Maximum Masking
White noise is the most effective at masking sudden sounds like doors, conversations, or traffic because it covers all frequencies equally.

Why White Noise Works
White noise contains all frequencies at equal intensity, creating the most effective sound masking experience.
Instant Sleep
The consistent, predictable sound helps your brain stop processing environmental changes, allowing you to fall and stay asleep.
Baby-Approved
White noise mimics the whooshing sounds babies heard in the womb, providing comfort and helping newborns settle faster.
Understanding White Noise
The mathematics and physics behind why white noise is so effective.
Equal Power Across All Frequencies
White noise gets its name from white light - just as white light contains all visible colors equally, white noise contains all audible frequencies at equal intensity.
- 20 Hz to 20,000 Hz coverage
- Constant power spectral density
- Named after white light properties
- Most studied noise color in research
Frequently Asked Questions
Is white noise safe for babies?
Yes, white noise is safe for babies when used correctly. Keep the volume below 50 decibels (about the level of a quiet conversation) and place the sound source at least 7 feet from the crib. Never use white noise continuously - turn it off once your baby is asleep or use a timer.
Can white noise damage hearing?
At moderate volumes, white noise is perfectly safe. Keep it at or below 70 decibels (similar to a shower running) for extended use. Our app includes volume recommendations and a timer feature to ensure safe listening.
Why does white noise help with focus?
White noise creates a consistent auditory environment that your brain can easily ignore. This reduces the cognitive load of processing random environmental sounds, freeing up mental resources for the task at hand. It's particularly effective in open offices or noisy environments.
Is white noise or brown noise better for sleep?
It depends on personal preference. White noise is better for masking high-pitched sounds like conversations, while brown noise's deeper frequencies are better for masking low rumbles. Many people find brown noise more soothing, but white noise is more effective at blocking a wider range of sounds. Try both to see what works best for you.
