DIY Acoustic Wall Panels


This is my first attempt at building DIY acoustic wall panels.  The frames are constructed of the following:

1 X 3 fir strips from Home Depot
#6 1-1/2" wood screws

My woodworking skills are minimal to non-existent so I used simple butt joints.  Holes were drilled on the side, top and bottom panels for additional sound absorption.  These were cut using a 1" hole boring bit.  One brace was placed across the middle of the back and four corner wedges were cut and screwed in place to hold the fiberglass panels.

The fiberglass material is 2-foot by 4-foot ceiling tiles that I found at Menard's.  The manufacturer is Capaul, and the model is Strata.  Since these are only one-inch thick, I used two tiles in the panel.  The tiles come with a white textured vinyl backing on one side (which would normally face the ceiling side of your room).  I left the vinyl on the back piece to keep any stray fiberglass particles in place.  For the front layer of fiberglass I peeled the vinyl off.  It came away cleanly and easily.

Here are some pictures of the panels before covering with burlap (click on thumbnails to view full-size image):
