Not perfect but better than the tests you were talking about.doncb wrote:Really, all of the talk about putting several pieces of sheetrock together or even a few inches apart doesn't prove much. To be realistic you need to set up like your home. In my case, the next room that someone might be in is 12', a closet door, clothes and two layers of sheetrock away. To be realistic, a test would need to be set up that way. Worried about the room on the other side? Add 10' and another wall.
