No nonsense, real fan noise with a black screen and no mid roll ads. Hope this helps you fall asleep and stay asleep or block out distracting sounds. Please be sure to listen at a safe volume.

Recorded from two household fans. Only processing is a bit of a cut on the low end rumble. Fairly closely matches the sonic signature of brown noise other than the low and high ends which have been attenuated to make for a more comfortable listening experience.
