Ok, i dont have tons of money so i was gonna ask what is the bestr way to get a room to have better acoustics for practice, because my band will have to relocate soon and we are gonna use my attic but it needs to be insulated or something so that sound is good and doesnt go outside all over town. What is the cheapest way and some other ways that arent to expensive, i was thinking styrofoam becuase it is cheaper, what do you think? please help
