Binaural Beats Generator
Play binaural beats — two slightly different tones that create a perceived beat.
A beat that exists in the mind
Binaural beats are created by playing a slightly different frequency in each ear, so the brain perceives a third, slow beat from the difference between them. This generates them in your browser, and headphones are essential since the effect depends on each ear hearing a separate tone.
Set the frequencies and listen with headphones.
What they are, and an honest note on the claims
The binaural effect is a genuine and interesting perceptual phenomenon: when each ear receives a pure tone of slightly different frequency, you perceive a pulsing beat at the difference between them, even though no such beat exists in the actual sound. Many people listen to binaural beats for relaxation, focus or meditation, and find the experience pleasant. It is worth being honest, though, that the popular claims — that specific beat frequencies reliably alter brainwaves to induce particular mental states — are not well supported by scientific evidence, which remains limited and mixed. So they are best approached as something people find relaxing or enjoyable to listen to, rather than a proven tool for changing your mental state. Enjoyed for the pleasant, focusing quality many report, with headphones and at a moderate volume, binaural beats are a harmless and intriguing bit of audio.
