About Fan Noise
Many people cannot sleep without a fan running. It is not always about the air — it is the sound: a soft, steady hum that covers the street, the neighbours and the small noises of a house at night.
This page plays that fan sound without a fan. Press Play and it hums until you stop it. It is handy in winter, when you do not want cold air, in a hotel room, at a friend's place, or anywhere you cannot take your fan.
The sound is made live in your browser — there is no recording. It starts at once, and there is no click or jump every few minutes.
Features
- Fan first — the page opens on the fan, ready to play
- Soft hum with blade flutter — low, steady noise with a gentle hum and a light flutter, like a real fan
- Five other sounds — white, pink and brown noise, rain and ocean waves, one tap away
- Sleep timer — stop after 15, 30, 60 or 120 minutes, 3 hours or 8 hours
- Soft fade — the sound fades in and out, so it never starts or stops with a jump
- Remembers your settings — your sound and volume are saved in this browser
- Free and private — no sign-up, no download, no ads in the sound
How the fan sound is made
A real fan makes three kinds of sound: air rushing past the blades, a low hum from the motor, and a soft "whup-whup" as the blades pass. This page builds the same three parts from noise:
- Air — random noise with the high tones cut off above about 480 Hz, so it sounds soft and deep, not hissy.
- Hum — a gentle boost around 120 Hz, the low tone of a motor.
- Blade flutter — the volume moves up and down a little, about 7 times a second, like blades passing.
The noise is drawn fresh each time you press Play, in a long stretch of about 20 seconds, so you will not hear a pattern repeat.
Fan, brown noise or white noise?
All three are steady sounds that cover other noise. They feel different:
| Sound | What it is like | Many people choose it for |
|---|---|---|
| Fan | soft, low hum with a light flutter | sleep, if they are used to a fan |
| Brown noise | deep rumble, no flutter | sleep, long work sessions |
| Pink noise | even "shhh", like steady rain | sleep, study |
| White noise | bright hiss | covering voices in a loud room |
If the fan feels too busy, try brown noise — it is just as deep, but perfectly smooth.
Sleeping with a fan sound: good to know
- Keep it low. Set the volume so the street and the house fade into the background. It does not need to be loud.
- Speaker away from your head. A phone on the night table or a small speaker across the room is more comfortable than headphones.
- Keep this tab open. You can use other tabs or apps, but closing the page stops the sound.
- Phones and screen lock. Some phones pause web audio when the screen locks. If the sound stops, keep the screen on with low brightness, or plug the phone in.
- For babies: keep the volume low and the phone or speaker away from the crib. If you have questions about your baby's sleep, ask your doctor.
This page is for relaxing and covering noise. It makes no health claims.
Frequently asked questions
Is this a recording of a real fan?
No. The sound is made in your browser from noise, a low hum and a gentle flutter. That is why it starts at once, and there is no join you can hear where a recording would start again.
Will it cool the room?
No — it is only the sound. It does not move any air. That is the point for many people in winter: the familiar hum, without the cold breeze.
Why do people sleep better with a fan on?
Many people simply got used to it. A steady sound also makes sudden noises stand out less, so a door or a car is less likely to bother you.
Can I play the fan sound all night?
Yes. Set Stop after to 8 hours or to Never, and keep the tab open. On some phones the sound stops when the screen locks; keep the screen on or plug the phone in.
Can I mix the fan with rain?
On this page you play one sound at a time. To mix a fan hum with rain, wind or other sounds, use the Ambient Sound Mixer.
Is it free?
Yes. No sign-up, no app and no ads in the sound. The page needs the internet to open, but the sound itself is made on your device.
