What is deep brown noise?

Deep brown noise is brown noise with the lowest frequencies lifted further, so it sounds even darker: more rumble, almost no hiss. It is the sound many people ask for when brown noise still sounds too bright.

How Hush Machine makes it

Hush Machine takes its live brown noise and adds a low shelf filter, which boosts the bottom of the spectrum. It sits at the dark end of the dial.

How people use it

  • A rumble like a train cabin or a ship's engine room, without any rhythm.
  • Masking very low sounds.
  • The darkest point on the dial for people who find every other colour too bright.

Questions

Is deep brown noise a standard term?
Not a formal one. It is the name used for brown noise with extra low end; in Hush Machine it is the far end of the dial.
Will deep brown noise sound right on a phone speaker?
Phone speakers can't play the lowest frequencies, so it sounds best through headphones or a speaker with real bass.
