I will be building a dedicated Home Theatre in our new home and have invested in a double isolation system that will all but eliminate sound passing from the room. It is easiest to think of sound like water. There is little use plugging up some of the holes and leave other areas untreated. The sound will effectively follow the path of least resistance. The soundcheck gyprock works by increased mass. Mass is your friend when trying to stop sound penetrating, but it can only do so much. The best and most effective means is decoupling your wall and also increasing the mass. There are a number of products that can achieve this. In order to decouple your wall, the simplest and easiest way is through using Green Glue Whisper Clips. These screw into the wooden studs of your wall and then a thin hat channel is run on the clips. The gyprock then screws into this hat channel, thus reducing the contact area between the gyprock and your studs. If you remember the old kids telephone of two jam tins and a piece of string, it is much the same concept. Remove the string and the sound no longer carries. By reducing the number of points where the gyprock is attached to your house frame, you will reduce the transference of sound from the room. This will offer a marked improvement. Info on the clips can be found on google. Just do a search on Green Glue Whisper Clips. I paid about 5 bucks per clip and I needed about 250 for a large room (ceiling and 4 walls). For extra soundproofing, I am using double thickness gyprock. Each layer will be about 20mm thick and between each layer is an elastomer product called Green Glue. This sticky, icky material basically absorbs sound energy which travels through the first layer of gyprock and converts the energy to small levels of heat so that it dissipates. All sounds very complicated but its not really and the results are excellent. So, depending on how quiet you want to get, the Batts will offer the minimum level of sound reduction. The higher mass gyprock is better but for the best results, the suggested approach is the double gyprock, green Glue and clips. May add a few grand to the room, but over the life of the home, it is a small price to pay for a good nights sleep. Good luck. Greg Re: Sound check vs sound screen 4Nov 06, 2010 1:30 am Nice summary, Greg. In addition to the clips offering a reduction in contact points (less conduction), the decoupling also immediately lowers the resonance point of the assembly. This is directly related to a better ability to control low frequencies. Ted White Re: Sound check vs sound screen 5Nov 07, 2010 9:52 pm Ted White Nice summary, Greg.
