  • sound proofing

    This isn't studio related but I figured it was close enough. A friend of mine has to sound proof an office because on the other side of the wall is a day care with crying kids. Since I'm a musician, he asked me if I knew of a good way to keep the sound from the kids out of the office. Unfortunately I don't have experience in that area. He was going to build another wall parallel to the exisitng one and put insulation in there. I figured the denser it was the better so my suggestion was to use that thick foam you can get at home depot. Would that work or do you know of a better way to approach this? Thanks.

    Depending on his budget, I would say that he can use resilient channels with 2 sheets of 5/8 sheet rock glued together with green glue, but if he wants to do the double wall thing...

    Leave a 2-4" air gap between walls (VERY IMPORTANT).

    Float the studs with Uboat floaters.

    Insulate with r13

    double 5/8 rock with green glue. If he really wants to do it right, he'd use resilient channels on the spaced studs too. But that's getting crazy imo.

      the denser the material the harder it is for sound waves to pass through it. Concrete is the best so a breeze block wall would be amazing. Using a AIr cavity makes the sound waves lose energy as they pass through different materials say AIR-Wood-air-concrete. It should be also noted to have a perfectly sound proof room would require about 4 feet of concrete to restrict bass frequencies. Sound like most energy's will pass through the easiest point from A-B so even if you have 4 walls a floating floor will allow sound to pass from room to room avoiding the walls. I would go with creating a cavity.

        We're talking about crying kids. I think a wall on resilient channel will do fine. I did the same thing for a video company. Their film show room was adjacent to a film editing room. We built another wall on resilient channels, filled the airspace with pink insulation to stop resonance. And that solved most of the problem, then we found that sound was being transmitted through the floor. I took a skill saw and cut the floor and that solved the problem.

          Depending on his relationship to the other company, he might ask them to put up some 'artistic' sound absorbing boards on their shared wall on their side. I just did this with panels I made myself between two apartment walls and it worked awesome.

          What I used:
          Rigid Foam glued to Soundboard (like cardboard, but compressed saw dust kind - can be crumbled in you hand), all wrapped in a nice fabric that's glued to it and hung on the wall.

          I put 2 of these (2' X 4') in the TV room, who's small wall is up against the bedroom wall, and not only did it reduce the sound in the bedroom, but made the TV room sound better (subjectively of couse).

          Might not work for this application, but it may.

          Good luck.
