Hey, you sound like you may suffer from some hyper vigilance...is it the sounds that really get you irritated or what they are saying? Either way I completely understand what you are saying. Being in a busy house myself I understand the need to isolate in your room to TRY to block out what is going on just for some peace. If you scream "SHUT UP" then you look like the asshole but if you explain it calmly you sound like a nut job or you are unheard. It sucks.
