Binaural beats are an emerging form of soundwave therapy and are considered auditory illusions. Studies have shown the effect on the human brain by activating certain systems in it. Different tones create different responses for the listener and bring with them many benefits, such as:
Lowering blood pressure.
Helping manage pain.
There are four different brainwaves that are affected at different levels of hertz, so you get to choose the desired benefit. In general:
Binaural beats in the delta (1 to 4 Hz) range help support deep sleep and relaxation.
Binaural beats in the theta (4 to 8 Hz) range help reduce anxiety and put you in meditative, relaxed states. They’re also known to help the listener achieve REM sleep.
Binaural beats in the alpha frequencies (8 to 13 Hz) encourage relaxation, and help create a stronger state of positivity.
Binaural beats in the lower beta frequencies (14 to 30 Hz) are linked to increased concentration, improved memory, and aid with problem solving.
As you can see, there are clear benefits to using binaural beats. But there is another side to every coin and we need to be aware of the risks of binaural beats as well as the benefits.
So, what negative things can come of them?
There is not a whole lot of risks to binaural beats unless you have epilepsy or listen to them at a high volume. Hearing loss can happen if you’re listening to anything at 85 decibels or higher.
Many do warn against faux-beats on Youtube; fake binaural beats that mess with your brain waves in an uncontrolled manner that bring on nightmares and sleep paralysis. So, make sure you’re listening to legitimate binaural beats for the best results.
Real binaural beats can only be heard when both ears are listening. Two tones—one in each ear—have to be used to generate that third tone. So, what you hear in one ear should be different than what you’re hearing in both ears, at the same time.
Whether you’re looking to hyper-focus, relax, or ease pain, binaural beats are a safe, go-to source for help.
