White noise is a sound that contains every audible frequency played simultaneously at equal intensity — like all colours of light combined into white. Because it covers the entire frequency spectrum, it creates a consistent acoustic "blanket" that masks disruptive sounds around you. This makes white noise one of the most effective tools for improving focus, blocking distractions, and falling asleep in noisy environments.
Your brain is wired to notice change, not constant sound. Every time a colleague talks, a car passes, or a door slams, your auditory cortex fires an involuntary "orienting response" — pulling your attention away from what you were doing. Regaining full focus after each interruption takes 3 to 23 minutes.
Broadband noise — white, brown, or pink — raises your ambient noise floor so these transient sounds no longer stand out. Your brain stops trying to process them. Unlike music with lyrics, pure noise doesn't compete with verbal working memory, making it ideal for reading, writing, coding, and studying.
A landmark 2012 study in the Journal of Consumer Research found that moderate ambient noise (around 70 dB) consistently outperformed both silence and loud noise for creative and analytical tasks.
Try Brown Noise or Coffee Shop. Both mask office chatter while keeping your brain gently engaged. Brown noise is especially popular for ADHD focus.
Pink Noise has been shown in clinical studies to improve slow-wave sleep quality. Use the Sleep Timer to fade out automatically after 60 or 90 minutes.
White Noise is the most-researched infant sleep sound — it mimics the womb. 80% of newborns fall asleep within 5 minutes with white noise. Safe volume guide →
Equal energy at every frequency — a flat, even hiss. The most complete masking sound. Best for general noise blocking, open offices, and infant sleep. Sounds like a fan or TV static.
Play white noise →Deep bass-heavy rumble with high frequencies rolled off steeply. Feels warm and immersive — like a waterfall or strong wind. Extremely popular for ADHD focus and anxiety. Many people find it quiets mental chatter.
Brown noise for ADHD →Balanced between white and brown — each octave carries equal energy, matching how human hearing works. Sounds like steady rainfall. Proven in clinical studies to enhance deep sleep and next-day memory.
Pink noise for sleep →Psychoacoustically calibrated to sound equally loud at every frequency to the human ear. Often described as the most "neutral" noise — not too bright, not too dark. Ideal for tinnitus relief and long listening sessions.
