The key difference

Green noise concentrates its energy in the middle of the spectrum, around the frequencies of natural ambience like ocean waves and streams — that is why it is called nature's white noise. Brown noise weights everything to the low end for a deep, warm rumble. Green feels more open and outdoorsy; brown feels deeper and more enveloping.

  • Green noise: mid-focused, nature-like, open and calming.
  • Brown noise: deep, warm rumble; more enveloping.

Which should you choose?

Choose green noise if you love nature sounds and want something soothing and mid-forward. Choose brown noise if you prefer a deep rumble or need to mask low-frequency distractions. Both excel at sleep and relaxation, so let your ears decide.
