I'm trying to build a room in my house where my parents and my neighbors won't be disturbed by me playing music. Is there any way, one that's not that expensive, to isolate / cut the sound emanating from the room so that they don't hear it? The walls are already in place if it can help...

I really don't know what to do since the walls are already there... any help would be appreciated. Thanks

You can't use headphones with acoustic drums though and im assuming he is using those...

but anyways, acoustic treatment is going to be a fairly high priced project however you can try hanging thick rugs and such on the walls...
