What's the difference between white, pink, and brown noise?
White noise has equal energy across all frequencies, giving it a flat, hissy sound. Pink noise reduces higher frequencies, giving a deeper, more balanced sound many people find soothing. Brown noise (also called red noise) reduces high frequencies even further, producing a deep, rumbling sound similar to a waterfall or heavy rain.
What is noise used for?
Background noise is commonly used to mask distracting sounds while working or studying, help with falling asleep, soothe babies, or provide a consistent audio backdrop for meditation and relaxation.
