Binaural Beats

How binaural beats help you fall asleep

By The Nidra TeamUpdated on 4 min read

Binaural beats use a small frequency difference between your ears to create a slow perceived pulse. Here is what that does at 3, 6 and 10 Hz, and how to use it tonight.

What a binaural beat actually is#

When your left ear hears a steady tone and your right ear hears one slightly higher, your brain perceives a third, slower pulse: the difference between them. Play 200 Hz on the left and 203 Hz on the right and you perceive a 3 Hz beat.

That perceived pulse is the whole point. It is slow, regular and unremarkable, which makes it easy to stop paying attention to.

The three frequencies Nidra uses#

3 Hz — deep settling#

The slowest option in Nidra. Best when your body is tired but your thoughts will not slow down. Use it as you get into bed.

6 Hz — drifting#

A middle setting for the space between awake and asleep. Pairs well with rain or a low drone.

10 Hz — quiet focus#

Not a sleep frequency. Use it for a wind-down routine, reading, or an afternoon reset.

How to use it tonight#

  1. Use headphones. Binaural beats do not work through a single speaker.
  2. Keep the volume low — just above the room.
  3. Pick 3 Hz, start a sleep timer, and stop monitoring whether it is working.

What we do not claim#

Binaural beats are not a treatment. Research on them is small-scale and mixed, and Nidra is a comfort tool, not medical care. If you have persistent insomnia, talk to a clinician.

Frequently asked

Do binaural beats need headphones?

Yes. Each ear must receive a different tone, so speakers will not produce the effect.

Which frequency is best for sleep?

3 Hz is the slowest and most settling option in Nidra. 6 Hz suits the drift into sleep, and 10 Hz is for wind-down rather than sleep.
