Here is a step-by-step tutorial on how to make acoustic panels:

1. Materials: 1x4 boards, screen material, insulation, fabric, and nails.
2. Cutting the Boards to Length: Cut 2x 48" x 1"x4" per panel.
3. Glue Up the Boards: Use some glue on the joints so they're a little stronger after you nail them together.
4. Fasten Them Together: Nail the boards together.
5. Add Screen Material: Staple screen material to the back of the panel.
6. Add Insulation: Fill the panel with insulation.
7. Add More Screen: Staple more screen material over the insulation.
8. Cover in Fabric: Staple fabric over the screen material.
