Pink noise - soft, airy sound - like steady rain on a roof
Pink noise sits between white and brown: it softens the higher frequencies so the sound is warm and balanced, like steady rain or wind through trees. It's the color most often studied for deeper, more restful sleep.
What is pink noise?
Pink noise drops about 3 dB per octave, so lower frequencies carry more energy than in white noise but less than in brown. To most ears it sounds natural and even - the rush of rain rather than the hiss of static.
Several small studies have linked steady pink noise during sleep to more time in deep, slow-wave sleep. It's a gentle, easy-to-listen-to choice for winding down.
