We had a hard time after the fact getting anyone to work with us on acoustics because it was a much smaller job than they liked. Most work with architects during construction on large or multiple spaces. None of them called us back with bids even when we were able to get them to visit. We finally got a lead on a musician who also did acoustical installations. He was perfect because he was used to doing music studios with his musician friend so they thought our job was big. The musician also had a more intuitive sense of sound and what we needed. We had hired an acoustical expert who came out with machines and made everyone stay out of the room. Then he measured using different sound waves on all the walls. It took most of the afternoon as I recall. Then he produced a report full of numbers that only our electrical engineer could interpret. He calculated that we needed to cover every square inch to meet the standards in the report. But the real problem was that the acoustical expert only understood sound in terms of numerical measurements. When we asked if a quilt on one wall would be as good as fiberglass panel, he said, I don’t know. I don’t have measurements on quilts. So find a musician of you are already built and don’t have a friendly architect around. They will go around hooting and hollering and knocking on walls and tell you how well this or that will work where. No numbers.
