Gray Noise for Sensitive Sleepers
Psychoacoustically Flat Sound Perceived as Equal Volume Across All Frequencies

Gray noise is specifically engineered to sound perceptually flat to the human ear, meaning every frequency from the deepest bass to the highest treble is perceived at exactly the same volume. This is different from white noise which is mathematically flat but sounds treble-heavy to our ears or pink noise which compensates but can sound bass-heavy.
Gray noise applies an inverse equal-loudness contour to achieve true perceptual neutrality. The result is the smoothest most balanced noise color possible.
For sensitive sleepers who have tried white, pink, and brown noise without finding the right fit, gray noise often solves the problem immediately. There is nothing to notice, nothing that stands out, just a perfectly uniform sonic blanket that covers everything equally.
This ten-hour recording maintains exact psychoacoustic calibration throughout. No loops, transitions, or volume changes. Ideal for people with hyperacusis, misophonia, sensory processing sensitivity, or anyone who finds other noise colors somehow wrong.
