I live in an apartment and one of my rooms is kind of echo-ey, which is probably bothersome to my downstairs neighbors. I currently have nothing on the walls, but was hoping to hang something there to absorb sound. Ideas?
I'm can't spend a lot of money on this, and after doing a bit of research, I found something called homasote, which is a fiberboard. I plan to cover rectangular pieces of it in pretty fabric to hang on two of the walls. I have no idea how much homasote costs, or how effective it would be. Are there other materials I could use? Any advice or suggestions are appreciated.
