Binaural Beats for Sleep

Updated September 23, 2026 | Luke Archer, maker of Orin

Binaural beats are two tones at slightly different pitches, one in each ear. Your brain hears the difference between them as a slow pulse. If the left ear gets 200 Hz and the right ear gets 204 Hz, you perceive a 4 Hz beat that isn't actually in either track.

People use slow beats at bedtime because they sit in the same range as the brain's own sleep rhythms. The idea is simple: give your mind something slow and steady to settle into.

What frequencies people use for sleep

A common approach is to start a little higher, around alpha or theta, and let the beat drift lower as you fall asleep. The beat frequency is the difference between the two tones. The tones themselves, called carriers, are usually a few hundred hertz.

What the research says

Honestly, it's mixed. A 2023 systematic review in PLOS ONE looked at 14 studies on whether binaural beats pull brainwaves toward the beat frequency. Five supported the idea, eight did not, and one was mixed. The authors concluded the question can't be settled yet, mostly because studies used very different methods.

Studies that measure how people feel, rather than their brainwaves, look more encouraging. A 2019 meta-analysis of 22 studies in Psychological Research found a moderate overall effect on memory, attention, anxiety, and pain perception. Theta beats were linked to lower anxiety, and longer listening tended to work better than short exposure.

The more consistent evidence is for slow breathing. A long exhale activates the parasympathetic nervous system, which lowers heart rate and helps the body shift toward rest. A 2018 review of 15 studies linked breathing under 10 breaths a minute to more relaxation and less anxiety.

That's why Orin pairs the two. The breath does the physical work. The sound gives your attention somewhere to rest. Treat it as a tool, not a cure, and notice how you feel.

How to use them at night

1. Use headphones or earbuds. The effect needs a separate tone in each ear. Soft sleep earbuds or a sleep headband work best.
2. Keep the volume low. Just loud enough to hear. You're not trying to cover the room.
3. Breathe slower than feels natural. In for about 4, out for 6 to 8. The exhale matters most. See breathing exercises for sleep.
4. Decide how long it should play. Some people want sound only until they're asleep. Others wake up when it stops and prefer it to run all night.
5. Keep the screen off. Bright light at bedtime works against you.

Fade out or play all night?

Both work. It depends on you.

• Fade out suits light sleepers who get woken by sound, and anyone who just needs help falling asleep.
• All night suits people who wake up when a room goes silent, or who live somewhere noisy.

Drift, Orin's sleep mode, does either. By default the soundscape dims with you and fades to silence. Switch it to play until you stop it, and it keeps going with the screen off.

Binaural beats vs white or brown noise

Noise masks sounds in the room. Binaural beats add a slow pulse for your attention to follow, and they need headphones. They are not either-or. Orin layers a warm brown-noise bed under the binaural tones, so you get both.

Binaural beats are not a treatment for insomnia or any sleep disorder. If sleep problems are ongoing, talk to a doctor. Avoid binaural beats if you have epilepsy or a seizure disorder unless your doctor says it is fine.
