Pink, Brown, White & Green Noise — Find the Right One for You
Not all noise colors work the same way. Pink noise enhances deep sleep. Brown noise masks low-frequency disruptions. White noise is the strongest all-round acoustic shield. Green noise mirrors natural environments. The difference isn't just preference — it's physiology, room acoustics, and what specific sleep problem you're trying to solve.
Every guide here is grounded in peer-reviewed research, clearly sourced, and regularly updated. The starting point for most people is the complete noise color comparison — it maps each color to specific sleep problems, room types, and safe volume levels.
