There is no "perfect" way to deal w/ a jerk, but the first step is to
knock on the door an politely ask for him to refrain from the behavior
in question--the other jerks whose first reaction is to resort to
equally offensive, rude behavior are a prime reason for eventual
lawsuits or retaliatory actions over such mundane issues.

If a request doesn't suffice, then more aggressive steps can be
followed, but it's almost assured that an initial agressive action will
only provoke an even more aggressive reaction that quite likely would
spread to other areas in spite...

imo, ymmv, $0.02, etc., ...

Thank goodness we have no neighbors...
