Violet noisefour versions, measured.
Violet noise is the mirror image of brown. Its power rises by about 6 dB each time the frequency doubles, so the highest pitches carry the most energy. Blue noise is its gentler relative, rising by about 3 dB. Both sound thin, airy and sharp, like steam or a fine spray.

What violet noise is
Hush keeps its brightest noises in this group. Violet static and Blue static climb steeply, while Mist static and Ivory noise stay close to level across the upper range.
Across the group, the level between 2 and 12 kHz rises 3.0 dB per octave on average. Mist static is the darkest: it stays about level. Violet static is the brightest: it rises 6.1 dB per octave.
Each is a single steady sound, with no layers to mix.
The four sounds, darkest first
The shape is each sound's level in nine bands from 2 to 12 kHz; tilt is its slope. Negative is darker.

What is the difference between blue noise and violet noise?
Both get stronger towards high frequencies. Blue noise rises by about 3 dB per octave and violet noise by about 6 dB per octave, so violet sounds sharper.
Which violet noise sounds are free in Hush?
None of these four is among Hush's six free sounds. They are part of Hush Plus, and Hush plays a short preview of a Plus sound before you subscribe.
How were these levels measured?
Each sound was measured in one-octave bands centred from 2 to 12 kHz, the range Hush uses for pitch matching. A level is given in decibels relative to that sound's overall level, so it shows the shape of a sound, not how loud it plays. The figures come from Hush 1.0.0 (9).
