Planning to install acoustic panels on a drywall. To simplify the installation, I'm considering using a 13mm OSB board cut into battens and attaching it to the drywall at cc 60. It's a bit tricky to find the studs behind the drywall.
What do you think about it? It will protrude a bit, but that's not a problem. Will it hold? Will it be bad if the acoustic panels don't sit flush against the wall?
I saw that you can do it with 45mm battens and insulate behind to achieve sound absorption class A, but 45mm is unfortunately a bit too deep.
