What Is Brown Noise?
Brown noise, also called red noise or Brownian noise, has energy that drops by 6 dB per octave. It emphasizes low frequencies, giving a deep, soft rumble. See Brownian noise for the science.
Who Uses It?
Many people with busy minds, ADHD or light sleep find brown noise calming. It masks low-frequency sounds like engines and neighbors better than white noise.
Get the Best Result
Use headphones or a speaker that can reproduce bass. Phone speakers may sound thin, so a better speaker helps. Check low frequencies with the bass test.
Other Noise Types
Try white noise or pink noise if brown sounds too heavy.
