Resilient channels in drywall are used primarily to achieve what?

• A. Decrease Sound Transmission In Walls And Partitions
• B. Accommodate Irregular Wall Surfaces
• C. Provide Decorative Edge Around Openings
• D. Increase Fastener Density At Edges

Answer: (A)

Resilient channels are used to reduce how much sound travels through walls by decoupling the drywall from the structural framing. By mounting the drywall on channels that sit apart from the studs, an air gap and damping effect are created, which slows and weakens vibration as sound moves through the wall. This decoupled assembly lowers both airborne and impact noise transmission between rooms, improving sound isolation. They aren’t meant to fix irregular wall surfaces, provide decorative edges, or increase fastener density at the edges. Those aren’t the functions of resilient channels.
