Brown noise

Brown noise is a deep, soft rumble, like a distant waterfall or the inside of a plane. Press play to hear it, and move the rain slider up if you want rain on top.

It is louder in the low notes and quieter in the high ones than white noise, which is why many people find it less harsh.

Questions

What is brown noise?
Random noise whose power falls as the pitch rises: each step up an octave is about 6 dB quieter. That puts most of its energy in the low end, so it sounds like a rumble rather than a hiss. Source: Wikipedia: Colors of noise.
Why is it called brown?
Not because of the colour. It is named after Brownian motion, the random jiggling of particles described by the botanist Robert Brown, because the signal wanders in the same way. Source: Wikipedia: Colors of noise.
Brown, pink or white noise: which is best?
It is personal. White noise is bright and hissy, pink is softer, brown is the deepest. Try each with the buttons in the mixer and keep the one you can forget about.
Is it free?
Yes, for now everything is free, the real recordings included. There is nothing to sign up for, nothing to install and no ads. Later some real recordings may move to a paid option; the sounds made in your browser will stay free.
