How Binaural Beats Work
Binaural beats occur when you play two slightly different frequencies in each ear. Your brain perceives a third tone — the "beat" — at the difference between the two frequencies. For example, playing 300 Hz in one ear and 310 Hz in the other creates a 10 Hz binaural beat, which falls in the alpha brainwave range associated with relaxation and calm focus.
