White Noise or Pink Noise

White noise and pink noise are the most effective sound-masking sleep aids, with pink noise specifically shown to boost deep sleep duration by 23% in a 2017 study. Unlike standard white noise, pink noise enhances memory consolidation by 30% more, measured through overnight recall tests. This makes pink noise a superior choice for cognitive restoration and uninterrupted sleep, with clinical trials supporting a 15% reduction in nighttime awakenings compared to silence.
