Interesting thread.
Coming from sailboats, I really want to reduce engine noise throughout. Sure, there are plenty of soundproofing "sheet" materials out there, which the manufacturers attempt to market with features such as "self-adhesive" etc, but the fact remains, the engine room walls are cluttered with pipes, cables, pumps etc. etc. So, bearing in mind that there should be no gaps, without significant work - removal of ALL (wall, ceiling) fixed appliances - a tidy and successful soundproofing solution in the engine room surely cannot be achieved using sheet materials... Thoughts?
I was thinking the same thoughts John. It would be virtually impossible to box off my engine compartment in sheet soundproofing material. It is a small area with a proper "wall" only on one side.
However - after thinking about it. I wouldn't want to get a perfect seal as it would cut off air circulation. I only need to have a soundproof barrier between the engine and areas where people are.
The way I see it, I plan on first concentration on getting good soundproofing on the underside of the deck and hatches. There is minimal accessories attached above the engine other than wiring harnesses, which are easy to rerun on top of the soundproofing.
Next, I'd concentrate on ensuring there is a good seal on all hatches, using good weatherstripping.
I feel that these two areas will give me the biggest bang for my buck. The sides are less important unless it is a direct barrier to a lower living area. Most of the side areas would benefit with something to absorb noise, but having a complete seal is nowhere near as important as with the barrier above the engine.
