Binaural beat generator with presets
Two slightly different tones, one in each ear, create a perceived beat inside your head. Choose a band or set your own frequencies. Headphones are required.
How binaural beats work
If your left ear hears 200 Hz and your right 210 Hz, the brainstem perceives a 10 Hz wobble that is not present in either ear.
Brainwave bands
Delta 0.5–4 Hz: deep sleepTheta 4–8 Hz: drowsy, meditativeAlpha 8–13 Hz: relaxed, alertBeta 13–30 Hz: active thinkingGamma 30+ Hz: high attention.
What the research says
