How do Binaural Beats entrain the brain?

When two slightly different pure sine wave frequencies are presented independently to each ear through stereo headphones (for example, 210 Hz in the left ear and 220 Hz in the right ear), the brain's auditory processing center (specifically the superior olivary complex) integrates the two signals.

Instead of hearing two isolated tones, your brain perceives a rhythmic, phantom third tone called a Binaural Beat, oscillating at the exact mathematical difference (10 Hz). Through a neurological phenomenon called Frequency Following Response (FFR), your brainwave patterns naturally synchronize to this beat, gently nudging your mental state into deep rest, focus, or meditation.
