Pink Noise

Pink noise has equal energy per octave, meaning lower frequencies are more prominent, creating a deeper, more balanced sound like steady rainfall or wind. Multiple studies have shown pink noise can enhance deep sleep and improve memory consolidation during rest. Its natural-sounding quality makes it less fatiguing for extended listening compared to white noise. Research from Northwestern University found that pink noise synchronized with brain waves during deep sleep improved memory in older adults. Ideal for: sleep enhancement, relaxation, long work sessions, meditation.
