   Gilles, two things:

   First, please delete your duplicated post... the other one.

   Second, blown-in cellulose insulation makes for a fairly effective sound-dampener. You won't be able to "sound-proof", but you will sound-dampen. The wall would have to be acoustically islolated for sound proofing (total absence) to occur. Not practical.

   *Hi Gilles,You would have to eleminate all common conections between the two halves.If any of the plumbing, electrical or ductwork goes from one side to the other, soundproofing becomes an exercise in futility.There are several things that you can do to improve the sound attenuation between the two sides.Installing a second insulated wall on the inside of one of the units with a 1" air space between the new and old walls would help a lot.One of the tricks in soundproofing is using a variety of materials with different densities and compositions. You can glue a 1" styrofoam to one side and then glue the drywall to the styrofoam so that no nails or screws penetrate the walls. You can add cork to the wall and then drywall over it, in the same fashion.Sorry I can't be of any more help,Gabe

   *Do a search of the archives, this has been covered several times with several different approaches.

   *You might try U.S. Gypsum's website .......they have literature and techniques for sound reduction.

   Hi,

   I am looking for the best way to sound proof an existing party wall between a semi-detached house. The house was built in 1907 so the walls are composed of plaster and 3" x 4" every foot. I exposed one side already and would like to find the best way to sound proof the house.

   All advice and experience are welcome. Thank you.
   Gilles
