1.
Cut your wooden planks to size for your wall. The 2 x 4-inch planks are cut to the height of your room. The 2 x 6-inch planks will be used as the top and bottom tiles of the wall. Cut the 2 x 6 planks into a size that creates useful frame sections. The more sections and separation, the more soundproof the finished wall will be.
2.
Build your frame by nailing the 2 x 4 planks along a 2 x 6 baseboard in a staggered pattern. The pattern should alternate to the left and right, with the first 2 x 4 nailed to the left edge, the second 2 x 4 nailed to the right edge and so on. Since both sides of the plaster are hung on separate bounces, there will be no direct way for the sound to move through the wall, effective sound insulation of the structure. Finish the frame with a 2 x 6 top plate.
3.
Hose insulation in large pieces around the knots instead of cutting the insulation so that it fits in each part of the wall’s frame. Since the frame plates are thinner than the base plate, there should be plenty of space to work the insulation through the frame. The insulation further insulates the handlebars from noise and vibration.
4.
Hang the drywall on the first side of the wall with screws. Attach the plaster only to the boards in coil with the side of the frame covered. Use as few screws as possible to hold the plaster in place and do not attach the plasterboard tightly to the frame. Use construction adhesives to strengthen the plasterboard’s bond to the frame without providing redundant sound paths through screws. Make sure that the wall does not fit too nicely, so that a buffer can cut vibrations. Repeat this process for the other side of the wall.
5.
Use caulk to fill any gaps between the plaster and the frame. Caulk will not only seal the wall, but will also provide a cushion to absorb sound waves.
Tips and warnings
Whether you have a home-based studio or build a professional workspace, soundproofing your recording environment has several benefits that help produce high-quality recordings. Soundproof walls allow drums, electric guitars and other higher instruments to be monitored from a control room on lower levels with minimal noise. Conversely, well-soundproof walls will prevent external sounds from entering quieter moods and string performances. Most importantly, sound insulation cuts down on sound coming from your studio, so you can record without disturbing neighbors. With the right tools and some basic carpentry skills, you will be able to build your own soundproof walls.
