Violet Noise

Violet noise — also called purple noise — is the brightest color of all, with energy climbing steeply into the highest frequencies. Press play to hear it instantly.

Its strong treble emphasis makes violet noise a specialist tool: it is used in tinnitus sound therapy to mask high-frequency ringing, and in audio engineering as the opposite of brown noise.

What is violet noise?

Violet noise increases in power by 6 decibels per octave as frequency rises — the steepest treble boost of the noise colors, and the exact mirror of brown noise. The result is a thin, sharp, airy sound dominated by the highest audible frequencies.

It is generated by differentiating white noise, which amplifies the high end. Our engine produces it live so it plays seamlessly.

Uses and benefits of violet noise

Violet noise is a niche but genuinely useful color, especially in hearing health.

  • Tinnitus masking: its high-frequency energy can cover high-pitched ringing, a common tinnitus profile.
  • Sound therapy: sometimes used under professional guidance for tinnitus relief.
  • Audio testing: used to analyze high-frequency behaviour in equipment.

Frequently asked questions

Is violet noise the same as purple noise?

Yes. Violet noise and purple noise are two names for the same sound — the brightest noise color, with energy weighted most heavily toward the highest frequencies.

Can violet noise help with tinnitus?

Violet noise is sometimes used to mask high-pitched tinnitus because its energy sits in the same high-frequency range. It masks rather than cures the ringing. For persistent tinnitus, speak with an audiologist and see our noise for tinnitus guide.
