Binaural Beats are also known as Binaural Tones. They are sounds/tones which produce specific stimuli in your brain, but that will not suffice so lets dive into them more deeply.

How Do Binaural Beats Work?
Basically, your brain when perceiving two tones with subtle differences between them (or with frequencies slightly different than each other) will pick up the difference between the two frequencies when the difference is < or = to 30Hz.
When this happens, the brain will hear this difference as a binaural tone/beat.


But this is where they effect the brain.

You have probably heard of all the different brain waves which tend to correlate to different patterns of thinking. The breakdown is below;

Gamma Waves (> 40Hz) are usually associated with fear, perception, problem solving and strong mental activity

Beta Waves (13-39Hz) are associated with busy/anxious or nervous thinking, active concentration, paranoia and arousal

Alpha Waves (7-13Hz) are associated with a state of relaxation while being fully awake. Possible pre-sleep, REM sleep, & Dreams

Theta Waves (4-7Hz) are associated with deep meditation, relaxation and NREM sleep

Delta Waves (
