I have had a sealed back panel actually resonate. What happens is the back panel is in contact with the fiberglass/insulation and will resonate with the fiberglass. I had to cut out a large section of that sealed back to resolve the problem.
DIY Acoustic Panels
Hi everyone,
I am looking to make an Acoustic panel for my fireplace as an insert and wondered if it should have a solid back? I have seen both designs “open back” and “sealed”.
Any ideas as to which might work better?
