Chroma Noise
Noise masking uses colored noise variants — white, pink, brown, and beyond — to improve focus, mask distractions, and promote relaxation. Our guides explore the science behind each noise color and provide evidence-based recommendations.
What is Chroma Noise?
Colored noise refers to categories of random sound signals defined by their spectral power distribution across frequencies. White noise has equal energy at every frequency, pink noise emphasizes lower frequencies with a 1/f power curve, and brown noise further amplifies bass. Each color masks environmental distractions differently, making them useful for focus, sleep, and tinnitus management.

Frequently asked questions
What is the difference between white, pink, and brown noise?
White noise has equal energy across all frequencies. Pink noise emphasizes lower frequencies, sounding deeper and more natural. Brown noise further boosts bass, resembling heavy rainfall. Studies show pink noise may improve deep sleep by 23% compared to silence.
Which colored noise is best for focus?
Research suggests pink and brown noise are most effective for sustained concentration. A 2021 study found brown noise reduced distraction-related errors by 28% in open-office environments compared to no masking.
Can noise masking help with tinnitus?
Broadband noise, especially white and pink noise, is a frontline tool in tinnitus management. The American Tinnitus Association notes that 60-80% of patients report relief when using personalized noise masking protocols.
