Larger studies are necessary to confirm the clinical benefits of pink noise. However, it is important to note that many of these studies included a small number of participants. A small 2020 study indicates that pink noise may improve work efficiency, continuous performance, and working memory. However, the authors note that pink noise did not change the participants’ self-reported sleep quality, mood, or alertness.Ī similar 2020 study found that pink noise helped participants fall asleep and achieve deep sleep faster.

In a small 2021 study, using a white noise device in the bedroom significantly improved the participants’ sleep. One major topic of research is the use of white noise in improving the quality of sleep. Researchers have investigated the potential benefits of white noise more than those of the other noise colors. Some possible benefits include: White noise potential uses The benefits of white noise and pink noise have been a popular topic of research.
