White noise

White noise is the even hiss of every pitch at once, like a detuned radio or a fan on high. Press play, set the volume low, and add rain if you prefer something softer.

Because it covers the whole range of hearing, white noise is good at hiding speech and sudden sounds. Some people find it sharp; brown and pink noise are gentler.

Questions

What is white noise?
A random signal with the same power at every frequency. Since our ears hear high pitches more keenly, it sounds bright and hissy. Source: Wikipedia: Colors of noise.
Is white noise good for sleep?
Some people sleep better with it because it masks sudden sounds. The scientific evidence so far is limited and rated very low quality. Source: Riedy et al., “Noise as a sleep aid: a systematic review”, Sleep Medicine Reviews, 2021.
What is the difference between white and pink noise?
Pink noise turns the high pitches down, so each octave carries the same energy. It sounds softer, more like steady rain than a hiss. Source: Wikipedia: Colors of noise.
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.
