How to Make Acoustic Wall Panels

If you are setting up a club, a recording studio, or any other location where there is likely to be quite a lot of noise, acoustic wall panels are essential. Acoustic wall panels provide a low cost and effective way of insulating sound. They work by absorbing reverberations, and muffling the sound. In a recording studio, they can also make the quality of recordings sound better. You can buy acoustic panels already made, but you can save about half of the money that you would otherwise spend, if you make them yourself.

Tools and Materials Needed:

  • Acoustic insulation material
  • Fabric
  • Lumber for frame
  • Plywood sheet
  • Wood glue
  • Saw
  • Staple gun and staples
  • Scissors

Step 1 – Make Preparations

Optimally, you should have about 1 panel for every 4 foot square section of wall. Calculate how many panels you are going to need in total, and account for a couple of spare ones. Most of the materials which you need can be purchased at any hardware store. You need to have appropriate lumber, preferably 1x4 dimensions. You also need to have some appropriate insulation material. The best is rockwool. Each panel of insulation will be used for 1 acoustic wall panel. These panels then need to be covered with fabric. You will need 3 yards per panel. Don’t worry about the material, the only purpose of this fabric is to provide a finished appearance. It has no influence on the sound insulation itself, so the only thing that you want to consider is a color or design that you like.

Step 2 – Build the Frame

The frame will simply be a square shape in which the insulation material can fit. Cut the timber for the frames into 4 pieces including 2 4 foot long pieces and 3 3 foot 10 inch lengths. Attach these to each other, to form a square. You can save yourself some time by getting these frames already built. Use wood glue to attach the parts the frame together. For the back of the frame, you need an appropriately sized section of plywood. Mark a 4 foot square section on the back of it.  Cut out the section with a saw. Attached the plywood to the frame with wood glue. When you have built the frames, leave them overnight for the wood glue to dry. This way, you have a 4 inch deep box in which you will have the insulation. 

Step 3 – Apply Insulation

When the frames are dry, fill them with the insulation material by unrolling it into the box. It is very important not to compress the insulation material too much, as this makes it inefficient. Nonetheless, it is important to fill the frame completely, not having any areas in the corners which are uncovered.

Step 4 – Apply Fabric

The purpose of the fabric is to make the wall panels look finished. It also helps to hold in the insulation. Cut the fabric, so that it covers the 4-foot square frames, and overlaps each side by about an inch. The edges of the fabric should fold over the edges of the frame slightly, where they will be stapled onto it. You can use an appropriate type of glue for a more tidy appearance.
