Binaural Beats: Are They Truly Effective in Calming Your Mind?

If you're aiming for complete relaxation, reduced stress, anxiety management, improved sleep quality, or even enhanced focus, it might be worth exploring binaural beats. These beats, however, are not the kind you'd typically hear in a club. In fact, when properly executed, they might not produce any noticeable beat at all.

"Binaural beats involve two distinct sound frequencies being played simultaneously to create the perception of a single tone. When each ear receives a different frequency (one in each ear), the brain detects the difference between the two and tunes into that new frequency," explains Melissa Gentry, life coach and CEO of Healing the Love. For instance, if your right ear hears a 290-hertz tone and your left ear hears a 300-hertz tone, your brain will perceive a 10-hertz tone as a result."

"This is a very low-frequency sound wave — one that you can't actually hear," explains sleep specialist and clinical psychologist Dr. Michael Breus in an email. "However, your brain can still be influenced by it, even without hearing it."

The concept is that these sound waves prompt neurons in the brain to synchronize with the same frequency, guiding individuals toward achieving a specific goal. There are five distinct categories of sound frequency patterns that are believed to produce different effects:

"Each frequency affects our brain in a unique way, so it is recommended to listen to the frequency range that aligns with your desired outcome," advises Gentry.

Do Binaural Beats Work?

I decided to experiment with binaural beats for a week, hoping they would calm my dreams, reduce my teeth-grinding, improve my sleep quality, and give me an afternoon energy boost. While I didn't notice significant changes right away, this lack of immediate results isn't unusual.

"The expectation is that results should be immediate. However, I believe the brain needs time to adjust, so my personal advice would be to try it for 1-3 days," says Breus. Since I tend to be quite persistent, I plan to continue using binaural beats to see if the benefits manifest over time.

Elizabeth Davidson from Moline, Illinois, uses binaural beats nearly every day, and she's just one of many people who swear by their effects. "At work, I often use a concentration-enhancing binaural beat, which helps me focus better than any other method," she shares via email, adding that she prefers to get her beats from the Binaural Chakra Therapy app.

Although this field is still emerging and lacks conclusive proof, some studies suggest that binaural beats may help reduce anxiety, which is promising for those struggling with the condition. Nevertheless, other treatments should not be discontinued. "There is also some evidence that binaural beats could influence hormonal production," notes Breus.

A 2020 study in the journal eNeuro concluded that binaural beats had no effect on mood or brain wave synchronization and questioned whether the positive results seen in other studies were simply a placebo effect. "However, we did observe that binaural beats created different connectivity patterns compared to a monaural beat control. Whether these patterns have meaningful implications for cognitive enhancement or mood modulation is still unclear," the researchers stated. Nonetheless, experts remain optimistic about potential applications of binaural beats in brain-related areas, such as prevention or treatment for depression, migraines, and other conditions.

Exploring Binaural Beats

Thankfully, there is minimal evidence suggesting any negative effects of binaural beats, leaving room for ongoing exploration, adjustment, and experimentation. You can easily start experimenting with just a pair of regular headphones or earbuds. "Each ear receives sound at slightly different frequencies (often paired with soothing background sounds)," says Breus.

A variety of binaural beats are available online for free or for purchase, or you can even create your own using a beat generator. Just ensure that the total frequencies stay below 1,000 Hz. "As with anything, moderation is key — don't overdo it," advises Gentry. "Since the brain takes about seven to ten minutes to sync with the audio, give yourself at least 15 to 30 minutes of listening time to experience the benefits."

So, don’t expect immediate results if you’re in a hurry. "The principle behind binaural beats is brain training, which requires consistency and practice for meaningful changes," Gentry explains. "So, put on some beats, tune into the soundwaves, and enjoy the transformative experience."
