Auralex has provided raw materials and even complimentary guidelines for wall construction for sound isolation with our Acoustics101 guide for many years. Now we offer yet another piece for reducing room-to-room sound transmission – the Auralex StudioDoor. Both doors are built using a proprietary core stack-up of materials, and StudioDoor 48 includes Auralex SheetBlok Sound Barrier for additional isolation. The StudioDoor is the perfect finishing touch to your acoustically isolated studio. Both doors are wood-based, delivered pre-hung, and ready to finish. Both offer exceptional STC ratings of 41 (StudioDoor41) and 48 (StudioDoor48) and are available in these versions: Left hand Inside, Left hand Outside, Right hand Inside, and Right hand Outside.
