There isn’t a lot of scientific research on pink noise, though. Deep sleep supports memory and helps you feel refreshed in the morning. In a small 2012 study in the Journal of Theoretical Biology, researchers found that steady pink noise reduces brain waves, which increases stable sleep.Ī 2017 study in Frontiers in Human Neuroscience also found a positive link between pink noise and deep sleep. You can listen to them on a computer, smartphone, or sleep machine like a white noise machine. These sleep-inducing sounds are known as noise sleep aids.
