Black noise
Updated 22 October 2026
Black noise has two meanings. Some people use it for silence, or noise so sparse it is nearly silence. Sound apps use it for a noise even darker than brown, with almost nothing above a low rumble. The mix here is the second kind: a deep, soft roar like a distant engine room.

How to set it up
- Use headphones or a speaker with real bass. On a phone speaker, black noise sounds almost silent.
- Press Play on Black noise.
- If it feels too empty, move to Brown, or raise the 500 and 1k sliders a little.
Black noise for sleep
Some people find even brown noise too bright at night. Black noise keeps only the lowest part, which can cover traffic rumble and the bass from next door while staying very soft on the ears.
Silence as black noise
In engineering, black noise sometimes means a spectrum that is mostly zero. For sleep, true silence is ideal if your room is quiet. If it is not, some noise is usually better than none.
