On the noise, my plan is to double down on the mat material (Costco / Lowes roofing stuff)) and somewhere in there lay-down a very thin membrane mat, almost looks and feels like surgical rubber. From what I have read, different materials are better blocking those noises that come in on different frequencies. I am then going to rubber mat the floor with coco mats as the topper. Does this makes sense? .... Wait! I am not in this to make sense ... Right?
