Why a fan helps people sleep
Many people grew up sleeping with a fan on and now find silence hard. A fan makes a steady, airy hum that covers noises in the house and the street. It's close to brown noise, with the texture of a real motor.
A fan without the fan
- No cold air blowing on you in winter.
- Works in a hotel, on a trip or where there is no fan.
- No dust, no running cost.
How to use it
Set the volume just above the noise you want to cover. For more white-noise character, try white noise; to add rain, open the web app, which mixes up to 3 sounds.
Questions
Is this a real fan recording?
Yes. It's a box fan recorded at medium speed and looped so you don't hear where it restarts.
Can I play it all night?
It plays until you press pause, as long as the tab stays open. For the screen-off, all-night version, use the Brezi iPhone app.
Is fan noise good for babies?
Many parents use it. Keep the volume low and the phone at least 2 m (7 ft) from the crib. See the safety guide.
