The Sound Transmission Class (STC) is a single-number rating system based on an 18-point scale that describes how well a building partition attenuates airborne sound. It is an ASTM International standard method of rating indoor partitions and elements for their ability to block sound transmission from one room to another. The STC is also known as ASTM Standard E 413. Read https://www.fb101.com/2020/11/how-to...-as-it-can-be/ article to learn how you can write compelling coursework on this topic. The STC rating is essentially a sound pressure level rating that attempts to measure how much noise passes through a partition.
