Gray noise - balanced sound, tuned to the human ear
Gray noise is shaped so it sounds equally loud across the spectrum to human ears, rather than being flat on paper. The result is a remarkably even, neutral sound that many people find the most balanced masker of all.
What is gray noise?
Our ears aren't equally sensitive to every frequency, so 'flat' white noise can sound brighter than it measures. Gray noise applies a psychoacoustic curve so it feels even to you - no frequency jumps out.
For people who find white noise too bright and brown too dark, gray often lands in the sweet spot: full, neutral masking that's easy to listen to for hours.
