Pick a corner for your vocal booth. For the best results, choose an existing corner with outside walls, near your recording equipment. Using outside walls will offer the best existing sound dampening and a solid existing structure from which you can build.
Lay out your corner vocal booth. The size of your corner vocal booth will depend on how you intend to use the booth and how much room you have available. Once you had decided on the size of your booth, sketch out a simple design by hand or on your computer. An example diagram is attached to this article as a guide to aid in the design process.
Purchase construction materials. Spending a little extra money on quality materials will result in a higher quality vocal booth.
Remove existing carpet, tile, wood flooring and any fixtures in the area you intend to use for your new vocal booth.
Frame out the walls of your booth using wood 2 x 4 studs, according to the dimensions outlined in your plans.
Install a pre-hung, interior door as shown on your booth diagram. Make sure that the door can be opened without obstructions and permits easy access.
Using drywall, fiberboard or plywood, cover the outside of the booth and secure with screws.
Insert R11 insulation between the interior wall studs. Make sure the insulation has the paper side facing the installer.
Using drywall, fiberboard or plywood, cover the interior of the vocal booth frame and secure with screws.
Drill access holes for signal cables and install all necessary cables before moving on.
Drill access holes for an extension power cord or have an electrician install power outlets.
To dampen sound transfer between the vocal booth and the studio, fill any gaps between the wall and floor, the wall and ceiling, booth wall and existing walls, as well as the holes for signal and power cables, using silicone caulk or triple-expanding spray.
To dampen sound transfer through the door, install compression weather stripping and threshold seal to the pre-hung door. Allow any glued stripping to dry completely before verifying that all openings are sealed and the door operates correctly.
Test power and signal cables for correct operation.
Further customize the vocal booth by added acoustical tiles to adjust the sound.
