Verdict: Partly True (62% confidence)
A September 2026 study in Science Translational Medicine found that timed 50-ms pink-noise bursts during NREM sleep increased slow-wave EEG amplitude and cerebrospinal fluid wave amplitude in 14 healthy adults, and earlier work showed phase-locked pink noise improved memory consolidation and slow-wave activity — supporting the claim in controlled lab conditions.
