I'm currently an undergrad student at a music school and during the school year I have access to the practice rooms where I can practice anytime I want, for as long as I want and make as much noise as I want without bothering my family or neighbors, but during the summer I don't have this luxury. I'm afraid that my incessant practicing is going to drive my parents crazy so I have been thinking about building a little pratice module in my bedroom to try to dampen the sound. I'm on a very tight budget so it is not like I can spend a couple of thousand dollars to sound proof my room. I was thinking of buying some plywood and egg carton foam that they use in studios and basically building a box. Does anyone know if these materials will help dampen the sound at all? Or, does anyone have any ideas about how not to drive your family and neighbors crazy? I have a "silent brass" practice mute but you can't actually practice with those things. Thanks for your help!
