  • Intermittent noise.
  • Impulsive noise.
  • Low-frequency noise.

Can pink noise help you sleep?

Pink noise has potential as a sleep aid. In a small 2012 study in the Journal of Theoretical Biology , researchers found that steady pink noise reduces brain waves, which increases stable sleep. A 2017 study in Frontiers in Human Neuroscience also found a positive link between pink noise and deep sleep.
