I've been doing some research about how to make my own acoustic panels and come across to DIY type of wooden frame and rockwool technique is the most budget friendly one. I literally have no idea how to choose which thickness, how many I need, etc.
So I talked to them on Facebook and they offered me:
Density 40kg/m3
Density 60kg/m3
Density 80kg/m3
Density 100kg/m3
