Frequently Asked Questions

What is the difference between white, pink, and brown noise?
White noise has equal energy per frequency (Hz), so it sounds bright and hissy. Pink noise has equal energy per octave, matching typical hearing and sounding more balanced. Brown noise rolls off further, sounding deep and rumbling.
Can I use this for masking or relaxation?
Yes — many people use pink or brown noise for sound masking, focus, or sleep. This tool generates the noise locally in your browser; it is not a substitute for medical or audiological advice.
