Ambient sound

Deep, low-weighted brown noise

The deepest, warmest noise we make. Brown noise puts most of its energy in the low frequencies, so it sounds like a soft, distant roar rather than a sharp hiss. Many people find it easier to sit with for hours than white noise, and it's built live so it can run as long as you need.

Tap Brown to hear it, then layer in anything else. Or start from a mix below.

The difference between the noises is the balance of frequencies. White noise spreads energy evenly, which makes it bright and a little harsh. Pink noise rolls off the highs for a warmer, more natural sound. Brown noise rolls them off further still, pushing energy into the bass so the result is deep, smooth, and easy on the ears.

That low-weighted quality is why brown noise has a following for focus, including among people with ADHD. It masks distracting sounds with a steady, non-fatiguing floor, giving your attention fewer things to catch on. Many also use it to fall asleep or to soften the ringing of tinnitus.

Here it's synthesized live rather than streamed from a file. There's no loop point, nothing to buffer, and it works offline, so you can leave it running through a whole workday or a full night without a seam or a pause.

Questions

What's the difference between brown noise and white noise?

White noise has equal energy across all frequencies, so it sounds bright and hissy. Brown noise puts far more energy in the low end, so it sounds deep and soft, like a distant roar. Pink noise sits between the two.

Is brown noise good for sleep?

Many people find it helps. Its deep, low-frequency sound is smooth and non-fatiguing, which makes it easy to relax into and effective at masking noises that would otherwise wake you.

Does brown noise help with focus and ADHD?

A lot of people say it does, especially for ADHD. The steady low-frequency floor masks distractions and gives your attention less to latch onto, though responses vary from person to person.

Can brown noise help with tinnitus?

Some people use it to mask the ringing of tinnitus, and its deep, even sound can make the ringing less noticeable. It isn't a cure, but many find it brings relief while it's playing.
