Scratch Built Acoustic Absorbers for Bedroom Studio

Hey everyone! I'm in the process of converting my bedroom into a bedroom studio for music recording and production, so I thought I would teach Y'all how I made my acoustic absorbers!

Materials

Wood(in my case I used spare plywood)

Foam(I had some extra memory foam from an old mattress)

Exacto Knife

Table Saw

Chop Saw

Drill

Screws

Staple Gun

Fabric to cover the frames(Landscape fabric for the backing and nice fabric for the front)

In our case, we had a small sheet of plywood left over from an old project, so we figured we could build both frames out of it. We first started by cutting the memory foam so we could build a frame around it. Foam is a pain to cut, but with some patience and a sharp knife, it can be done successfully. Once we had cut two foam pieces in the dimensions 2 feet 5 inches by 3 feet, we began to rip the wood on the table saw. We cut each wood strip out of the sheet of plywood to be 3 inches in thickness. We ended up with a total of 14 wooden strips, 7 for each frame. Four of them being for the outside frame, and three for the inside support.

We then began to cut down the strips we had ripped from the table saw to the correct lengths. Since I was making two acoustic frames, I cut four in the length of 3 feet, and 10 in the length of 2.5 feet using a chop saw.

For this step, we used 2-inch screws to attach the whole frame together. We predrilled holes in the sections of wood that were 3 feet long, and then in the final assembly, we predrilled holes in order to prevent blowout and tearing from the screws.

We first started by sanding the entire frame to prevent the sharp edges from puncturing the fabric. Then, we cut out the landscaping fabric in the size of the frame and attached it to the back using staples from a staple gun.

We held the foam in place using staples that gripped onto the wood beams behind the foam. When we began to cover the absorbers, we made sure to stretch the fabric tight for a clean finish. To hold the fabric in place, we used staples from a staple gun. In our case, the fabric we used was extremely thin, which led to a lot of tears from the staples.

For this step, we used a system of hanging called a French Cleat. Here is a great example of how to use one: https://www.instructables.com/id/French-Cleat/

For mine, we used a scrap 2x4 for the system of attaching it.
