Brown Noise Black Screen 10 Hours | Deep Sleep, Focus, ADHD Relief

Deep, smooth brown noise on a pure black screen. No hiss, no visuals, no interruptions: just 10 unbroken hours of low rumble that masks the world so your mind can settle. Great for deep sleep, ADHD focus, tinnitus relief, and calming restless newborns. The black screen protects your eyes and your battery overnight. The audio fades in gently at the start and fades out at the end, and the volume is mastered to the same level as every Drifthaven video, so you can switch sounds without touching your device. 🐈 Subscribe for new sleep sounds and cozy ambience worlds every week. 🕯️ Every sound on Drifthaven is crafted end-to-end in my studio. This one was synthesized from scratch on my own hardware, no samples, no cloud services. Made with care, one sound at a time. Audio: original, generated and mastered locally at Drifthaven. #blackscreen #sleepsounds #10hours
