10. Gray Noise for Sleep – 8 Hours

This 8-hour gray noise track is designed to support deep, uninterrupted sleep. Gray noise is balanced to the way the human ear naturally hears sound, creating a smooth and even noise that feels softer and less harsh than white noise.

The audio remains continuous for the full duration, with no breaks, no volume shifts, and no tonal changes. Ideal for sleeping through the night, relaxation, focus, studying, and masking background noise in a calm, neutral way.

For best results, play at a low, comfortable volume and allow the sound to fade into the background.
