Green Noise for Sleep

Green noise concentrates its energy in the middle frequencies, where much of nature's ambient sound lives. That gives it the masking power of the other colors with a softer, more organic character that many people find easier to relax to than a bright hiss or a heavy rumble. It covers household and street noise while evoking the outdoors.

Set a low, comfortable volume and try the Waves toggle for a slow, tide-like swell that enhances the nature feel. Use the Sleep Timer to fade the sound out gently after you fall asleep, so it does not play all night unless you want it to.
