Acoustic ceiling tiles create a soundproof ceiling. The method you choose will depend on whether you are in a single-story building that has no rooms above the ceiling, or whether there is a room above the ceiling. Here's your guide to types of acoustic ceilings and how effective they are.

Floating Soundproof Acoustic Ceiling Tile

You can use resilient bars to construct a new ceiling under the existing one. You will need to use plaster board with the acoustic ceiling tile to dampen the sound. You could remove the existing ceiling and fill it with acoustic wool if you prefer.

You need to place one layer of plaster board on the bars, then fasten it with screws. Layer it with a soundproofing membrane, then attach the second layer of acoustic ceiling tiles. Seal the soundproof ceiling by leaving a ½-inch gap between the plasterboard and the adjoining wall. Use an acoustic sealant to seal. Doing so will make it airtight and the soundproof ceiling will float.

A Dropped Soundproof Acoustic Ceiling Tile

Drop the soundproof ceiling from the current one with battens that run perpendicular to the ceiling joints. Fill the gaps between with acoustic mineral wool. Repeat again on the floating soundproof ceiling.

Acoustic Ceiling Tile Noise Reduction Capabilities

How well an acoustic ceiling tile deadens sound will depend on the noise reduction capabilities of the materials you choose to work with. These acoustical properties are measured with the Ceiling Attenuation Class (CAC) and the Noise Reduction Coefficient (NRC).

The CAC measures how well the acoustical tile blocks the transmission of sound through the tile. The highest quality tiles offer a CAC rating in the 40 to 44 range. Tiles are available that offer NRC ratings up to 80 percent.

Acoustic Ceiling Tile Summary

Standalone acoustic ceiling tiles can be installed as well. It will block sound transmission between rooms. It also hides wires and pipes.

Not so long ago, if you wanted soundproofing, you were limited to the plain styles that were found at schools or in malls. There are now a variety of styles and colors that offer a wide range of choice that wasn’t available before.

You can choose from traditional textures such as slate, swirls, corduroy, and stucco to elaborate decorative patterns, which makes the use of acoustic ceiling tile much more appealing.
