Soundproofing a Recording Studio

 Soundproofing a studio can actually be a fun task once you know how to
approach this project.
 The first order of business is to find a space that will be dedicated to the
studio project. Oft times home studios are constructed in a basement of the
home, however this is not always the case, especially in places like
California, where there are no basements.
 Once you have picked out just the right area for your studio, the next step
is to take measurements of the space and to begin gathering your building
materials. If you are planning on framing the walls with 2' X 4' studs, then
it is always a good idea to stagger the studs. In other words to have one set
of studs that stick out further than the adjoining stud. Basically this would
make it so the the drywall would attach to every other stud and thus the
walls would have less contact points with the structure that would reduce the
sound transmitted through the walls.
 Now a full tilt studio would consist of 6" staggered studs and the wall
cavities would be filled with a rock wool material or the bonded acoustical
cotton batts. The next step would be to apply a layer of 1# mass loaded vinyl
directly to the face of the studs. The MLV is a lead substitute that contains
no lead whatsoever. The MLV would be stapled or nailed to the studs, provided
the studs are wood. If you're utilizing steel studs, then you would need to
use self tapping sheet metal screws.
 Tha MLV would act as a soundproof barrier that would act as a membrane
across the face of the studs. You would over lap all of the seams of the MLV
where ever possible and then caulk the over lap as well as around the
perimeter of the membrane.
 Once the MLV is applied to the studs and sealed, we come to a crossroad. You
have a choice here. Your first option would be to use sound clips and furring
channels in order to float the walls of the studio. The Sound clips and
furring channels is a very effective method of floating the walls so that
they are resilient and also so they are conpletely independent from the
ceiling, the floor and the adjoining walls.
 It would take me a longer time than I have here to campletely explain the
Sound clips system, but suffice it to say, that floating the walls and the
ceiling in your studio is the most effective method from stopping sound from
going in or out of your studio.
 The last step in building your studio walls is to add the drywall to eather
the studs or to the furring channels if you are floating your walls. I always
recommend 5/8:" drywall from US Gypsum or other reputable drywall
manufacturer. You can also use quiet rock in this application, but that will
add dramatically to the cost of your studio. I generally recommend adding 2
layers of 5/8" drywall to your studio walls using a product called Green Glue
the would be sandwiched between the 2 layer of drywall to give the drywall
extra damping capabilities.
 This article covers the basicas of building and soundproofing the walls in
your studio. The same methods work for the ceiling as well. In other articles
we will be talking about floating the floor in your studio, but until then,
thanks for reading about how to build a soundproof recording studio. As
Always, Bob O.
