Impact Insulation Class (IIC): Transmission of impact noise can be controlled by isolation. The ratings are greatly improved by
using cork underlayment. The higher the IIC number the better the impact insulation.
Sound Transmission Class (STC): Measure of resistance of a building element such as a floor or wall to the passage of audible
sounds. The higher the STC number the better the sound barrier .
