I did on my 37. It had no insulation at all when I got it, I added one of the available soundproofing kits (got it at West Marine) and it certainly made a difference. It's still noisy but much better than it was.
I did my Kaufman 47 engine room with Sound Down sound proofing paint then bought the tiles from Sailor Solutions and used some sound aluminum tape off Amazon. The tiles were easy to cut and stick on. Beats the foam and tack options..
