Why so many people sleep with a fan
For millions of people the fan isn’t about cooling: it’s the sound. A fan makes a steady broadband rush 1, close to white noise but softer at the top, with a gentle motor hum and a slight movement in the air sound. Once you’re used to it, it can be hard to sleep without it, especially when travelling.
This page gives you that sound anywhere: in a hotel, in winter, or when a real fan would dry your eyes and throat.
Fan mixes
Fan, air conditioner or white noise?

| White noise | Brighter and perfectly even |
| Brown noise | Deepest and softest |
Travelling?
Bookmark this page or add MoodNoise to your home screen: it works offline after your first visit, so you have your fan in a hotel with bad Wi-Fi. With Pro you can download it as an audio file or keep it playing with your phone locked.
