Acoustic Drop Ceiling Tile

[Todd Dodds]

I have a large finshed basement with concrete floor, carpeted, and the ceiling is the dropped 24" tile, which is usually referred to as "acoustic".
I have no idea if that's a good thing or a bad thing, and would appreciate some education.

I also have a boxed in support post, right smack in the middle of the room. But that's something I'll take care of when I get good and drunk, and locate my 30' tow chain.

It is only meant to block normal volume talking not music.

Gotcha, but what I'm wondering is if it's more absorbtive or reflective, and does it have a good, neutral, or bad effect on listening room acoustics?

Owens Corning Sandrift tiles are 70 NRC (absorb 70% of sound that hits them). So, they are absorbative, not reflective. To Botrytis's point, that 70% is likely not spread evenly across the audible frequencies but still, its alot better than drywall..... I put it over drywall in den remodel but the project is not complete so I can't testify to its effectiveness. Sure is alot less echo with it than before tho....
