My master bedroom is above the family room and the soundproofing is so bad that one can hear a can being opened in the kitchen when in the bedroom. We plan to replace the carpet in the bedroom soon, is there anything that can be done at this time.
Answer:
I've had a lot of success with the following: Sound proofing a wall or ceiling, I've found, is best done by creating a sandwich with lots of bulk. I apply 5/8" gypsum board (roughly taped, jointed and sanded) to the studs or joists and then 7/8" sound absorbing fibrous panel manufactured for the purpose. On top of that, I apply resilient channel 16" O.C. and then another layer of 5/8" gypsum board. This time the gypsum board is properly taped jointed and sanded.
