How To Soundproof Walls: • How To Build A Soundpr...
When I was first thinking about building my own home recording studio I wanted to build it in a pre-fabricated shed. The reason? It is cheaper and easier to just have a shed delivered and then soundproof the inside of it. In theory this is a great plan, but there are two main things we will talk about in this article that make your shed design potentially a disaster.
1) Case Study - Nashville Shed Recording Studio
Currently, my friend and builder, Henry Thompson, is building a soundproof recording studio here in Nashville for a drummer/producer. The studio is a big barn style shed. The goal is to soundproof his pre-fab shed so that he can play drums without bothering his neighbors and produce clients in a professional home recording studio.
2) The Problems With A Shed
This shed was placed on an existing concrete slab in Taylor, the owners, driveway. The company who sells the shed came in and built the full shed in a day or two.
That is an incredible deal, but there are two big problems with using a shed that was built on site.
First, the shed was built with a wood deck floor on top of the concrete driveway.
Second the shed walls or sheathing are very thin. This is part of the reason it is cheaper than traditional building methods, but this is also why it is not ideal for soundproofing. In soundproofing we want mass, and thin walls mean way less mass.
3) So What Are The Solutions?
The first thing you must do is remove the wood deck floor. To do this you must remove the plywood from the floor and cut out all the wood cross bracing on the floor. You must use the concrete slab as your floor for it to be properly soundproofed.
For the the thin walls the key is to add mass to those existing walls. To this I recommend adding two layers of 5/8" drywall to the inside bays of your existing sheathing. To save money, I would have taken the plywood from the original shed floor and cut it down to size to add mass to the outside walls.
Below is a diagram from Home Recording Studio: Build It Like The Pros by Rod Gervais.
Notice in this diagram that he recommends adding two layers of 5/8" drywall with a small gap around the drywall. Fill the small gap with backer rod and acoustic caulk to seal the added drywall to the sheathing. Then you can add a 1" cleat over the backer rod and caulk to ensure the new drywall is fully sealed and airtight.
This method will ensure your outside walls match the mass of your inside walls and is crucial to achieving the STC ratings we need for recording studio design.
Conclusion
You can build a professional recording studio in a pre-fabricated shed, The key is to build it on top of a level concrete slab and to beef up the interior walls and ceilings of your building so that you are starting with an excellent structure. Then when you add the soundproofing techniques on top of that structure you will get professional results.

This is exactly how I want to soundproof my garage! This is the only video I came across that has the idea of double drywalling in between the studs to the outer layer! The only thing I don't get is couldn't I just make the drywall a tighter fit and just use acoustic sealant around the drywall for air tight fit? Also... looking forward to 2nd part and I'll be for sure getting that book! You're videos have been a huge help in my soundproof planning! (Double wall etc!) thank you!!
You can. In this build the contractor used spray foam to make it airtight and provide the necessary construction to properly vent the roof. This makes it so you don’t need soffits under the eaves.
I'm trying to see what my best option would be if I don't put down a concrete slab. I don't have much land that I want to take up with a slab and it would be nice for my drum shed to be portable if I ever move house. I'm planning on a 8'x12' shed, just big enough for drums and someone else to jam with.
interesting idea about adding the drywall directly to the exterior wall (internally), hadn't thought of this, thanks!
Glad it was helpful!
I actually have a 12x28 one I’m doing right now!!
Great
My studio is an 8x9ft spare room. It's like a padded coffin.
Oh man!
Hello! Have you thought about using MDF Instead of plaster for sound proofing? I was thinking of doing the double wall system with 25mm MDF and one layer of plaster on each side!
Cheers
What does the 25mm weight per sqm
@@soundproofyourstudio 22.5kgs. one whole sheet 2.4 x 12 is 56kgs
how much the shed costs? is there any good ones that are $700 or less?
I wouldn’t recommend building in a pre fab shed.
@@soundproofyourstudio So what should I do then?
So would u need insulation still after filling the cavities with double layers of drywall?
Yes, the insulation is part of the soundproofing. You can buy the cheapest insulation available. It does not have to be Rockwool.
How thick should the concrete floor be?
Most slabs are 4-6” thick. Your goal is to get as much mass as possible so the thicker the better.
I bought a Shed with steel beams very well built everything is awesome except for Air Conditioner Noise. How did you solve that? I tried portable AC the negative pressure made me feel nauseous and I also tried a window AC but that sounded like a jet engine going off. PLEASE ANYONE HELP.....
I recommend the Mr Cool Mini Split.
@@soundproofyourstudio for a 10x10 shed. I'll look for one, i was going to do it for my garage but they wanted 2k for install and 2k for the unit. So now i just leave my garage open enough to let the portable AC unit air to escape
Where can I find a “cleat”?
Just wood 1x1
Pretty sure that original slab will fail/crack/crumble under the weight of the second slab, shed, multiple layers of drywall,…….Not a load it was designed to bear.
That was the contractors call. Hopefully not!
