Low Hum Factory Floor
10 Hours of Industrial Machine Frequency for Deep Sleep

Step inside the hushed floor of a vast factory at night. Enormous machines run at steady duty — compressors, ventilation fans, pressure vessels — producing a deep mid-low hum that fills the entire hall as a single unified tone.
No conveyor thuds, no voices, no alarms. The hum is layered and full-spectrum, carrying a faint electrical shimmer on top and a heavy industrial weight underneath.
Ten unbroken hours of constant machine frequency. The dense mid-bass body is engineered to mask street traffic, barking dogs, upstairs footsteps, and muffled conversation through shared walls, while the high-mid shimmer softens the texture so it never feels harsh.
Perfect for apartment dwellers in noisy buildings, shift workers sleeping through the day, travelers in unfamiliar rooms, industrial atmosphere enthusiasts, and anyone who finds pure brown noise too thin. Loud enough to matter, smooth enough to sleep through. Play it at the volume of a wall, not a whisper, and let the factory floor hold the noise floor all night long.
