After rereading your original post, I'm thinking you might be droping everything on cement now? If that's the case, I'd first get rubber mats (stall mats) and see how much that helps.
Another thing you can do is tape yourself. Your probably making a LOT more noise than you realize. I know I taped myself to watch form, and was shocked at how loud so of the movements were. Enough that it completely drown out music that was playing pretty loud. I really didn't notice it when I was doing it.
