White, Pink & Brown Noise for Sleep: A Practical Guide

White, pink, and brown noise are labels for different sound textures and frequency balances. They may mask intermittent environmental sounds for some listeners, but preference and context matter more than a claim that one colour of noise works for everyone.

Try the lowest comfortable volume, use a timer, keep important alarms audible, and stop if the sound feels harsh or distracting. A short trial across several nights is more useful than searching for a guaranteed sleep frequency.

The full article discusses masking, personal preference, hearing safety, and when silence is preferable. It is an educational guide, not insomnia treatment.
