WitrynaAn impact insulation class (IIC) is a standard rating of how well a building partition blocks impact sound or structure-borne noise. The test to determine the IIC rating of a partition evaluates and quantifies a partition’s resistance to the transmission of impact-generated vibrations from noise source to the receiving side of the partition. WitrynaImpact Insulation Class (IIC) is an acoustical rating used to quantify impact sound absorption and vibration isolation of floor and ceiling assemblies to des...
