Steady box fan sound for sleep, focus, and relaxation.
When enabled, the volume slowly decreases during the last minute before the timer ends.
A steady box fan sound can soften the contrast between quiet moments and intermittent noises such as traffic, doors, nearby voices, pets, or household movement. It does not soundproof a room, but it can make changing background noises feel less noticeable.
Use it while sleeping, studying, working, reading, or relaxing. Start at a low volume and raise it only until it comfortably covers the sounds you want to soften.

Choose a duration and a countdown will appear. When the time ends, the sound stops. The optional fade-out reduces the volume over the final 60 seconds so the ending is gentle rather than abrupt. You can cancel a timer at any time without affecting playback.
Make sure your device is not muted, try raising the volume slider, then reload the page and press Play again. If it still does not play, try a different browser.
