Frequently Asked Questions
What is white noise and why does it help you sleep?▼
White noise contains all frequencies at equal intensity, creating a consistent 'shh' sound. It masks sudden noises (traffic, snoring, neighbors) that can wake you, and gives your brain a steady signal to focus on, reducing racing thoughts.
Is it safe to sleep with white noise all night?▼
Yes, sleeping with white noise is generally safe. Keep volume moderate (50-65 decibels). Avoid placing speakers directly next to your head, especially for infants.
