So I'm currently an international (Latin) grad student at some US university and wanted to know how to improve my current work space situation.
I share an office with another 2 Chinese grad students, that part is fine. Two professors access their offices going through ours and one of them is very "particular".
The issue is this, he is very impolite to all of us, when he comes out of his office he sometimes hits one of the other students desk and sometimes he does it so hard that things from his desk fall off, once he even hit the other student, and since he couldn't open immediately he continued to slam the door several times against him while he moved, not super hard but still..., he also plays music rather loud so even when his door is closed we can hear it very clear and he plays the same song for a loop all day long (the other day I learned that one of the songs he plays in a loop is the US national anthem).
All of that happens without a single word coming out of his mouth and he avoids eye contact with us.
Additional context, I'm a relatively new international student and he is an American tenured professor.
How can I improve our office current situation?
