Topic tags/keywords: acoustic sound soundproofing table saw shop vac dampening loud quiet hearing

Hello guys and gals.
——-
I am wanting to soundproof a shop vac and a table saw.

The shop vac will be placed in a box, similar to other builds that people have done with acoustic panel to lower the dB amount by building a noise reduction box.

The table saw will be done in a similar way. I plan to build a table saw workstation that will be surrounded on all 4 sides, similar to the shop vac. Both will have doors that open so I can get in and adjust settings and also change their underwear whenever needed. The only thing that will be exposed is the saw blade, which seems can’t be dampened by anything, so I’ll just have to deal with that.

Was wanting to know if anyone had any experience with insulation and doing these types of noise reduction boxes.

~My options were going to be

Acoustic panel: 1” Pyramid Foam ( http://www.usafoam.com/acousticfoam/pyramidfoam.html 1×48”x72”x1” panel which can cover 24sq feet).

Owens Corning Insulation: ( http://www.homedepot.com/p/Owens-Corning-R-30-Unfaced-Insulation-Continuous-Roll-15-in-x-25-ft-RU70/202585906 9”x15”x25’ which can cover 31sq feet).

The insulation is only $0.04 less per sq foot, but the insulation is 8” thicker.

Was curious what anyone’s thoughts on this were or other recommendations.

I plan to do caulking and all that to get a good seal and also build some type of barriers inside the boxes for the sound to have more of a distance to travel (with wood left overs).

I also seen a video on youtube about using towels. The test that was done shown that they can work pretty well and you can also find them cheap @ thriftstores/ETC places of this nature.

Thanks for any feedback.

My saw is pretty quiet unless I’m cutting a board.
I had a Craftsman shop vacuum that screamed like a heavily loaded 747 on take off. I bought a Rigid shop vac, it’s a LOT quieter…
Why are you trying to keep things quiet?
If I’m going to do doing something that creates a lot of noise, I’ll wear ear muffs. Outside my shop is not to noisey, it’s insulated behind the drywall…
Either the Eggcrate foam or the Bat insulation you use, would collect a lot of dust unless you sealed it in somehow…

There’s a common misconception that acoustic foam will help soundproof a room. In reality what it’s good for is controlling acoustics. It stops soundwaves from bouncing around creating distortion. To an extent, it does absorb sound, but not enough to warrant using it for the sole purpose of soundproofing, you’d have to get a very thick slab of acoustic foam if you wanted “soundproof foam”. Thick, sealed up walls, sometimes double walls are the way to go if you want to stop sound from escaping.

I just closed mine up with 3/4 ply and it cut the high tones down, one thing to remember the vac needs air for cooling or it will get really hot in the box and kill the vac, so I kept the inlet opening low at the bottom way from my ears..
