Thanks for the advice. It make sense. I'm not sure of a HD link, because I checked the tiles out in the store. I'll let you know.
They won't block any sound from going upstairs, but they will absorb some echo within the room. Tiles that are built and used to block sound are REALLY expensive and there are a few ways to use locally products to get close to the same performance. I always tell people that a drop ceiling is more of a visual barrier than a noise barrier, but if you back the tiles with rock, you increase the density of the floor/ceiling assembly and stop at least some sound.
Do you have a link to the HD or Lowe's tiles? I'll give you some feedback if I can.
