New acoustic panels are built! I ordered the materials, and with the help of friend and audio engineer extraordinaire Ashton Nagle the 15 panels were built in a day.
We built 2 sizes...2" thick Owens Corning 703 (compressed fiberglass) in a 4" thick frame -and- 4" thick fiberglass in 6" thick frames. The 2" air gap behind the fiberglass helps the panels absorb sound better. It also helps the panels absorb lower frequencies.
A look at the fabrication.
Here are some of the wooden frames after fabrication.
Once the frames were built, we wrapped the front of the panel with black burlap. Burlap is used because the loose weave and breathability allow sound to travel through and become trapped by the fiberglass behind.
Here's a panel with the burlap about to be fastened.
Once the burlap was tightly secured it was time to stuff the rigid fiberglass into the wooden frame.
Here is a picture of the yellow fiberglass which was pushed into the back of the panel. There was no need to secure the fiberglass because once it was pushed in it was held in place by the tension of the snuggness of the fit.
Here is a picture of the finished panels just after fiberglass installation.
Once I vacuumed up any loose fiberglass, the panels were clean and ready to be hung in The Robins Studio.
Here is one more picture of the panels sitting and waiting for their fiberglass stuffing.
The 15 panels took us most of the day to build. Now I just need to find some time to hang em up!
If you have any questions about how we built them or the acoustic principals at play, drop me a line and I'd be happy to answer.
