The Science Behind the Illusion: How Binaural Beats Work
At the core of binaural beats is the concept of brainwave entrainment, a process where external stimuli synchronize the brain’s electrical activity to a specific frequency. When exposed to binaural beats, the brain adjusts its dominant electrical activity to match the frequency difference between the two tones. For instance, if a 400 Hz tone is presented to one ear and a 410 Hz tone to the other, the brain perceives a binaural beat of 10 Hz. This aligns with the frequency associated with the alpha brainwave state, linked to relaxation and calmness.
