Like a few others here, I too am taking on a new basement related project and could use some good advice. In a nutshell, I already have a finished basement with my home theater setup, but some of that room is needed for a play area for my three daughters. My wife suggested we section off the basement into two areas: play area and a home theater area. Though the size of my HT may be getting smaller, I am excited about the possibility of creating a "better" room acousticly. My main concern right now is travel of sound through the ceiling tiles: my wife complains that she can hear the movie sounds through the floor of the family room, which is directly over the home theater area of the basement. Can anyone advise me on the best way to prevent the sound of traveling up through the floors? Most of the work will be done by a contractor, so don't worry about the complexity of the solution. Thanks for your help in advance!!
