Hi Alan.
I saw you were good with sound dampning and had a few questions. i am finishing a rebuild on a 30m wooden catch. I have a full size engine room with 2 340hp mains and 2 27KW gensets. My question is how to finish my walls and cealling. Now I have this. A bulk head for and aft of my engine room. 6mm rubber bushings with 15mm plywood attached to them. In between we have fiberglass mat insulation. now this is my question. The visable walls in the engine room are untreated plywood. Im going back and forth on ither painting or lining with steel of some sort. If I go with steel do I use perferated panels or solid panels? What do I do to keep the vibrations down between these panles and the plywood? Or do you have a better sugestion.
