Temporary sound solution for apartment?

[NewFoundation]

Hey guys. I'm in need of a temporary and budget friendly way to soun dproof a small apartment room. I'm thinking of putting some studio foam squares on the 3 exposed walls but I don't want to have to glue anything, as it is an apartment I will be leaving soon. Btw this is the room I plan on putting studio monitors in.

By "sound proofing" do you mean you need to stop sound from getting out of the room? This is called "isolation". Foam will not help to isolate in any way, shape, or form. "Soundproofing foam" is an oxymoron. In order to isolate, you'll need to do construction (which likely wouldn't be possible in the apartment)

If you're looking to treat the room so it sounds better, foam will only deaden the treble in the room and do nothing to tighten up the sound of the room at all.
