Hi y'all, I've spent a while foraging and scrounging for some ideas and methods on building a VO isolation booth and I've come up with a basic design. Considering the investment it would take I wanted to post it here so hopefully you good folks could help me catch any major design flaws. In this post I'm just focusing on the main structure and walls, there are of course many additional elements such as ventilation, lighting, equipment connections etc or any internal absorbtion materials that aren't in the diagrams.
The materials I plan to use:
15mm Gyproc Soundbloc - 2 layers on the outer surface of both stud walls and 1 on the inner surface of both.
100mm thick Rockwool RW5
100 x 50mm stud timbers
19mm OSB on floor with a layer of 19mm quiet board
SheetBlok Sound Isolation Barrier )or similar - between floor boards and between outer plaster board.
U-boats on the booth floor joists.
Green glue or similar and/or joist tape for around the studs and where they butt together.
2 x 45mm thick standard firedoors
About the location: unfortunately in my home I'm plagued with flybys from a near by airbase and large trucks so I feel a lot of isolation is required.
The overall structure is basically a booth within a booth using two stud walls separated with a 50mm airgap. Two outer layers of plasterboard, 1 inner and a rubber mat isolation barrier per stud wall and the ceilings. Rockwool to fill the walls.
The floor has 100mm joists using the U-boats and rockwool between the joists and capped with plasterboard also between the joists. On top of that two 19mm OSBs sandwiches a Quietboard and 1 or more layers of the rubber mat isolation barrier. There would also be something used on top of that internal to the booth but I'm not sure which of the many options to choose at the moment.
I hope I've sufficiently shown the intention and I hope there are no major issues, please do let me know if you believe this would achieve the goal and any improvements or corrections that would help.
Thanks for your time and consideration.
