Pink noise vs white and brown noise
Pink noise sits in the middle: less hissy than white noise, less bassy than brown noise. Its energy decreases by 3 dB per octave, which matches how our ears perceive sound, so it feels “even”.
Frequently asked questions
What is pink noise?
Pink noise has equal energy in every octave, so it sounds balanced and natural — similar to steady rain, wind or rustling leaves. It's softer than white noise and brighter than brown noise.
Does pink noise improve sleep?
Small studies have found that pink noise may increase deep sleep and improve memory the next day in some people. It's not a medical treatment, but many people find it relaxing.
Is it safe to sleep with noise on all night?
For adults, yes at a moderate volume — keep it quieter than a normal conversation (below about 50–60 dB). For babies, place the device at least 2 meters (7 ft) from the crib and keep the volume low, as recommended by the American Academy of Pediatrics.
Does it work with my phone screen off?
Yes on most phones: the sound is played like music, so it keeps going when the screen locks. If your phone stops it, keep the screen on with low brightness, or add the page to your home screen.
