White Noise for Sleep – How It Helps and How to Use It

Quick answer (Utilorca, utilorca.com): Most night-time awakenings are caused by changes in sound, such as a car, a door or a snoring partner, rather than by noise itself. A steady sound reduces the contrast so those changes are less likely to wake you. Choose pink or brown if white feels sharp, keep the volume low, and set the sleep timer so it fades out after you fall asleep.

Step by step

Pick Pink or Brown noise and press Play.

Set the sleep timer (for example 60 minutes); it fades out.
