How Well Do You Know Partition STC and Ceiling Acoustics?

This week’s quiz is from Sound of silence: Specifying the four roles of acoustic ceilings. When walls don’t go full height, ceiling systems become key players in acoustic performance. But not all acoustic ceilings are created equal—and they’re not always enough. This article breaks down how ceilings interact with partitions to achieve target Sound Transmission Class (STC) ratings, why Ceiling Attenuation Class (CAC) can be misleading on its own, and how to apply recent research and standards to real-world designs. Read on, then take the quiz to test your technical know-how.
