IIC and STC 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. ∆ Delta Rating is the only true measurement of sound reduction from a product (not a floor assembly).
