There are two basic style of acoustic ceiling tiles. The first are suspended from, the second permanently affixed to the rafters or floor joists of the room above. The purpose of acoustic tiles is primarily to prevent the sounds in one room from going through the walls into another but also to reduce echoes in mostly empty rooms. Of the two, dropped ceiling tiles are more versatile and easier to maintain.
Drawbacks of Acoustic Tiles
Most acoustic ceiling tiles are made from a pressed fiber that is able to absorb sound waves. Because it is not a single, solid material, it tends to be somewhat soft and is easily scratched or stained. Acoustic tiles may be able to resist moisture in the form of humidity, but aren't waterproof, and so even a small leak could destroy a tile quickly. Replacing a suspended tile only takes a few moments, though, whereas replacing a glued tile could take up to an hour.
Acoustic Tiles Come in Large Varieties
Both permanent and drop ceiling tiles can be purchased in standard design patterns or in special designer styles that have printed faces, embossed figures, or intricate designs. Creative interior designers can change the whole personality of a room by altering the tiles or pattern of the ceiling.
