Flooring Sound Test

Sound absorption of floor coverings may be measured on two of those scales.

Flooring sound test.

Iic is measured in terms of sound impact or how well sound vibration travels through a floor to the room below. Iic and stc tests are conducted in sound test laboratories. The results of the test are rated in terms of the impact insulation class iic. The impact sound insulation properties of a floor ceiling structure including the flooring are usually tested by measuring the transmitted sound in a room below while a standard hammer machine bangs on the floor above.

It all begins with how sound is generated and the medium it transfers through. The main test done by flooring industry is the impact insulation class iic ad sound transmission class stc. The higher the number the better the sound isolation. Sound transmission class stc is an integer rating of how well a building partition attenuates airborne sound in the usa it is widely used to rate interior partitions ceilings and floors doors windows and exterior wall configurations see astm international classification e413 and e90.

The third covers room to room transmission more appropriate for walls. It is important to understand that iic and stc tests are not for individual components of a flooring assembly but for the whole floor ceiling structure from the surface of the floor covering material in the upper unit all the way to the ceiling in the unit below. Iic impact insulation class iic measures a floor ceiling assembly s resistance to the transmission of structure borne or impact noise.
