Binaural Beat Generator
Generate binaural beats with adjustable frequencies, for listening with headphones.
Two tones, one perceived beat
Binaural beats arise when each ear hears a slightly different frequency, and the brain perceives a slow pulsing beat at the difference. This generates them with adjustable frequencies, and headphones are essential since each ear must hear its own tone.
Set the frequencies and listen with headphones.
The effect, honestly described
The binaural phenomenon itself is real and fascinating: two pure tones of slightly different frequency, one in each ear, produce the perception of a beat that is not physically present in the sound, created entirely by the brain combining what each ear hears. Many people enjoy listening to binaural beats for relaxation, focus or during meditation, and find the experience calming. In the interest of honesty, though, the widespread claims that particular beat frequencies reliably steer your brainwaves into specific mental states are not well supported by scientific evidence, which is limited and inconsistent. So they are best treated as something pleasant and possibly relaxing to listen to, rather than a proven tool for altering consciousness or mood. Enjoyed for the gentle, focusing quality many report, with headphones and at a moderate volume, binaural beats are a harmless and genuinely interesting bit of audio perception to explore.
Frequently asked questions
How do binaural beats create a beat that isn't there?
Each ear hears a slightly different pure tone, and the brain perceives a pulsing beat at the difference between them — the beat exists only in perception, not the sound.
Are the mental-state claims proven?
No — claims that specific frequencies reliably steer brainwaves into particular states are not well supported by evidence. They are best enjoyed as relaxing rather than a proven tool.
Do I need headphones?
Yes — the effect requires each ear to hear its own separate tone, so headphones are essential.
