The Sound of Floors

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.
