Pink noise for sleep
Pink noise sounds like steady rain or wind through trees. It is softer and rounder than white noise, which is why many people find it easier to fall asleep to and live with all night. Chill Machine's Warm Pink Noise (One Hour) is one of our most-played sleep releases.

Is pink noise good for sleep?
Many people report that it helps them drift off and stay asleep by masking traffic, snoring and household noise. Some small lab studies have also looked at pink noise and deep sleep. For example, Ngo and colleagues (Neuron, 2013) played very short pink noise bursts timed to slow brain waves in 11 sleeping adults, which boosted deep-sleep brain activity and overnight word memory. That is very different from playing continuous noise at home, so treat it as interesting rather than proof.
What is the difference between pink and white noise?
White noise has equal energy at every frequency, which sounds bright and hissy. Pink noise turns the higher frequencies down by about 3 decibels per octave, so it sounds warmer and more natural. Our brown vs pink vs white noise guide compares all three.
Should I play pink noise all night?
Either works. Some people play a one-hour track while falling asleep, others prefer continuous sound to mask noises later in the night. Keep it at a low volume, and use a speaker rather than headphones if you can. The player above has a sleep timer.
Can I use pink noise for my baby?
Many parents do. Read our dedicated pink noise for baby sleep guide for volume and distance advice, and see Chill Machine's release made for little ones:
