ASTM defines single-number metrics for testing of airborne sound transmission class (STC) and impact isolation class (IIC). The impact measurement method for IIC uses a calibrated tapping machine as the sound source. The impact measurement method for IIC uses a calibrated tapping machine as the sound source.

Impact Insulation Class (IIC) is a single number rating used to evaluate the effectiveness of a floor/ceiling system at reducing both high-frequency and low-frequency impact sound transmission in a laboratory. Conclusion Ultimately, the real purpose of designing for good acoustics is to improve the lives of the people occupying a space.

Floor assemblies for multifamily projects are typically required by International Building Code ( IBC ) Chapter 12 to meet minimum sound ratings of sound transmission class (STC) 50 and impact insulation class (IIC) 50. It is relatively common for building owners to ask for their floor assemblies to be designed to exceed these code minimums.

En route to answering these questions, one must first consider the traditional approach to acoustics, which relies on ‘categorization’ and ‘acceptable-level’ schemes prevalent throughout building standards and codes.

Some hybrid carpets can perform more than 200 percent better than hard surfaces in Impact Insulation Class (IIC) ratings, which measure how well a flooring absorbs impact vibrations within a room and between floors of a building. Today’s hybrid carpet is offered in hundreds of color and pattern combinations, including customizable options.
