> 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.

## What it sounds like

Brown noise with more rumble at the bottom.

## 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.
