Washing Machine Sounds Black Screen 10 Hours | Blackout Sleep Lab

Drift into deep, uninterrupted sleep with 10 hours of steady washing machine sounds on a true black screen. This smooth, low-frequency mechanical hum creates a calming, consistent rhythm that helps block distractions, mask tinnitus, and quiet the mind for better rest. Perfect for sleeping, studying, working, anxiety relief, meditation, and focus. The black screen prevents light stimulation, making it ideal for overnight use and long listening sessions. 🎧 Best enjoyed with speakers or headphones at low volume. 🌙 No music. No interruptions. Just pure mechanical ambience.
