Like Jeff said, it is fairly loud. Baffling, ear muffs or remote location would be a good idea. Mine is in another room, adjacent to my shop which helps a lot, but I still want to put baffling around it to reduce the noise even further.
I used cheap sch 20 sewer grade PVC for my ducting and ordered hoses & fittings from Amazon. I used the clear Powertec hoses & Powertec hose clamps - I used 4" hoses & if I needed to step down to 2" for some tools, I did that within a couple of feet of the tool.
I got my dust separator cap & tubes at Rockler and bought a metal garbage can at Home Depot. I also got my blast gates at Rockler - I just liked theirs better than any others.
