disorders.
  • Reducing anxiety: When used regularly, binaural beats are thought to be able to reduce generalized anxiety in the long run, as well as anxiety associated with specific situations. Binaural beats have been shown in studies to reduce anxiety by 26.3%.
  • Helping with sleep: Certain frequencies of binaural beats activate certain brain waves, which can help the body and mind relax and sleep more deeply.
  • Increasing focus: Binaural beats have been studied for the treatment of attention deficit hyperactivity disorder , a condition that causes people to struggle to maintain focus on one task, among other symptoms. While more research is required, some potentially promising results have been demonstrated.
  • Improving memory: According to some research, people who listened to various frequencies of binaural beats had better memory outcomes.

    What Are Binaural Beats and How They Affect Your Brain

    Now youve set everything up, you can use your desired lucid dreaming technique, such as the WILD or DILD.

    Binaural beats are very versatile and can be used when you go to bed at night or when youre waking up early during your REM phase of sleep.

    For example, if you like using the WILD technique, you can start listening to them after your early alarm wakes you up.

    Both Beat Types Elicit Differential Short

    Monaural and binaural beats affect short range electrode level connectivity patterns differentially. We only found a significant short-range effect in monaural and binaural conditions, which suggests that both beat type and frequency are non-trivial parameters of stimulation. Furthermore, due to both binaural and monaural beats producing such short-range effect, we can rule out conclusions such as this activity being a by-product of sustained listening or binaural integration. Our findings are in accordance with those from Becher et al. . Using both intracranial and scalp EEG, they found peak EEG power at 40Hz at the scalp electrodes using the power of the envelope of the signal . They found a similar effect in temporo-lateral intracranial electrodes, suggesting this entrainment originates in auditory cortices. Furthermore, they found a significant decrease in EEG power at 5Hz in temporo-basal anterior and posterior areas, which might explain the local activity in our participants. This activity could be in line with a dipole from auditory cortices pointing upwards, which suggests there is only one active cortical source. On the other hand, binaural conditions elicited a positive parietal cluster at 40Hz . The functional meaning of these short-range patterns remains unclear as we found no difference in participants self-reports.

    Are Binaural Beats Safe To Use

    The first question that most people have after learning about binaural beats. Before we answer it, however, its essential to know one thing.

    Without headphones, binaural beats wont work.

    This is because the specific sound waves need to be played into each ear independently. Therefore, if you want to use binaural beats, use headphones.

    So, back to the question at hand. Yes, binaural beats are safe to use for most people.

    Although having said that, you need to consider the following:

    If you listen to anything using headphones, youre introducing sound directly into the ears.

    It doesnt matter whether youre listening to binaural beats, music or podcasts, you should never play anything too loud. The last thing you want to do is make yourself deaf!

    Potential Side Effects Of Binaural Beats

    Even if none of the situations mentioned above applies to you, and you think you are someone for whom binaural beats are safe to use, there are still some potential side effects that you might experience, which you need to be aware of.

    Firstly, there have been some cases where people who have used binaural beats have ended up feeling elevated levels of depression.

    Furthermore, there is a chance you could have short and small bursts of anger, confusion, or anxiety after listening to binaural beats.

    It is also important to note that binaural beats cant be something used to replace conventional therapy. It can complement and be a part of treatment strategies, but it wont be effective enough for certain conditions when used alone.

    How Do Binaural Beats Work

    Mental Health Boost – Brain Massage – Meditation Music

    When each ear hears a tone at a slightly different frequency, your brain tries to compensate by creating the perception of a third sound. This creation of a third sound is caused by the same part of the brain that helps you determine the location of a sound. To hear the binaural beat, you must have sound coming in each ear. If you take out one of your earbuds, youll no longer hear the binaural beat.

    When binaural beats are sustained over a period of time, they can synchronize with your brain waves. As a result, binaural beats can alter your brain wave activity as well as your levels of arousal.

    There are studies that show binaural beats induce delta activity in the brain and therefore, lengthen deep sleep. This leads to:

    • Improved quality of sleep
    • Increased ease of waking up
    • Feeling refreshed in the morning

    If youre looking for an alternative to guided meditation or whale noises as you drift off to sleep, try listening to binaural beats.

    Eeg Acquisition And Analysis

    EEG Recording

    The EEG data were recorded at a sampling rate of 500 Hz. We used an EEG amplifier with 19 Ag/AgCl electrodes using the 10-10 international system configuration. EEG data were referenced to the FCz electrode, and the ground channel was the AFz electrode.

    EEG Data Analysis

    All data analysis was performed using MATLAB R2017a with the OpenBMI toolbox and BBCI toolbox . The EEG data were down-sampled to 250 Hz. A band-pass finite impulse response filter was applied between 0.5 and 50 Hz, as this filter is stable and simple . In addition, a notch filter was performed at 60 Hz for the elimination of power transmission lines .

    The fast Fourier transform was performed to convert from the time domain to the frequency domain for spectral analysis. We analyzed the changes of auditory stimuli in five frequency bands: delta , theta , alpha , beta , and gamma bands , as the spectral elements of the EEG signals, are normally divided into these frequencies . However, we focused on the theta power, since we induced theta activity using the 6 Hz binaural beat. In addition, we investigated spatial changes in theta activity in seven brain regions: the prefrontal, frontal, central, temporal, parietal, occipital, and midline regions . These areas were chosen because the brain areas associated with binaural beats are not uncertain . The power in frequency bands was computed in each channel and averaged in seven regions.
