Violet Noise
Violet noise is the brightest of the standard noise colours: its power climbs about 6 decibels per octave, so nearly all of what you hear sits in the top of the range as a thin, airy hiss. Your browser generates it live rather than streaming a file. Suits listeners who want the sharpest available texture.

Where violet sits among the noise colours
The colours describe spectral slope and nothing more. Pink noise falls about 3 decibels per octave and brown falls about 6; white is flat; blue rises about 3 and violet rises about 6, making it the exact counterpart of brown noise at the opposite end of the range. In practice that means violet has almost no low-frequency content at all, and what body other colours get from the bass is simply absent. Some listeners find that clean and precise; others find it thin or tiring within a few minutes. Both reactions are ordinary and the only way to know which is yours is to try it briefly.
Because the browser generates it live rather than streaming it, no loop point appears and no file downloads: the signal simply continues for as long as the player runs. The same is true of blue noise, green noise and the other synthesised colours here.
Listening to it comfortably
Start lower than you think you need. High-frequency sound can feel light while still becoming fatiguing, and violet concentrates more energy up there than any other colour on this site. Reproduction also varies more at the top of the range than anywhere else: small speakers, headphones and personal hearing all differ, so violet will not sound the same on two devices. Do not use it to overpower loud equipment, and stop if it feels sharp.
Alone it is stark, so a warmer layer underneath usually helps. Compare it directly with blue noise and white noise at matched levels, read the complete guide to noise colors for the full set, or open the violet and brown noise blend in the free sound mixer to put a floor under the hiss.
Frequently asked questions
What does violet noise sound like?
A thin, airy, high-pitched hiss. It is brighter than blue noise and much brighter than white, pink or brown.
How is violet noise different from blue noise?
Both rise with frequency, but violet rises about twice as steeply, roughly 6 decibels per octave against blue’s 3, so it puts even more emphasis on the top of the range.
Does violet noise download or generate?
Your browser generates it live, like the other noise colours here. There is no audio file and no loop point to notice.
Should I use violet noise for sleep?
Most people who use noise overnight prefer warmer pink or brown spectra. That is preference rather than a rule, but keep the level low and stop if the treble feels sharp.
