Binaural beats for sleep
A slow beat under a bed of noise: delta for deep sleep, theta for drifting off, layered over brown or pink noise with a fade-out timer. Free, endless, no ads.
Headphones needed for the beat — use them for the first 20-30 minutes with the sleep timer, then plain noise takes over.
1 Pick your sleep beat
2 Add a noise bed
The noise does the heavy lifting for sleep: it masks the door slams, pipes and traffic that wake you in the lighter sleep stages. Brown noise is the community favorite for night; pink is a touch brighter. The beat hums along underneath.
3 Set the sleep timer
In the player bar below, set a 30 or 45 minute timer — the sound fades out gently once you're asleep. That solves the headphones problem too: beat + noise while you fall asleep, silence (or a speaker with plain noise) after.
What to actually expect
Honest version: the research on binaural beats for sleep shows small, mixed effects — some studies find people fall asleep a little faster or feel less pre-sleep anxiety, others find no difference from ordinary relaxing audio. What has solid evidence is steady noise masking (fewer micro-wakes from environmental sounds) and a consistent wind-down ritual. This page stacks all three, with the proven parts carrying the experimental one — and everything here is free, so the experiment costs you nothing but one night.

Frequently asked questions
Which binaural beat frequency is best for sleep?
The convention is delta (1-4 Hz) for deep sleep and theta (4-8 Hz) for the drifting-off phase. Our Deep Sleep preset uses 2.5 Hz and Drift Off uses 6 Hz. That said, individual responses vary — some people find any tone irritating at bedtime and sleep better with plain brown noise. Comfort wins over theory, every time.
Do I have to wear headphones all night?
For the binaural effect, yes — it only exists when each ear gets its own tone. Sleeping in earbuds is uncomfortable for many people, so a practical routine: headphones for the first 20-30 minutes with a sleep timer (set it in the bar below), then the beat fades out and you can switch to plain noise on a speaker for the rest of the night.
Do binaural beats actually make you fall asleep faster?
The honest answer: evidence is mixed. Some small studies show modest improvements in sleep onset and anxiety before sleep; others show no effect beyond relaxing music. What has stronger evidence is the combination we recommend: a steady masking sound (noise) plus a consistent wind-down ritual. The beat is a reasonable, free thing to add on top — not a sleep drug.
Can I mix binaural beats with brown noise?
Yes — that is exactly what this page is built for. The beat plays underneath the noise; the noise masks bedroom and street sounds (the part with the strongest evidence) while the low carrier tone adds a gentle texture. Use the noise-bed tiles below and keep the overall volume low.
Is it safe to play binaural beats while sleeping?
For most people, yes — it is quiet sound. Keep the volume low (you should be able to hear a normal voice over it), use a sleep timer rather than all-night playback in headphones, and if you have epilepsy or a seizure history, check with your doctor about rhythmic stimulation first.
