What Green Noise Is
Green noise isn't a scientific standard like white or pink noise. The name became popular online for noise that's strongest around 500 hertz, the middle of the range people hear. Ours starts with pink noise and shapes it around that point, so both the hiss and the deep rumble are turned down.
Wide green noise keeps a little more of the highs and lows, for a more open sound.
Green Noise for Sleep
- Choose Green noise for sleep. It adds a little brown noise underneath and turns the tone down.
- Set the timer to 60 minutes or 8 hours. The sound fades over the last two minutes.
- Keep the volume low. Green noise sits where voices sit, so it covers talking nearby well at a modest level.
Green, Pink or Brown Noise?
- Green noise is the middle on its own: no hiss, little rumble.
- Pink noise covers the whole range with the highs turned down.
- Brown noise is mostly the low end, a deep roar.
Green Noise at Work or on a Bus
Green noise sits in the same range as voices, so a low level of it makes chatter nearby harder to follow. In an open office, try Wide green noise in headphones. On a bus or a train, plain green noise at a low volume blends the voices around you into the background without sounding like static.
Where the Name Comes From
Unlike white, pink and brown noise, green noise has no agreed definition. Sound designers use the name for noise centered on the middle of the range, and it stuck because people compare the sound to a waterfall or a breeze through trees.
