In drywall construction, resilient channels are used to accomplish what?

• A. To Decrease Sound Transmission In Walls And Partitions
• B. To Protect Outside Corners From Damage
• C. To Cover Wall Board Edges And Ends For Cosmetic Purposes
• D. To Secure The Tops And Bottoms Of Metal Studs

Answer: (A)

Resilient channels are used to decouple the drywall from the structural framing, creating an air gap that dampens vibration and reduces sound transmission through walls. By mounting the drywall to thin channels that are attached to the studs, the drywall moves more independently from the frame, cutting down on how noise and impact transfer from one side to the other. This is why they’re chosen for improving acoustics in walls and partitions. They aren’t intended for protecting outside corners, cosmetic edge covering, or securing the tops and bottoms of metal studs—those roles are filled by corner beads, edge trim, and framing tracks, respectively.
