Why brown noise?

Brown noise emphasizes lower frequencies, so it sounds deeper and warmer than white noise. Many people find it easier on the ears for long sessions and useful for masking distracting sounds.

Good for

  • Falling asleep and staying asleep
  • Studying, reading, or deep work
  • Masking office noise, neighbors, or other distractions
