How Binaural Beats Work
Binaural beats are created by playing two slightly different frequencies in each ear — for example, 200 Hz in one ear and 210 Hz in the other. Your brain perceives the difference as a 10 Hz rhythmic beat.
This effect is often called brainwave entrainment and is commonly associated with relaxation, focus, or sleep.
Frequently Asked Questions
Answers about binaural beats, safety, and how to use the generator.
Do I need headphones for binaural beats?
Yes. Headphones are required so each ear receives a slightly different frequency, creating the binaural effect.
How long should I listen to binaural beats?
If you’re new, start with 10–15 minutes. Many users prefer 20–30 minute sessions once they get used to it.
Longer sessions are also fine for relaxation or sleep, as long as the volume is comfortable.
Which frequency should I choose?
Choose a frequency based on your goal — sleep, relaxation, focus, or energy.
You can explore detailed explanations on our page about binaural beat frequencies.
Learn more about brainwave frequencies →Are binaural beats safe?
Generally yes, when used responsibly and at comfortable listening levels.
Avoid use if you have epilepsy or a history of seizures. If you have a medical condition, are pregnant, or use a pacemaker, consult a healthcare professional before use.
Do not listen while driving or operating machinery, as binaural beats may promote relaxation or drowsiness.
Why is the download limit set to 60 minutes?
You can stream sessions up to 8 hours in your browser, but downloads are limited to 60 minutes.
Generating high-quality audio files is resource-intensive, and this limit helps ensure stable performance across devices.
How does PureBinaural generate the audio?
PureBinaural generates precise sine waves in real time using the Web Audio API, with each channel controlled independently.
Sessions are rendered at 44.1 kHz, normalized to safe levels, and include smooth fade-in and fade-out.
Is using PureBinaural private?
PureBinaural runs entirely in your browser, so no audio data leaves your device.
No accounts, no cookies, and no personal data collection.
