I am in the planning stages of my HT that I am building in my basement. One thing I am still unsure about is what to do about containing the sound in the basement and not hearing it in the MBD, which is directly above it. Besides putting insulation between floor joists, what other options do I have? Is there a specific type of insulation, or should I double up? Walls are going to be double wall, single drywall construction.
