I used a product called Z brackets. As the name implies it is shaped like a Z. It is made of 18ga? metal. It basically de-couples the ceiling from the rafters. I had foam insulation sprayed in between the rafters and also sprayed the air ducts. Seemed to work very good for me, did not make it totally sound proof, but reduced a lot. My wife can now sit and watch TV which is above listening room and only has to turn the TV up a few DB.
There are a lot of new products out there that you need to do research on. It all depends on how much money you have for the project. The Handbook of Acoutical Engineering has some great information in it.
