Fire Ratings are assigned to entire floor/ceiling and wall assemblies OITC and STC are almost the same rating system except that OITC is geared for testing lower frequencies. And, contrary to popular belief, STC ratings of materials don’t just add up The Sound Transmission Class (STC) is a single-number rating of a material's or an assembly's ability to resist airborne sound transfer at the frequencies 125-4000 Hz. Provides both STC and IIC ratings above 60 in specific floor-ceiling assemblies, making it a best-in-class solution by reducing sound two times more than the code requires. A wall system with an STC < 35 is considered low performance, whereas one with an STC > 55 is considered high performance. Compare and contrast MgO panel sound- and fire-rated assemblies for multifamily projects.
