This page is about how I built my vocal recording booth. In 1998 the costs were at 2.000 DM (1.000,- €).
The isolation is very good. If you sing inside the booth you'll hear it very low on the outside. Behind the studio door outside the room you will hear nothing. Behind a wall you will hear less nothing. We use this booth to record day and night.
As you can see here, we are moved and now have a separate recording room. So please don't ask for any further photos. But if you have any other questions feel free to ask.
To soundproof the booth from the floor some plies of fibreglass blankets wrapped in drapery and sewed are putted under the booth.
The booth is made of 2cm thick particle boards and is mounted as shown in the picture. The base plate, the roof plate und the four wood strip are the skeletal structure of the booth. The side plates are drilled to the wood stripes.
All splices are filled with silicon.
The front has a rectangular cut-out. A pane was glued on each side, as a window. The panes are 5 cm wider than the cut-out to have enough space for the glue.
Before glueing the windows a wood strip was drilled on each side below the pane to hold the pane until the glueing was complete. After that this wood stripes can be demounted.
Watch out that the panes are completly clean on the inside before gluing. After the glue is dried, it's to late for cleaning!
The door is located on the right side. The door is mounted by hinges. On the other side of the door magnets are mounted to keep the door closed. There are also handles on each side of the door for opening and closing.
The door was sealed with Fenstermoll. One strip was glued to the door, one to the booth, but with a little distance. Therefore the door is isolated double. When you mount the hinges you have to assure the the door closes plane.
Then the outer wall was cemented with Rockwoll Planarock for acoustic insulation.
The inner wall was glued with Illbruck Illsonic Pyramide to make the inside anechoic. A cheaper alternative will be this: www.schaumstoff.com. It should be used at least 10cm height, to have frequencies below 250Hz damped. If you use cardioid microphones this is more than enough.
A little area was left blank to have a terminal for the power, the headphone and the microphon jacks. The opposite side of the terminal was filled with silicon.
It was actually planed to build-in a ventilation system. But that was not necessary at all.
