Welcome to the HomeLab Minute. Today we’re tackling one of the biggest nuisances in a home server setup: noise leaking through your door. On Reddit’s r/homelab, one user asked simply, “Soundproof door?” and the community jumped in. The top advice? “Hollow-core doors are your enemy,” as one commenter put it. Swap it out for a solid-core door, rated for mass. Next, seal every gap. Use acoustic door gaskets around the frame, and add a door sweep at the bottom—“90 percent of sound escapes through cracks,” someone warned. Inside the door cavity, layer in mass-loaded vinyl or dense insulation like Owens Corning 703. If you still hear a hum, hang a soundproof blanket on the inside face; it’s a quick, removable fix. Finally, seal around the jamb with acoustic caulk. Follow these steps and you’ll turn down the volume on server noise without sacrificing airflow. That’s your one-minute homelab hack—happy quiet building!
