Building acoustic treatments for the home theater can dramatically improve imaging and focus.
Acoustic treatments can improve sound in a way that no individual component can. Since treatments affect the acoustic signature of the room after the speakers have reproduced the sound, the sonic signature of the system is maintained. Acoustic panels mitigate the effects of reflections from walls and other surfaces, improving imaging and focus. Making DIY panels is not extraordinarily difficult, using conventional batting, insulation, and wood panels.
Instructions
1. Cut a plywood sheet to the desired size.
2. Cut a 2-by-4 plank to fit the sides of the . Place the cut pieces around the edges of the sheet, forming a frame. Drill a 1/16-inch hole every 6 inches on each section of the frame, penetrating into the sheet's edges.
3. Drive a screw through the drilled holes, attaching the 2-by-4 pieces to the plywood sheet.
4. Cut two sheets of batting and one sheet of insulation to fit within the frame. Make a sandwich of the materials by placing one sheet of batting against the plywood. Follow with a layer of insulation, then place another layer of batting on top. This process allows for a combination of bass absorption and controlled high-frequency reflection.
5. Cut a piece of fabric large enough to wrap entirely around the frame, leaving 6-to-8 inches of material on the back of the plywood. Lay this material flat against the work surface. Place the panel face-down against the fabric. Wrap the selected material tightly around the entire assembly.Staple the excess to the plywood backing, pulling the material tight as you go, to prevent wrinkles.
6. Attach two picture hangers to the back of the panel,--preferably into the edges to hit the 2-by-4 frame--Using wood screws and a drill with a Phillips attachment. Loop the hanger wire around the hooks.
