How to Soundproof a Drop Ceiling

If you want the simplest drop-in upgrade for both sound control and acoustics, replace the existing tiles with BlocknZorbe drop ceiling tiles.

For performance context, absorption is commonly described by an NRC rating, which helps explain how well a tile reduces echo and reverberation inside the room. Blocking performance is commonly discussed using an STC rating, which relates to how well a barrier reduces airborne noise transfer.

If you want to keep the existing ceiling appearance but improve sound control, ceiling tile backers add mass above your current tiles. Our best ceiling tile backer is the CelluZorbe™ HD Ceiling Tile Backer, which is placed above the existing tiles and hidden from view.

These backers can be installed above the tiles you already have or used alongside upgraded acoustic ceiling tile options for improved overall performance, depending on whether the goal is sound blocking, acoustic control, or a combination of both. This is the most direct way to create a more solid “lid” without changing the visible finish.

Alternative: Acoustic Ceiling Tiles

If you’re not dealing with sound leaving or entering the room but rather the quality of the sound in your space, like improving the acoustics in an open office or government building, Second Skin acoustic drop ceiling tiles are a great fit for this need.

Our Timberwool™ wood wool ceiling tiles and PolyZorbe™ polyester ceiling tiles (also PolyZorbe™ vivid polyester ceiling tiles for a colorful flare) provide an upscale look with high absorptive qualities.

We have more information if you want to know more about what acoustic ceiling tiles are.

If the ceiling plenum connects multiple rooms, HVAC paths can carry noise room-to-room or introduce vibration that radiates into the space. In those cases, review our strategies to get a quieter HVAC to help identify where sound is entering or escaping and how to fix it.

You should also look for ceiling penetrations such as drop ceiling lights, which can become weak points in an otherwise treated ceiling. In some situations, adding mass-loaded vinyl backing above these fixtures can help reduce sound leakage by increasing mass where the ceiling assembly is otherwise thin.

If you are planning a more comprehensive ceiling solution, it can also be helpful to review how to create a soundproof ceiling or understand how these challenges appear in a conference room ceiling.
