Resilient channels Some of you might be thinking of installing a suspended (or "floating") ceiling with resilient channels to reduce sound transmission between upstairs and downstairs floors. If you go this route and go to the expense and trouble of demolition and remodeling -- or you're building new construction -- make sure that you affix the channels properly to the wood framing. Improper installation can create a "fail" that continues to allow noise transmission between floors. These illustrations on the UK website "Sound Service" shows a close up of how the resilient channel should be attached to wood floor joists. Attaching them so that they flex away from the wood framing reduces vibration that typically transfers from floor to floor, and this is what's meant by the term "floating." This PDF from Buildsite offers a spec sheet of how to install a resilient channel, but with no illustrations. Added in 2023 : This YouTube video from
