Binaural beats involve playing different sound frequencies to each ear, with the brain averaging these to create an intermediate frequency that may enhance learning.

“Here, we're talking about the use of binaural beats in order to increase our level of alertness or our level of calmness. Now, that's important to underscore because it's not that there's something fundamentally important about the binaural beats. They are yet another way of bringing the brain into states of deep relaxation through low-frequency sound or highly alert states for focused learning with more high-frequency sound. They're effective, but it's not that they're uniquely special for learning. It's just that they can help some people bring their brain into the state that allows them to learn better.”
