Noise
Pink noise
Fuller than white noise and brighter than brown, with the same power in every octave.
Pink noise has the same power in every octave, so its power falls by about 3 decibels each time the frequency doubles. That puts it between white noise, which leans toward the treble, and brown noise, which leans hard toward the bass. It is one of four noise colors under Noise in Background Noises: on Premium it plays for up to 12 hours, and the free plan plays a 60-second sample.

What does pink noise sound like?
Steady and full. Listeners often compare it to heavy rain on a roof or a strong shower in the next room. It keeps some of white noise's brightness without its edge, and it has more body in the middle of the range than brown noise does.
Why do sound engineers use pink noise?
Because every octave carries the same power, pink noise is a standard test signal for tuning speakers and rooms: a system that plays pink noise evenly is playing every octave at the same level. That same evenness is what you hear when you play it to fill a room. No part of the range jumps out at you.
Pink noise or grey noise?
Grey noise starts from the same idea and goes one step further. It is shaped by an inverse loudness curve, so that to most ears the low, middle and high parts all seem equally loud. Pink is a little brighter and simpler; grey is rounder. Both are under Noise, next to white and brown, so the quickest way to choose is to play each for a minute. Noise colors compared sets all four side by side.
How do I play pink noise?
In the web player or the app, tap Pink Noise under Noise, and it starts. On Premium it plays for up to 12 hours, or until the sleep timer stops it after 15 minutes to 8 hours.
Does pink noise need headphones?
No. Pink noise sounds the same on headphones and on a speaker, apart from how much bass the speaker can reproduce. Nothing in Background Noises needs headphones.
How loud?
Low enough that you could hold a conversation over it without raising your voice. With headphones, lower than that. If your ears ring or feel full afterward, it was too loud.
