This phenomenon was discovered many years ago, which you can read more about in our free user guide – available here. The brainwaves follow along at this frequency, thus the term brainwave entrainment. So if we send a 200 Hz signal to the left ear and a 215 Hz signal to the right ear, the brain will essentially create a third signal that represents the mathematical difference between the two, which in this case is 15 Hz.

This tone/hum varies in prominence depending on the frequency.īinaural beats is a natural science in that the processing happens automatically in the brain.

When one frequency signal is sent to the left ear through headphones, and one frequency signal is sent to the right ear through headphones, the brain perceives the mathematical difference between the two signals and creates binaural beats.Īudibly, this sounds like a vibrating tone/hum. This is an audio phenomenon that occurs naturally in the following way: There are 5 core types of binaural beats, which will cover in this article.īut just so we're clear before we get into the categories, note that there is only one form of binaural beats.
