It’s no surprise that people are getting tired of working at home. I’ve been feeling slumped with full online school, coding, and building projects. Finish this later

When you hear two tones of slightly varying frequencies your brain processes the differences of those frequencies as another tone. For example: If you are listening to one tone that is 450 Hz in your left ear, but 460Hz in your right ear, your brain will process and hear a 10 Hz tone on top of the 450 Hz and 460 Hz tones. Because of these binaural beats your brain will eventually sync up with the 10 Hz tone and start oscillating more at that frequency.

This means that the specific brainwaves around that frequency range will become stronger and have an effect on the rest of your body, mood, etc.

For our example of a 10 Hz binaural beat, your Alpha waves would become stronger as your brain starts to synchronize more at that frequency.

Binaural beats leverage this neuroscience to get you feeling more refreshed through the day. Even as I write this article, I’m listening to BrainFM to recharge me after a tiring day.

But this article isn’t an ad for BrainFM, I want to further explore the potential of binaural beats as a consumer treatment for stress, mild anxiety, and lethargy. As well as its potential to augment focus, productivity, and sleep.

How Can Binaural Beats Help Us?

Your neural oscillations (now referred to as brainwaves) being in balance is vital to your mental health. Their frequencies becoming imbalanced can cause lots of shit to happen in your brain like depression, anxiety, etc. I go deeper into what happens in this article.

Binaural beats have the potential to resync your brainwaves and given enough time. Not only that, they can supercharge some of your brainwaves to get you refreshed and focused.

Let’s breakdown why this happens.

Brainwaves are categorized by the speed at which neurons are communicating with each other (Hz) and their power is measured by their electrical potential (uV, micro voltage).

If someone’s Alpha waves are ~14 Hz (normal is 7.2 Hz to 12 Hz) that would mean that their Alpha wave is out of balance. One method of restoring this balance would be to listen to a binaural beat that has a frequency of 7.5 Hz to 12 Hz.

Your brain would start to sync to that frequency, and all brainwaves at that frequency would be amplified. Do this enough times and eventually, you can start to retrain your brainwaves to be in balance once again.

When certain frequencies are amplified, you would feel the effects correlated with the brain wave more. For example, if your beta brainwaves were amplified with 30 Hz binaural beats, you would feel more focused. If your theta waves were stimulated, you would probably start to drift into a meditative state and feel calmer.

However, serious illnesses like schizophrenia, manic depression, bipolar disorder, among other much more serious mental illnesses can’t be solved with binaural beats. You’ll need a lot more than brainwave entrainment to unravel those complex illnesses.

The Future of Binaural Beats

The future of binaural beats is interesting because of the core concept of them. Essentially, you are feeding your brain a specific frequency, and eventually, your brain syncs up to it.

In theory, you could probably augment this phenomenon with some other fancy neuroscience. And that’s exactly what NuCalm did.

NuCalm is a company that specializes in destresses its customers using binaural beats and a special biosignal processing disk. What it does is tell the body to produce extra GABA which is a neurotransmitter that counters the effects of cortisol and adrenaline (stress hormones).

NuCalm leveraged binaural beats and specialized them for destressing their customers. This is the potential of binaural beats, and they can go so much further than this.

For example, imagine a company like OmniPemf started to use binaural beats with their product. OmniPemf has the most popular electromagnetic stimulation device meant to destress its clients. Their product could be better if they leveraged binaural beats to ease their clients into a state where their device, NeoRhythm could work best.

However, none of this can happen without more studies in binaural beats. I truly believe that NuCalm could pave the way for binaural beats with more research and evidence backing up this technology.

Key Takeaways:

  • Binaural beats are an auditory illusion which help sync up your brain
  • Binaural beats are used to amplify and retrain your brainwaves which leads to positive effects on your mood, mental state, focus, etc.
  • The future of binaural beats are fairly extensive. If there’s more science to back it up, there’s a lot of potential for more neuroscience companies to adopt them into their products.
