There are a few ways to fix an acoustic ceiling. The most common way is to affix a metal or wood frame to the existing ceiling and then attach a new acoustic ceiling tile to the frame. Another way is to remove the existing acoustic ceiling tile and replace it with a new one. A third way is to install a new acoustic ceiling directly onto the structure above the existing ceiling.

You can fix an acoustic ceiling in a few different ways: -If it's just water damage, you can use a squeegee to dry the area and then use a sealant to patch up the hole. -If there are cracks in the ceiling, you can use caulk or spackle to fill them in. -If the ceiling is completely collapsed, you will need to repair or replace it.
