The test is performed by playing white noise through speakers at a high level on one side of a wall. The STC of a floorceiling or wall structure is a measure of the decibel difference between the airborne sound energy striking one side of the structure and the sound energy radiated into a receiving room on the other side.
STC measures ambient airborne sounds such as talking electronics etc. This rating can be 12311.
