"dropped ceiling"の定義と意味

What is a "dropped ceiling"?

A dropped ceiling is a ceiling design that is installed below the main ceiling, creating a space between the two. This design features a grid system that holds lightweight panels, which can be easily removed for access to plumbing, electrical wiring, or heating and cooling systems above. Dropped ceilings are commonly used in commercial buildings, offices, and basements, as they provide a practical solution for concealing utilities while improving aesthetics. They can also help with sound insulation and can be finished in various styles and colors to match the overall décor of the space.
