I'm looking for an inexpensive way to soundproof my bedroom or possibly just a part of it (with a sound resistant shelter). Removing all the sound is impractical, but I'd like to suppress it to the point where it might sound like it's coming from outside rather than next door.
I have some music studio equipment in my room which I use to record myself singing. The equipment is too bulky and awkward to move to a different location for recording. I know that sound travels easily in the house we share, especially through the air vents. When my roommates next door speak at normal levels I can hear every word they say.
I'm currently renting so permanent modifications to the room are out of the question. I would prefer the final solution to not be too expensive. I don't have many tools but I might consider buying a few for this project.
My current idea to solve this problem is to construct a sort of shelter made with PVC pipe and moving blankets which I can set up and take down as needed. Is there a better solution? Should I consider anything in particular with this potential solution, such as different materials or a certain shape for my shelter?
