THX has more uses then just making a starship battle sound awesome you know. That’s why THX has partnered with Serious Materials to develop some new sound proof doors. The QuietHome soundproof doors are the 2 1/4-inch thick THX-certified doors that claim to be a full 85% acoustical improvement over any other sound proof doors.
How does it work? QuietHome Doors incorporate Serious’ proprietary viscoelastic polymer-based constrained layer damped system, a multi-layer design and advanced seals throughout the door edge. The doors are made up of stainable wood, and come in a pre-hung door package. You wouldn’t want to just replace your front door with it. Well, maybe you would if you are super loud. Your neighbors would appreciate it. But it’s designed for high-end home theaters, commercial studios, offices and conference rooms etc. The doors will cost you $2,500 and will block out so much sound your neighbors will think the place is vacant.
