White Noise FAQ
What is the difference between white, pink and brown noise?
White noise has equal energy across frequencies (bright hiss). Pink noise softens high frequencies (balanced, like steady rain). Brown noise emphasizes low frequencies (deep rumble, like a waterfall).
Does white noise help with sleep?
Many people find steady background noise masks sudden sounds that wake them up. Try brown or pink noise for sleep — they sound warmer and less harsh than white noise.
Can I use this while working?
Yes. White or pink noise at low volume helps many people focus by covering distracting background chatter. Keep the volume moderate.
