Mid-range frequencies have been linked to attention. Higher frequencies reportedly boost your brain waves into a “gamma” state which may make you more alert, focused, or better able to recall memories. Generally speaking, low-frequency waves are linked to “delta” and “theta” states which can boost relaxation and improve sleep. Your brain has five different types of waves. Some people believe that once binaural beats introduce a new frequency to your brain, your brain waves feel compelled to sync to it, effectively launching you into a different “brain state.” In other words, what the heck do they do to your brain? “The question is,” says Smith, “do they influence cognitive processes?”
No one is arguing whether or not they exist, by the way. Smith, PhD, an assistant professor of psychological science at the University of North Georgia in Gainesville, Georgia, who has studied binaural beats. (In this case, it would be 10 Hz.)Īlthough it sounds hard to believe, essentially, “you’re hearing something that’s not really there,” explains Troy A.
There, the tones “squelch” together into a so-called “beat” at a perceived new frequency. When you play a tone with a slightly different frequency into your left and right ear - say, 200 hertz (Hz) in one and 210 Hz in the other - they travel separately to your inferior colliculus, the part of your brain that gathers auditory input. “Binaural” means “relating to both ears.” Also called “brain entrainment,” they’ve largely been considered an oddity more than a useful medical treatment. While it may be easy to dismiss binaural beats as the next wellness gimmick currently enjoying its 15 minutes of fame, there’s some science behind these sounds… which aren’t actually sounds at all.Įxperts credit a Prussian meteorologist named Heinrich Wilhelm Dove for discovering binaural beats way back in 1839. These otherworldly beats are big on YouTube, promising to cure everything from insomnia to fear, while improving poor memory and an anemic happiness level. If you’ve ever done an online search for “stress relief” or “anxiety cure,” chances are you’ve already heard of binaural beats. “ are one of the best things to happen to me.” “I was happier, better rested, and not in pain,” she says. A month of binaural beats later, Trimberger says she noticed something miraculous. Thinking “it couldn’t hurt,” she listened and found the experience was better than she expected.Īfter just 10 minutes, she became relaxed enough to better tolerate her pain.Įncouraged, she listened again, night after night.

When Trimberger first learned about binaural beats, she says she began searching and found a free recording online. “Anxiety and stress are some of my largest triggers,” she says, adding that the medications she’s tried have only left her groggy and feeling “out of it.”īut nine months ago, Trimberger found something that did help her feel better: a soundwave phenomenon known as binaural beats - subtle, surreal beats that are sometimes cocooned in relaxing music and seem to pulsate deep inside the brain. Trimberger, who owns a company that makes small-batch beauty products, also has trigeminal neuralgia - a facial nerve disorder often called the “suicide disease” due to its painful and hard to control flare-ups. “I find it hard to be motivated and am generally jittery,” she says. How these otherworldly sounds may help you hear your way to a happier, healthier you.įor as long as she can remember, Jessica Trimberger has lived with anxiety.
