Box fan vs ceiling fan, and ours
Real fans sound different by size and speed, so here is what each one sounds like and how ours compares
| Fan | What you hear |
|---|---|
| Box fan | A full, steady rush with a low hum. The box fan sound is a common choice for sleep. |
| Ceiling fan | Softer and slower, with a gentle whoosh as each blade passes, and sometimes a tick from the mount. |
| Desk fan | Smaller and higher in pitch, with more whine from the motor. |
| Tower fan | A smooth, airy hiss with little hum, close to pink noise. |
| Our fan | A produced fan sound in a loop of about 3 minutes, in 48 kHz stereo. It loops with no gap. |
| Fan sound effect | A WAV download gives a clean, steady fan sound effect with no voices or music in it. |
Sleep with a fan sound
Travel and hotel rooms
Your phone gives you a fan sound in any hotel room. Pack a charger, start the timer, and put the phone across the room.
Timer and lock screen
Set 30, 60, or 120 minutes, and the sound fades out over the last minute. We do not promise play on the lock screen, so keep the browser tab open.
Keep it low
A fan sound for sleeping should be quiet. Long, loud listening can damage hearing, Cleveland Clinic says, so use the lowest level that covers the room.
No box to buy
A fan sound machine for sleeping, or a box fan sound machine, plays a loop like this one from a small speaker. The phone or laptop you already have does the same job.
Questions
- Is it bad to sleep with a fan on?
- A real fan has downsides: the Sleep Foundation names dust, pollen, and dry air. A fan sound has none of them, because no air moves. The level still matters, so keep it low.
- Why do people need fan noise to sleep?
- Many people learn to fall asleep with a fan, and then quiet feels strange. The steady hum works by masking: it makes sudden sounds such as traffic or a door less sharp.
- Is fan noise white noise?
- Not exactly. White noise has the same energy at every frequency. A fan has more low sound, a motor hum, and a blade flutter. Many people still call it a white noise fan, because it does the same job.
- How can I get fan noise without a fan?
- Press Play. The sound plays in your browser, so there is no cold air and no fan to clean.
- How loud should fan noise be for sleep?
- Just loud enough to cover the sounds that wake you, and no louder. A browser cannot measure decibels, so judge by ear and start low. If you hear ringing in your ears, see a doctor or an audiologist. These sounds are not a medical device or medical advice.
- Can I play fan noise on my phone all night?
- Yes. With No timer, the sound plays until you stop it. Keep the browser tab open and the phone on charge. Playback with the phone locked is not promised, so test it once before a trip.
- What is the difference between fan noise and white noise?
- Fan noise vs white noise: white is a flat, bright hiss, made from exact math. Ours is a produced fan sound, with more low sound and less hiss.
