BAP Acoustics has performed hundreds of impact insulation class (IIC) tests across Western Canada. For these test, we utilize a “tapping machine” which you can see in the video below.
The Impact Insulation Class (IIC) rating of a floor system is determined from noise levels measured in the receiving room, typically below the test floor.
Below you can listen to the sound of the tapping machine as recorded in a receiving room while on different floor assemblies.
