STC Rating: 73
The term STC refers to the single figure of evaluation used to quantify the transmission of airborne sounds through building elements such as a wall or floor systems. These types of sounds would be the equivalent of voices music radio or television audio in the context of a multi-family building. The term STC translates to Sound Transmission Class and is measured and stated in accordance ASTM Standard number C634 and tested via the test methodology of ASTM Test Methods E 90 E 336 and E 596. When done in an accredited test laboratory these values are stated as a number to the right of the initials STC. When done in the "Field" using ASTM Method E 336 these values are designated by the initials FSTC to the left of the numeric value.

IIC Rating: 70
The term IIC refers to the statistical measurement standards used to quantify the transmission of impact sound energy through a floor/ceiling assembly system. These types of sounds would be the equivalent of foot traffic dropped articles or furniture moving in the context of a multi-family building.

When done in an accredited test laboratory these values are stated as a number to the right of the initials IIC. When done in the "Field" using ASTM Method E-1007 these values are designated by the initials FIIC to the left of the numeric value.IIC values are not heavily influenced by the presence of solid mass in the structure. IIC values are dependent on the presence of a resilient material somewhere in the assembly to isolate and absorb the sonic energy created by impacts.
