They may be used to match impedances in.

. The determining factor is the basic construction of the building in question. The scale like the decibel scale for sound is logarithmicThe IIC is derived from ASTM method E989 which in turn uses a tapping machine specified in ASTM method E492. Sound Transmission Class STC is an integer rating of how well a building partition attenuates airborne soundIn 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.

Transformers for electronic circuits or for low-voltage power supplies are used to match the supply voltage to the operating voltage of components or accessories or to match the impedance of a load to a supply in order to maximize power throughput. The Sound Transmission Class STC is the rating of airborne sound transmission. Impact insulation class or IIC is an integer-number rating of how well a building floor attenuates impact sounds such as footstepsA larger number means more attenuation.
