It depends on the size of the room and the type of ceiling you choose. For a room that is 10'x10', the average cost to install an acoustical ceiling is $1,500 - $2,000. There are three types of ceilings: drywall, acoustical, and drop. The most common type of ceiling is drywall. It's cheapest and easiest to install, but it doesn't absorb noise as well as acoustical ceilings. Acoustical ceilings are more expensive to install but they're better at absorbing noise. Drop ceilings are a type of acoustical ceiling that come in panels. They're easy to install and they're also good at absorbing noise.

It depends on the size of the project, but typically it costs anywhere from $2 to $6 per square foot.
