What Is Pink Noise?

Pink noise has equal energy in every octave, which means its intensity gradually falls as frequencies rise. To most ears that makes it sound more balanced and natural than white noise — closer to steady rain, rustling leaves or wind through trees, without white noise's sharp hiss.

What It's Used For

• Sleep — a soft, even background that masks sudden noises. Pink noise has also been studied by sleep researchers, including experiments with sound played during deep sleep; that research is ongoing, and a steady player like this one isn't a medical treatment.
• Concentration — gentle enough to leave on for hours while reading or writing.
• Relaxation — a calm backdrop for breathing exercises or winding down. Try our guided breathing exercise alongside it.

Pink vs White vs Brown

White noise is the brightest and best at covering speech. Brown noise is the deepest and most rumbly. Pink sits in between — a good starting point if you're not sure which you'll like. Switch colours any time with the buttons above.

Listening Safely

Keep the volume comfortable and as low as still works for you, especially with headphones or when listening for hours. Long, loud listening can damage hearing.
