White, Pink & Brown Noise

White noise has equal energy at every frequency and sounds like a flat hiss. Pink noise reduces the higher frequencies, making it deeper and gentler — similar to steady rain. Brown noise reduces high frequencies even further for a deep, rumbling sound like distant surf.

Many people find pink and brown noise more soothing for sleep because their deeper tone is less harsh, while white noise is very effective at masking sudden disruptive sounds. The best choice is the one that feels most comfortable to you.

For adults, playing noise at a low, comfortable volume overnight is generally considered safe. Keep the volume moderate and place the source a reasonable distance away. For infants, follow pediatric guidance on volume and duration.

Yes — steady noise can mask distracting background sounds and create a consistent audio environment, which many people find helps with concentration during work or study.
