White, pink and brown noise

White noiseHas the same energy at all frequencies, so it sounds like a bright hiss, like a radio between stations. It covers sudden sounds well.
Pink noiseSofter and deeper than white noise, like steady rain or wind. It is the most popular choice to relax, sleep or study.
Brown noiseThe deepest of the three, like a strong waterfall or distant thunder. It has very little treble, so it is the least sharp.
Sleep timer and downloadChoose a timer and the sound fades out by itself. To use it without your browser, download a track of up to 5 minutes and play it on a loop.

Many people use these sounds to cover background noise when they sleep, study or work. They are not a medical treatment. Play them at a low level that does not bother you or hide important sounds around you. Each type plays at a similar loudness, so you can switch between them without changing the volume.
