WebSTC stands for Sound Transmission Class and is a rating of how well a structure reduces the transmission of airborne sound (also known as attenuation). The higher the STC, the better the barrier is against sound. When STC is talked about, it is mostly related to doors, walls, ceilings and windows. WebJan 12, 2024 · The NRC rating is a mathematical coefficient that should only have a range of 0.0 to 1.0. A 0.0 rating might be used to describe a smooth-finish concrete wall that totally absorbs sound. A 1.0 rating may be compared to an open window, in which all sound travels through the gap and is not bounced back into space.
