Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound. In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows and exterior wall configurations. Outside the US, the ISO Sound Reduction Index (SRI) is used. The STC rating very roughly reflects the decibel reduction of noise that a partition can provide. The STC is useful for evaluating annoyance due to speech sounds, but not music or m… WebIn practice, STC values are tested in near optimal conditions in a laboratory environment but do provide a comparison point between assemblies. Similar to STC rating, there is also Field Sound Transmission Class (FSTC) and Apparent Sound Transmission Class (ASTC) ratings which are similar to STC but with some key differences. There are many
