Is 15 squares better than 1 rectangle for soundproofing?

Goal: Minimize sound coming from outside of the studio walls.

Question: is it more effective to have a wall built out of one rectangle or multiple squares fastened together? I’ll show you what I mean by posting a picture of a square I have built.

This studio is intended to be modular.

I have not thought too far ahead about how I would fasten the squares together. What do you think?

side note: the square in the picture is not complete yet.

Square

Here’s the plan as mentioned in a reply to a commenter:

I’m figuring it out as I go but here’s a general plan:

The small rectangular house I’m in has a living room. I cannot drill or very minimally drill if that into the walls. My plan is to build a modular studio. Built by fastening pieces together. The floor will be built probably in three parts. Three rectangles made of 2x4’s and ply wood but with plenty of cushy stuff and a rug to top it off. As far as the ceiling that is up in the air, no pun intended, and as far as the walls go I will somehow fasten these square together. That is somewhat dependent on the feedback I receive on this post. I initially wanted to do big rectangular pieces for the walls but it might be harder than just making like 30 of these squares and figuring out how to fasten them together I’m not sure.

Will it be perfect? No. Will it be professional? No. Will it block sound? Yes. At least some and that’s ok. It’s adventurous, spontaneous and I’ve never done anything like this before but I’ll figure something out.

Let me know if any of this is ill advised or naive.

Edit: I want to add that this square’s purpose serves/served as a model if you will or a recipe for how the soundproofing structures will be built.
