Is fan noise the same as white noise?
Fan noise contains broadband sound, but its mechanical hum and filtered tone make it less uniform than pure white noise.
Fan Noise for Sleeping
Recreate the steady sound of a familiar fan without leaving one running. Pick a preset, adjust the volume, and set a timer for bedtime or focused work.

Four Familiar Fan Sound Profiles
Box Fan is broad and steady, Desk Fan is lighter, Air Conditioner adds a lower mechanical bed, and Deep Fan emphasizes a softer low-frequency hum.
These generated profiles avoid short recording loops and continue until you stop them or the timer ends.
Masking an Unpredictable Room
A consistent fan-like sound can make traffic, hallway movement, or household changes feel less abrupt. Set it only as loud as needed to soften those changes.
The same steady background can also make a workspace feel more consistent when speech or small environmental sounds are distracting.
Frequently Asked Questions
Which fan preset is deepest?
Deep Fan and Air Conditioner emphasize lower frequencies; Desk Fan is lighter and Box Fan is broader.
Can I use fan noise without running a real fan?
Yes. The browser generates the sound while the page is open, without controlling or requiring a physical fan.
Will the fan sound repeat?
It is generated from looping noise buffers and steady tones designed to avoid an obvious short recording seam.
