How to build a Mic Shield for your Home Studio

How to build a Mic Shield for your Home Studio

A Mic Shield is a great tool for those that plan to record in places that have the possibility of being noisy. I.E. basements, bedrooms, classrooms, or anywhere there could be AC noise, electrical hums, road noise, or the shouting of children in the hallway.

I used my bedroom as a recording space for several years, battling noise issues EVERY TIME I recorded, even when I was super careful about the time of day, placement of mic, etc. It wasn’t until I used a mic shield while visiting a professional studio that I realized just how helpful they really are!

Mic shields can easily run for $100+, which isn’t too bad as far as audio equipment goes – BUT, why BUY one when you can MAKE one and customize it for your own use?

Here is the tutorial I used when learning how to build my mic shield. It was very helpful, and was definitely the basis for my project, however, I did make some adjustments to make my mic shield sturdier and cover more space.

Mic Shield Supplies:

Mic shield supplies

45-gallon paint grids

1Air Conditioning filter foam OR 24’’ x 24’’ acoustic foam

(you can use multiple smaller pieces, the kind I had just happened to be one whole piece)

1Roll of electrical tape or duct tape

1Bag of mini zip-ties

1Can of spray adhesive

1Hot glue gun

I put links here for you to find all of these items online, but they can also be picked up at your local Walmart or hardware store.


Step 1:

Flatten out the hooked ends of the paint grids using pliers.

Step 2:

Bend the paint grids into a semi-circle and tape the “hook” ends together. Wrap tightly with electrical tape so the grids don’t wiggle. You can also hot glue first, then tape around the ends.

Note: It may be a good idea to bend two grids the exact same way, then the other two the same way. This will ensure that both the top and bottom layers of the mic shield will be symmetrical.

Step 3:

Use the zip-ties to tie together the top and bottom layers of the paint grids. Pull the zip-ties tight to avoid slipping, and be sure to attach all the zip ties in the same direction. This way, the ends will all be pointing the same direction, making it look better once the ends are chopped off.

Step 4:

Use the spray adhesive to glue the foam to the paint grids. Spray the adhesive to the foam, then press it to the metal (I tried first by spraying the metal….it doesn’t work too well and is pretty messy!) Press the foam to the metal starting in the center of the grids, and move outward.

Step 5:

Go back through and hot glue the foam around the edges. You should be able to peel up the foam and glue it back down easily. This just adds another layer of protection from slipping and losing your foam.

And that’s how to build a mic shield for your home studio! In total, this project took me about an hour to complete, which is well worth the work in my opinion.
