Sound Cancelling Portable Studio Box





Introduction: Sound Cancelling Portable Studio Box

Want to record music at home but it's too noisy and too expensive to create a soundproof room? Well I have the perfect solution for you. Easy and less than $15 (A lot less than the hundreds you would spend to treat a room). All you need is:

*Storage tote (Free if you empty out one you already have)
*Memory foam bed pad ($9.99 @ Wal-Mart)
*Spray adhesive or medium tube of gel superglue
*Sharpie marker

Step 1: Measure and Cut Pad

Place pad around the outside of tote and mark with sharpie the length and width of the three outside walls.

Step 2: Lining

Line the inside with piece of pad you cut, leaving space for an arch towards the back. The arch will produce better sound.

Step 3: Top and Bottom

Next cut out two pieces for the top and bottom of booth box. Line the bottom. Use a sharpie to Mark where there is excess padding then cut the excess away, then place back. Save all excess pieces to stuff into empty spaces between padding sides, top and bottom. Spray the adhesive or spread glue in each section you're working on only after you've gotten the padding cut perfectly to your liking (!Use glue products in a well ventilated area or outdoors!).

Step 4: Finish!

Allow glue to bond for about 30 minutes, then cut off any excess around the edges and add any scraps in creases. Now you're ready. You will notice a remarkable difference in the sound quality of your recording, and you didn't have to break the bank to do it.

Hey iamcrisstylez, this was a really great post-- I discovered it from NighthawkInlight's video that links back here.

However, I tried testing my version out with a preamp/Neumann and the sound still has strong reverb/echo. Is it because the width of the Tub I am using is roughly 1.7 feet at the outermost edges?

Do I need to buy a bigger tub or is there a trick for stuffing more excess mattress foam in specific areas of the tub?

Appreciate any insight!

Great! Less expensive then the screen I got, but I guess that it still works as good. Thanks for the instructions


I'm wondering about a simpler design that could be interesting. Ideally, a "corner" reflector can be interesting if the angle is sharp enough that it traps sound reflections in a very long path going into the corner. This multiplies the effectiveness of the sound insulation. Also might fold up better.

Hmmm... I'm trying to see this in my head, but I'm still learning so I'm a little confused. Exactly how would you do it?


I should add -- your original design is so simple and straightforward and easy to build that it excels for that reason, so I actually would recommend it if it does the job. And the "tub" shape could provide dual purpose, where you could load it with recording equipment, etc. during transport, so the bulk in a sense is not a negative. Well done!


It would basically look like a book -- two boards with insulation hinged where the book binding would be. You open the book, and the microphone is placed probably midway from the front to back corner (hinge). I haven't designed it completely in my head. The open top and bottom could probably be covered by some additional hinged panels with insulation that would swing over. It would be a big thick sandwich when folded up, so some care needed designing the hinges to allow for the thickness of the insulation. If you used some nicer insulation that could be sewn into "cushions", you could possibly fold the contraption with the insulation on the outside to make hinge design a little easier. But then the hinges would need to be able to sweep a larger angle, not always available.

Probably the best variation on this design would look like a four-sided "horn" (like civil alert sirens) instead of a book. The concept is that the steep angles funnel extra sound back into the corner, where any surviving reflections make more and more bounces, increasing the absorption... in theory anyway. Something to try experimentally. The goal is to get better absorption, or same absorption with less insulation and more portable design. Just an idea to try out. The proof is always in the pudding; it might be inferior to the original idea.

So easy and simple ! I should try it !

Great build OP! I built the same thing but MUCH MUCH simpler. Your's looks pro compared to mine. I used a cardboard box, standing 'up' with the microphone in it the box is approx: 18" high, 1' wide and 1' deep. I used 1.5 in used foam. I cut it so that it all sticks in with the sides keeping the top/bottom in. I built it in less than 10 minutes. I use a Zoom H2 field recorder on a tiny tiny tripod. IT WORKS FANTASTIC !!! Studio quality sound. Everybody talking about microphone pickup shapes need to keep in mind this build is to 'improve' the recording quality. If the OP's build improves the recording quality 1/10th as much as my crappy build did his is going to be awesome and not "absolutely useless"!

Having constructed a full-size (approx 2m x 80cm x 2m high) soundproof room I can see the convenience of such a project. (don't think I can do an Inst. about it as I don't have much detail of the construction available, only a few photos).

I am very sorry but:
That kind of recording equipment ist absolutely useless.

Where does the microphone pick up the sound? Exactly. On the OPEN side.

If you want a cheap solution, stand with your back to your door and hang blankets / a matress over it.
