For use under engineered and laminate flooring.

Both tests measure sound transference from an upper level room to a lower level room. The IIC measures sound such as moving furniture and walking, while the STC measures sound such as voices and television. Minimum sound rating required by most building codes and architects is 50. The first two ratings better measure the performance of the installed product while the delta rating more specifically measures just the product's potential sound reduction capabilities
