Jan 12, 2021 · Sound Transmission Class or STC is the rating system by which the ability of a partition to attenuate, (reduce the effect of) airborne sound is measured. Materials are tested over multiple sound frequencies, from bass levels of 125Hz to treble levels of 4000Hz. They are then assigned STC ratings , a United States standard since 1961. The STC is a single number rating scale that measures a wall, ceiling, or floor assembly’s ability to block sound transmission.
