Acoustical Testing

Accurate, independent third party testing is critical to meet the regulatory requirements of green construction codes for all types of buildings. At U.S. Rubber we take the growing concern regarding the effect sound has on human performance and living conditions seriously.

Impact insulation class (IIC) is an integer-number rating of how well a building floor attenuates impact sounds, such as footsteps.  A higher number means more attenuation. One should note, however, that all IIC ratings are not equal.  When comparing the acoustical performance of QuietSound^® to other acoustical underlayments, it is critical to note the composition of the products (e.g., rubber (resilient), cork (not resilient) or foam (not resilient)) and the subfloor/flooring assembly of the testing.  Unless the test assemblies are identical, it’s an “apples to oranges” comparison that will yield an inaccurate conclusion.

An IIC rating of 50 and above is most common in building code and HOA requirements.

The Delta IIC rating is the best sound rating to consider when comparing the performance of different types of underlayment. It keeps the manufacturers from promoting misleading results obtained by using materials or methods of isolation that the average assembly does not use.  This test is only relevant for concrete subfloors.
