Frequently Asked Questions

White noise has equal power at all frequencies and sounds harsh and hissy. Pink noise has equal power per octave (more natural sounding, like rain). Brown noise decreases more steeply at high frequencies and sounds deep and rumbly, like a strong wind or ocean waves.

Yes. Brown and pink noise are particularly popular for sleep because their lower-frequency emphasis is soothing. They work by masking intermittent sounds (traffic, voices) that can disrupt sleep, creating a consistent sonic environment.

At moderate volumes, yes. Keep the volume low enough that you can still hold a conversation comfortably. Extended exposure to loud noise of any kind can damage hearing. This tool defaults to 50% volume as a reasonable starting point.
