Dealing with chop/cold saw noise

We will be getting an Evolution Rage 4 for general box tubing cutting but I am concerned with how to deal with the noise. Our shop is pretty small and the Rage 4 is over 100 dB under load. My initial thought was to make a hinged wooden enclosure, lined with sound dampening foam. The operator will be wearing ear protection but it is impractical to have everyone in the shop doing the same every time a cut is made. Teams with chop saws or cold saws, how do you deal with the noise?

Re: Dealing with chop/cold saw noise

Often times in the USC shop, we'd move the saw just outside for the extra working space and the comfort of everyone else working. Getting close in on the saw creates its own challenges (especially with long workpieces), but is there anything that can be rearranged in the shop? Shelving or cabinets you already have may get you a lot of the way there, or at least be a useful mount for additional sound deadening.

Re: Dealing with chop/cold saw noise

Consider setting it up outside. During the winter on 3467 we would move the miter saw outside for the safety of everyone in the shop.

We simply have everyone in the shop keep hearing protection with them when chop-saw usage is a possibility. Electric epro works great in these cases. We have 4x of these. We can comfortably talk to each other at a normal volume and have instant-on hearing protection if there is a loud noise.

Re: Dealing with chop/cold saw noise

A chop saw is incredibly noisy cutting Aluminum; a cold saw with the slower cutting speed is not very objectionable at all.

A chop saw is likely faster cutting material; but having both available in our shop I use the cold saw 90% of the time. I find that a cold saw also produces a cleaner cut.

Re: Dealing with chop/cold saw noise

On 449, we have hearing protection for whoever is using the saw, and we alert everyone else in the room by shouting "Chop Saw!" before the saw is used, so that they can cover their ears if they wish.

We can't really move the thing outside.

It's consistently 20 below (or colder) for us so setting up outside isn't an option for everyone.

Well, it ain't called a COLD saw for nothing.


Meanwhile my big issue was that it was simply too hot all build season to be outside.

Our shop has got a little awning over the door, perfect for taking the chop saw out in the rain.

There are a variety of ways, both fixed and portable that you can dampen the noise of your saw. To start, most standard office partitions (cubical walls) are designed to act as sound dampeners and might be a good semi-portable option for closing off the area around the saw when in use and blocking most of the noise (if your lucky, your school might even have a few in a storage room somewhere that you might be able to get a hold of). Additionally, there's tons of different kinds of sound dampening panels and foam that could be attached to the walls or ceiling around the Saw to further help with reducing sound.

I have a 3D Printer I keep in my bedroom at home which can make it difficult to sleep (due to the noise) when it's running an overnight print. I built an enclosure for it using foamboard and some acoustic foam and it has probably reduced the noise from the printer by a good 10db or so and cost less than $20 to build (granted this is a larger-scale problem, but it's still relatively inexpensive if you don't mind a DIY project).

My local college's vocational shop has always had their chopsaw & bench grinders outside, underneath an extension of the shop roof.

Same. We also banish the table saw out there. Along with anything else that's easily movable and needs to be NOT in the way.
