We did more pre tests to see not only the overall noise levels, but the amount of echo or reverberation. We used a balloon popping sound on a computer to keep the sound the same in every test. Below is the video on how to set up this test. We also are trying another way of putting up the sound panels, so they are glued to plywood instead of glued onto the wall with adhesive spray. We arranged the panels on five sheets of plywood, careful with the overall design, then used textbooks to help the glue set. Hopefully this time the panels stay on the wall more than a month!
