Hi, all,
So, my roomate and I just moved into a 1 story home (we are renting) that was built in 1994. The houses next to ours are about 13-15 ft away. We gave up the master bedroom for our practice room for our band. The room is around 17 x 13 ft, has one window, and has a vaulted ceiling. We tested the room to see how loud drum playing would be from the outside, and it's definitely noticeable. We want to sound INSULATE the room, because I know we can't proof it. I need advice on what to do, considering I've never had to do this before. We will be playing mostly during the daytime, and I do plan on talking to my neighbors about it. Also, since there are only two of us, there will only be 2 different instruments (I'm counting vocals as an instrument) playing at any one time. Like I said before, we aren't looking for a soundproof room, but we need enough insulation to keep as much noise as possible from leaving the house. Since we are renting the house, I'm looking for a solution that is temporary and easily installed/removed without causing serious damage to the room. Also, the most affordable solution would be preferred, considering we are both fresh out of college

. I know this is a lot to ask for, but I would REALLY appreciate any advice anyone might have for me. Multiple suggestions are welcomed!
Thanks a lot!
