Pink noise is a sound with frequency characteristics similar to natural sounds like rain or a waterfall. These characteristics are believed to reduce ambient noise and promote better sleep and improved concentration. Some studies have shown that pink noise improves sleep quality, making it a popular choice for studying and meditating.
