I wanted to see what I could do to quiet this setup. Using some scrap 1/2″ OSB and Styrofoam I built a box and cut some holes for the 1-14″ hose I found at Home Depot.
Unfortunately the Styrofoam doesn’t do a very good job of reducing the sound. Only a 10db drop when it was done. I’ll be looking for better sound reduction material. A lid slapped together from MDF scraps. I may add a baffle to the lid later and route the exhaust out through it later. The hose on the front side blows, the back side sux.
Note: I realized long after creating this post that I never discussed the vacuum I was using.
Well here is a separate post about it.
