10 Hours of Deep Brown Noise | Black Screen for Sleep and Focus

Deep brown noise plays for 10 hours with a full black screen, offering a smooth, steady low-frequency background for sleeping, studying and quiet focus. This companion edition uses the exact same approved brown-noise audio master as the Dark Amber Glow edition. The screen remains fully black for the complete video. There is no rain, thunder, music, voice, tone, beat or environmental sound source. Set the volume to a comfortable level and settle into your own routine. #BrownNoise #BlackScreen #FocusSounds
